Machine Configuration Profiles Machine profiles let's you create new custom profiles for your machines. Note the buttons next to the Machine Profile Selector: - Simple is for creating profiles that have the minimum information needed to make G-Wizard work. Creating these profiles is quick and easy. A lot more information is collected. Here are all the different kinds of information G-Wizard can use. Most of it is on the Advanced page.
G-Code is the language used to control CNC machines. Your machine's CNC controller probably executes g-code. If so. There's no need to register. The articles are all listed below. Some machines with proprietary formats can also run g-code. Want some easy G-Code Training? Maybe you just want to learn more about a specific G-Code related topic or see particular G-Code examples. These articles are CNCCookbook's free course in g-code. Every CNC machinist should know g-code. In fact the overwhelming majority read.
We recently did a survey to assess the g-code skills of our readership. Experimenting is one of the best ways to get a good grasp of g-code. If you're interested in CNC and machining. It simulates g-code as well as decoding it for you.
You can try out different g-codes and see visually what they do. In other words. Working the exercises is a whole lot easier if you've got some software to help you play with g-code. Check them out--it's easy to improve your g-code proficiency and well worth the productivity gains. That's what our G-Code Editor software is all about. Work at your own pace. No matter what stage in g-code learning you are at. Page 8. A little bit at a time. If you're not yet able to do that.
At the end of each section is a Quiz to test your skills. You should not be suprised to learn that many are quite proficient with G-Code: We were impressed at how many readers can write g-code programs from scratch. Page 9. You'll find G-Wizard Editor not only makes it easy to work with g-code and try the exercises in the course. We're by far the largest CNC blog on the Internet in terms of readership.
For more information. The second thing you should do aside from following a course and using a simulator like G-Wizard Editor is to start following some articles about CNC. You'll see things that raise questions and get you thinking about the basic concepts in new ways. We encourage you to sign up for the free 30 day trial--that's plenty long enough to work through all the lessons free of charge.
Or you can join We post articles for all levels of knowledge. For example. There's nothing else like it available anywhere. CNCCookbook Basic G-Code Course questions to go back and review anything you missed so you'll be solid before continuing to the next section. Getting some random inputs about a variety of topics is another way to help the juices flow. To get a good source of such inspiration you could hardly do better than to subscribe to our own CNCCookbook Blog.
This helps all of the ideas to connect better. Signing up is easy--you'll automatically be added to the list if you start the day trial of G-Wizard Editor. Avoid having to run back to your CAM program when simple changes to the g-code would do the job.
Learn how to improve the g-code the CAM program puts out for better results. Make it faster and easier to fix the g-code when you run into a problem due to a bug in the CAM or post processor. Get a second opinion on the CAM's g-code before you find out something's wrong at the machine. You should not be suprised to learn that many are quite proficient with GCode: If you're at the "Read or Tweak" stage.
Armed with a good understanding of g-code. Understand better how to tweak your CAM software's post processor so it produces better code from the start. These are all valuable skills that increase your productivity as a CNC machinist.
It will do exactly what you tell it to even if that means rapiding a spinning cutter with 20HP behind it directly into your expensive fourth axis and destroying it. G-Code is a computer language aimed at telling your machine what to do.
There's no need to be afraid of g-code. For that reason. Most importantly. Getting to that stage is another excellent reason to spend time learning the g-code. The trouble with computer languages like gcode is that unlike people.
They assume you know exactly what you want. It will give you insights into your machine that enable you to extract more performance and to protect it better from accidents. According to the survey. Develop a greater facility for working at the console of the machine directly. In addition. We'll be including some exercises with each section that involve working with GWE. This makes learning a lot faster and easier when you have that immediate response versus trying to plot things on graph paper or work with your machine controller.
Think of it as a convenient etch-a-sketch on which you enter g-codes and can immediately see the toolpath that results. From time to time we'll also include videos that help illustrate how to go about using GWE for the exercises.. GWE has a "Hints" window that shows you what each code does in plain English. GWE gives you lots of additional information that's hard to get at with most controllers.
