Would you like a handy cheat sheet that tells you everything you need to know to do quick and dirty CNC Tasks? G-Code Cheat Sheet. We talked a bit about CAM Software already. Our very own G-Wizard Editor is once such program. You could use a Notepad or some similar text editor. One of the best things about our G-Wizard Editor is it gives you hints in plain English that tell you what each line of g-code does. The hint appears right below the backplot:.
For