More importantly.. With GWE. If you'd like to learn more. If you don't already have GWE. We'll be using it for many of the exercises on each section of this course. Hence even though the diagram shows what looks like a left-handed system. Now extend your second finger at right angles to the index finger. It's not a big deal otherwise and you'll get used to what your machine uses pretty fast.
Those three fingers are now pointing in the directions of positive X second finger. This whole handedness thing is just a way to remind yourself which way the coordinates go.
Even though most machines are right handed. Now here is the tricky part: Even if the table moves instead of the spindle. What that means is that for motions of the table.
Y index finger and Z thumb. Handedness is spindle motion and reversed! Here are some common types: The cylinders in each drawing represent the spindle of the machine. Lathes can get a lot more complicated than the simple 2-axis version I've shown.
Be sure to have a look at exactly how the axes are laid out on your machine. In general. Note that we have added two rotational axes to the basic mill diagram to provide an AAxis and a B-Axis. Copyright by CNCCookbook..
X1 Y2 Z3 That's actually the easiest to read once you get used to it. The example I just gave used inches. For rotational axes which you'll only be using on a 4 or 5 axis machine. Spaces between the letter and its value are optional.
We'll talk more about changing units in a future article. X1Y2Z3 You get used to reading them all run together like that quickly. It's pretty simple: The G-Codes to change units only affect how the machine interprets the numbers.
It's up to you to know which default the system comes up in and to change the units as needed. They don't change your program. Try not to change units in the middle of a program.
Rotating the 4th axis to the 90 degree position might be done as A It's too confusing otherwise. UVW may be used alongside XYZ to refer to relative coordinates without needing to change back and forth between relative and absolute modes. We'll show you how to make that switch when we talk about how to move with G-Code.
This is easily done with relative moves: X1 Y1 X-1 Y-1 In essence. On some controllers. There are lots of cases where relative moves are handy so the ability to switch back and forth comes up a lot.
Now we have a 1" square whose lower left corner is the initial point. For now. Perhaps you've used your edgefinder to locate the cutter precisely on some feature of the part. I can make the move absolute or relative and it doesn't matter. Y3 I dropped the commas. A little later. Now just by changing the work offset the same program can work to make the part on either vise.
We can put one on the first vise and another on the second vise. How do you make one program that can do both parts without having to change the program for the position of each part?
The answer is that we use a Work Offset. They're digital power tools for the CNC machinist and are very handy. I mention this because any time you get a chance to learn about offsets. We'll cover them in greater detail later. More on GG19 when we talk more about arcs. There is a plane for each combination of the linear axes XYZ: A plane is a flat 2 dimensional space defined by two axes. Each is held in a vise on your table at the same time. Offsets are another fancy way to think about relative motions.
Let's suppose you want to machine 2 identical parts. If you draw an arc without specifying a change in the plane. More detail on those later. Most CNC controllers have an offsets screen where you do that. There are lots of different kinds of offsets in CNC. Which direction is the positive increasing positive coordinates for each axis? Which direction do increasingly positive coordinates in the g-code move the table and spindle? You know about planes. But first.
Top is a view from the XY plane. Front is a view from the XZ plane.
We'll refer back to it a number of times as we go through the various exercises. We'll shortly introduce the notion of MDI. You know there is the possibility of both relative and absolute coordinates.
It's a good introduction to the basics of moving your CNC's axes. By default. Make sure to leave the manual handy. You know what units are used to measure the coordiantes.
Have a look at it in each view. There are views for Perspective. Get out the manual for your machine and find the diagram that shows how its coordinate system works.
You know how to express coordinates in G-Code. Download the sample engraving file from our download page. You know how to visualize the coordinate systems relative to your machine using the left handed rule. Form the left-handed and right-handed coordinate systems with your own hands and visualize which way the axes run on your machine. You know that offsets let you shift the coordinate system around for various handy purposes.
G-Code mappings. Sometimes the same function will be supported by different g-code numbers on different controls. This is not to say they are better than other G-Code dialects. Not all controllers support all G-Codes. Which G-Codes are Supported. Some wag once joked that the great thing about standards is there are so many to choose from.
It pays to understand the special capabilities of your machine because they were probably put there to save time based on feedback the manufacturer got from its customers. In terms of sheer numbers of users. G-Code dialects differ in a variety of ways. Most manufacturers have added their own little bells and whistles to make their dialect better for competitive and marketing reasons.
Heidenhain's Conversational CNC language. G-Code has an extremely long history. The original EIA standards work was begun in the 's but the first standard wasn't released until So it is from G-Code. While much of it remains the same from controller to controller setting aside alternatives to G-Code from things like Mazatrol. Haas has a series of special g-codes for pocket milling.
Parametric programming with macros is something that emerged after the basic standards were in place. Fanuc Macro B is probably the most common standard for it.
Many controls are very limited in their capabilities around Macro Programming and there are a lot of detail differences around exactly how Macros work. Many G-Codes need additional information to do their job, so they use other words letters to collect that information. Exactly which words collect which information can vary from one control to the next. Some controls allow G0 or G Some insist on G Some allow numbers with no decimal, others insist on a decimal or even a trailing zero.
We'll talk more shortly about what all of this means, but for now, be aware that these differences exist. For simple programs and MDI use, obviously a lot of this won't matter. But, for writing complex hand-written G-Code or trying to understand why the G-Code your CAM program emits isn't quite right, you'll need to be aware of the dialect issues.
The job of the Post Processor or "Post" as most machinists call it , is to convert generic geometry moves in a dialect independent and often G-Code independent language to the particular dialect of G-Code your machine uses. The Post also gives you a lot of flexibility to tailor your CAM output to the practices your shop likes to use, so it is a handy way to customize the G-Code output of your CAM.
If you frequently are making the same hand edits over and over again to your G-Code, it's worth investigating whether a change to your Post would eliminate that hassle. You can even modify the Post to save your operators some time. Maybe you want the table on your mill to move as close to the enclosure door as possible at the end of a job to facilitate loading and unloading.
That's a logical thing to have the Post do for you. Depending on the CAM package and its Post capabilities, sometimes very powerful flexibility is an option. For example, the Post may be able to popup a custom menu allowing you to choose some options you've specifically designed for your shop's needs on every Post. Posts are typically languages unto themselves that are often unique to the CAM package.
In some cases, the CAM vendor wants to sell services customizing Posts so may not make it easier for you to obtain the knowledge and tools to modify your Post.
In others, they're perfectly happy to help. There are also generic tools out there that specialize in making it easy to do your own custom Posts. Posthaste is one example of such a tool. That will get you started down the road of using the right dialect as you use GWE as a cnc simulator also called a g-code simulator, or a cnc or g-code verifier for your machine.
Presumably by now you have registered for GWE and downloaded and installed it. Very Important: For purposes of this tutorial, unless we specifically say something different, we're going to assume you're running a Fanuc controller. When you follow along with our exercises, you should run a Machine Profile for the Fanuc Controller, preferably by downloading our canned profile.
When you go to program for your machine, you'll need a profile properly set up for your machine! Hopefully that makes sense to you. It's inconvenient that all CNC machines don't use the same G-Code dialect, but it is a fact of life you may as well get used to sooner rather than later. Knowing that there are differences and having some idea what they are will make it easier for you to exchange information and g-code with other machinists.
You'll want to make sure all of your tools are on the same page as your CNC controller in terms of having the same Post settings, otherwise you'll have all sorts of problems getting your G-Code working right. As we go through each G-Code area, we'll try to go over some of the Dialect differences so you can make sure all your software is doing the right thing!
There are lots of "Modes" in G-Codes. A "Mode" simply means the CNC Controller is remembering some behavior from the last time you told it what to do. People often think modally, meaning if you don't specify every detail, they fall back to assuming you mean to do things the way you did the last time you specified.
When you run a G-Code program in the GWE simulator, it shows you which modes are in effect in the little box under the backplot:. We'll talk more about how to run the G-Code Simulator in GWE soon, but for now, just be aware of where the currently active modes are shown below the backplot and in the little box to the right. The red outline shows the area that describes the current state of the CNC controller, which includes any modes.
The screen shot shows the modes that are active at the very beginning of the Engrave program. You can see the following modes are in effect: This mode means all motion is in straight lines at rapids speeds--the fastest your machine can move. Best speed mode means the controller will make best efforts to move at the desired speed. An alternate mode is called "exact stop". More on that later. Motions are in Inches rather than MM.
Motions are absolute rather than relative. A lot of G-Code programming involves making sure the right modes are in effect before telling the machine what to do next. If it doesn't. Set up and save a machine profile using the Fanuc Mill profile so you can follow along with the examples and exercises for this tutorial. Get familiar with how your controller shows its current state.
Go through each post option in the GWE menus and get some idea what they mean and how they can differ from one controller to the next. This will give you a GWE machine profile to use when programming your controller. It's good to have a notion in the back of your mind that these differences exist. Go through each option on GWE's Post page and set the options up as your controller calls for. Set up another machine profile for your machine's controller.
You can use the GWE post options to look up what some of the possibilities are. If you have a CAM package. Many manual machinists are under the impression that CNC is only good for manufacturing multiple identical parts. This article is all about how. You can do anything on your CNC that the manual machinist can and often faster once you know how. Most manual machinists would see that as a tremendous improvement over Copyright by CNCCookbook. It just ain't so!
Good CNC machinists can do most anything a manual machinist can do and then some. A typical Fanuc panel you might use. But how does it work? There's way more knobs and buttons and no handwheels! Once you get used to the idea of using your CNC in that capacity.
What about those Power Feeds? There are two approaches. Those are DRO's. Select axis and speed then spin the wheel. A pendant for jogging a CNC. First of all. You generally select an axis. Jogging is where you're spinning a simulated electronic handwheel. By now you will have seen that the front panel of your CNC displays the X. See all those X.. CNC's have the ability to jog. It's pretty easy. It is a mode.
That tells the CNC to switch from rapids to linear interpolation. Check out this Mach3 Standard Mill home screen: Mach3 Standard Mill Screen Set. MDI is extremely useful to know your way around. It amounts to the same thing but you have a fine ability to control the speed the machine moves at using the "Feedrate" command.. Most CNC's come up with G00 active by default. You put your machine into MDI mode. You don't really need the machine to move at its fastest possible speed as a beginner--it just makes it easier for the machine to get away from you.
Look up in your operator's manual how to go about accessing MDI for your controller. When not running a program. I want you to ignore G00 and rapids when you MDI for the time being if you're just starting out. I'd like you to try to remember to perform a G01 command at the beginning of any session. So for example.
G00 some machines will accept G0 too tells the machine to expect rapids motion. Just to the left of them is the MDI typein field. Enter "M03" for clockwise rotation and your spindle should spin up to rpm in the clockwise direction. To make a move.
The spindle won't actually start to rotate until we ask it to because it doesn't know whether to go clockwise or counterclockwise. Let's allow even a little more than that to be sure the cutter clears the workpiece--after all. Pretty easy. You've got a workpiece 5" long in X.
If you don't. To start your spindle going. Practice moving the axes around with MDI. You've issued the "G01" and "F" words G-Code calls those letters "Words" and you're ready for the coordinates.
Think of M-Codes as "Miscellaneous" codes. If you're in inches. If you know the feedrate you want to do your cutting at. This means multiple axes move at rates so that they all get to the end coordinates you've specified at the same time. Let's say your cutter is all lined up for a face milling pass. Had we been doing it for real. While the whole language is commonly referred to as "G-Code".
Let's go for rpm by entering S in the MDI. If you don't need an axis to move from its current coordinate. So let's take time to learn a couple more codes. The machine will move using what's called "linear interpolation". Coolant is switched on using M08 for flood and M07 for mist or just air. What do you do? If you're not already in G01 mode. Now the axis motions will be a lot less scary and easier to manage.
Fanuc refers to M-Codes as "Auxilliary" functions. There are many more g. M13 and M Start Spindle and Coolant On some machines. Stop the spindle with M05 and coolant with M M13 starts the spindle running clockwise and M14 runs counterclockwise. These m-codes start the spindle and the coolant at the same time. You'll pick them up quickly with practice.. After all G00 and G01 don't exactly mean anything by themselves--they're pretty arbitrary. Now you've got the gist of using MDI.
The buttons to the right of "Insert" trigger the various code insertion Wizards. Don't worry. They remember all this for you so you don't have to remember the exact codes when you're writing a program. Just select the code you want or type its number. Each code is called out in the list with a description of what it does. Each code is called out with a description of what it does.. You can close and pop up a different Wizard or switch directly to G-Codes using the radio button at the top of the panel.
The G-Codes are grouped into categories by the buttons at the top to help you narrow your search. You can print it out to keep near the machine until you memorize them. There are a lot more handy capabilities in the Wizards that we'll be covering during the rest of this course. So far we have only considered G-Codes from the Motion category. G00 and G Another thing to note: G-Codes are grouped in categories. Linear Interpolation mode. If you're not so lucky.
Always think carefully about what's about to happen before hitting the Enter key to initiate the MDI command. Start out with small cheap endmills and leave the big expensive facemills and indexable tooling until you're sure you have the hang of it.
If you get confused. In fact. This is an easy way to go somewhere you didn't expect. Motion in a straight line at the G01 feedrate established by "F".
The bigger the tool. MDI is almost too easy. If you're lucky. You can change spindle rpm without issuing an M03 each time. Beware dropped digits and signs. Move the rotational axis to the specified angle. Here are some tips to try to cut down on the incidence of accidents with MDI: We're going to use G01 instead.
Once you're in the neighborhood. When a pilot is landing a plane. Use it to make a quick check as the cutter starts getting close to cutting--if distance to go is wildly greater than the amount you expect the cutter to have to move to finish your command.
Save MDI for feeding cuts. Use your pendant and jog. Don't hesitate to reach for it if you don't understand what's going on. Entering the workpiece or moving close to the workpiece requires the most vigilance. Give it your full attention. First because you'll move more slowly and second because you won't get confused about whether the machine is in G00 or G01 when you're first starting out. Visualize pressing it a couple of times. Before you issue an MDI. It's easier to let up if things start to get pear shaped on you.
Don't allow distractions while you're running the machine. Once you've mastered getting G01 to go where you want it to in GWE. Learn to use touch offs and an edge finder to precisely locate the tool just as you would with your manual machine. Get good at predicting what will happen. Watch what happens. Start with an empty file and issue your faux-MDI commands by just typing them into the text pane. Learn to make the cutter go where you want it to go. Start out with the spindle high above anything it might touch.
Load a piece of scrap material and a cutter and try some practice passes under MDI control. Check out G-Wizard Conversational to give it a try. If you don't know how to do this. For many. Even today the subject of whether CNC'ers need to learn Manual Machining will often provoke a strong debate back and forth.
If you drill down on the argument and ask why manual machining would be faster. Think of Conversational CNC whenever you have a relatively simple part that doesn't have a lot of features or features that involve complex curves and shapes.
With Manual Machining. Many believe that CNC is only good for making many parts or complex parts. For all those times when you would turn to a manual machine instead of a CNC because the overhead of the CADCAM cycle was going to mean you could do it faster manually. You don't have to tool your CNC in that way.
We've seen in our last chapter that with MDI. Lathes are particularly well suited to Conversational CNC. Another great application for Conversational CNC is secondary operations. The key is simplicity. They maintain that manual machining will be faster any time you're just making one relatively simple part. Now you can stick with the CNC and do the job even faster than the manual. This one is much closer to the mark. If you want to see some examples of how to program certain features in g-code.
Drill or Interpolate a hole. Conversational CNC is a quick way to turn them out. Face Mill: What you have to do is break your part down into these basic operations: It's quick and easy. Cut a rectangular or round boss. You've got some basics at the top: Tap a hole.
Do simple engraving As you can see. Cut a slot at any angle. Thread Mill: Thread Mill internal or external threads. Cut a rectangular or round pocket.
If you click one. Material Top Z: Cutting begins here and most CNC'ers like to make that value 0. Place the holes on an arc.
It will be fully documented with comments and ready to run. Where an endmill is used to make holes potentially much larger than the diameter of the endmill. Place the holes in a grid. If 0 is the top of the workpiece. Safe Z: This is the Z where the cutter can move freely without hitting anything. I usually make Safe Z 1" above. Make a circle of holes.
This is a powerful technique not available on Manual Machines! Having answered the questions. Place the holes in a line Lastly. I make this 0. Rapid to Z: This is the height where we can rapid down to there. Work Offset: Let's you use work offsets. Here is the graphical menu of lathe operations: You need to tell the Wizard which tools to use and whether to turn on Coolant. Give a list of hole coordinates.
Next is a set of options for positioning multiple holes: Put the hole at the Current Position. Custom cycle: A powerful deep hole drilling capability is provided here.
Via canned cycle. OD Turning and Tapers. ID Turning and Tapers. Here is the OD Turning Wizard for example: For some of these things you'd need special tooling such as a ball turning fixture. Using the Wizards is much like with the Mill Wizards. Conversational CNC is available from a lot of sources.
You'd never get the taper attachment set up or threading dialed in before the CNC was done. It is an option for many machine tools. You may find the videos in our G-Wizard University helpful to getting started. Give Conversational CNC a try.
We've mentioned before that there are lots of "Modes" in G-Codes. You only specify the coordinates that have actually changed.
The exact use of modes is one of the areas that differs from one G-Code Dialect to the next. Modes save time and make our g-code programs shorter.
People often think modally. There are many examples of modes in g-code. You don't always have to specify X. Get out the programming manual for your control and find at least one example of a modal g-code and one example of a one-shot g-code. A one-shot g-code is only in effect for the block it is used in. Speaking of things which are not modal.
Most of the one-shot g-codes are fairly advanced. Even if most of your g-code is produced via CAM software. Sometimes its faster just to fix these by editing the code rather than trying to get back into the CAM and "trick" it into not making the error.
These are all real simple examples. You can also quickly get to cases where a little hand programming might optimize a program quite a lot. Often these are simple errors. A couple of other case for hand working g-code: It's not hard to bring up the g-code in an editor and make the changes.
You can see it right in the g-code and delete it. He may have a bad post or some other problem. The part will be cut correctly. You want to adapt the program to the differences between controllers without rerunning the CAM against a different post-processor. There's a bunch of different cases where this can be really handy and productive.
Perhaps you can't quite get the CAM program to do things the way you want it to. There's also a whole class of simple g-code programs that can be created without recourse to CAM. Suppose the CAM programmer didn't account for the fixturing quite correctly. It's important more often than not to be able to do some hand tuning to the g-code. The list goes on. It's pretty easy to program by hand around those obstacles.
Let's leave aside the issue of writing g-code from scratch for a minute. I know a machinist whose CAM kicks out an errant move whenever it moves to a new work offset. You don't have the CAM any longer but need to be able to change the program.
A good CNC Editor is a handy thing to have on hand! Beyond those basics. Nothing wrong with that. These features determine how easy it is to edit the text of your program. Program Revision Features: The features help you to make mass revisions to your program. With the toolbar. The basics like clipboard support. Look for editors were you can accomplish most everything with either the keyboard or mouse so that you don't have to leave the keyboard if you don't want to.
G-Code Simulator and Backplotter Features: These features allow you to watch the g-code program execute in simulation. Find and Replace G-code programmers use find and replace a lot. They fall into these key categories. Before we get too far into the g-code specific features. Informational and Power Editing Features: These features give you extra power in understanding your program.
You're no doubt already used to some kind of editor. Keyboard Shortcuts Touch typists realize pretty quickly that having to jump back and forth between mouse and keyboard slows them down quite a bit.
N10 might be on the 1st physical line. Make sure your CNC Editor can append a file to the one being edited or insert it in place.
Not long after you'll be wanting to combine these files in various ways. Appending or Inserting another File After a while. Jump toolbar. Jumping in a G-Code Program G-code has a pretty regular structure. Informational and Power Editing Features Whether you're a beginner or an expert. It's nice to have an editor that can automatically capitalize outside the comments to save where and tear on the shift key as you're typing. Capitalization A lot of g-code is written in capital letters.
This comes up whether you're reading or writing g-code. This is helpful for learning the g-code as well as for getting a refresher on the details you may have forgotten. Hints View shows you a quick explanation of what the g-code does and it also shows error messages. Maybe you don't remember which G-Code is used for the peck drill cycle. N G03 X0. Let's take a close look at the Hint: The Hint for an Arc.
In bold at the top is the original text of the line. Line N has an arc. The Hint below the backplot tells all. Suppose you haven't learned arcs yet. This is useful if we're in Hints view and can't see the g-code line text.
It tells us the following: We see what the IJK values parse to be. The coordinates of the center of the arc are 0. You should take million as the tool will last a LOT longer! Because the numbers get silly after a while, I limit the results to be no more than times longer life. Chipload Adjustment: The value, in percent, by which to multiply chipload.
There is also a chipload adjustment available tool by tool in the Tool Crib. G-Wizard remembers all the profiles you create. It also remembers the profile you last selected in the Feeds and Speeds calculator and brings that up each time you restart G-Wizard. Editing a Profile To edit a profile, select it with the "Machine" dropdown menu, change whatever fields you like below, and press "Save".
Creating a New Profile A new profile is created any time you change "Name" to a name that didn't exist before and press "Save". Deleting a Profile To edit a profile, select it with the "Machine" dropdown menu, change whatever fields you like below, and press "Delete Machine".
Warning: You can't get it back and there is no "Undo"! Reverting to the Default Profiles To revert to the default profiles, press "Reset". Warning: This deletes any new profiles you may have created! Select which tool table you'd like to use from the Table choice.
If possible, make it the one that reflects the real tools in your changer or that you own. You can create new tables or delete tables. Eventually, you will associate tables with particular machines too, but this is not yet working. To edit a tool in the table, simply select it and press the "Edit Tool" button.
To create a new tool, press "New Tool". To delete a tool, press "Del Tool". The tools are saved when you exit G-Wizard to a settings file. Over on the Feeds and Speeds tab, if you want to choose from the Tool Crib "Default" Table instead of the generic list of tools, simply click on the "Crib" checkbox and the tool choices will be those of the "Default" table: Custom Tool Data From the Tool Crib's Tool Editor double click any tool crib entry , you can access custom tool data by clicking the "Cust.
Tool" button. Custom Tool Data lets you enter data to override the G-Wizard defaults. You can enter data on a material-by-material basis for a given combination of Vendor, Product, Vendors Tool , and Insert. For each of these combinations you can enter surface speed SFM and chipload IPT for the range of diameters that G-Wizard keeps in its internal database. Any number you don't change stays with the G-Wizard defaults. This saves you having to enter complete information for a tool when perhaps all you're interested in is one material and a few diameters.
Values that you customize are displayed in orange see the screen shot and defaults values remain black. To create or edit an entry, you must first get the right combination of Vendor, Product, Number, and Insert to display at the top. If it's already there from a previous visit, no worries.
If not, you can either Search to see if it already exists, or create a New entry if it doesn't. In Search, enter one or more values in "Vendor", "Product", or "Number" and press the "Search" button to see matching entries. In the screen shot, we've entered "MariTool" and gotten one match. To see valid values in the database, use the down arrow buttons on the right. It's best to work from top to bottom.
Pick "Vendor" first, then product and so on. If you just want to see all the entries in the database, leave all the Search entries blank and press the "Search" button. Once you have a list, click on one of them and select "OK" to choose that data.
If you save having cleared the fields, the tool will be certain to use G-Wizard default values. Note the following: If you "Reset" but don't "Clear", there is no custom tool data in the database, but your Vendor, Product Name, Id , and Insert information are still carried by the Tool Crib, unless you delete the tool carrying the information.
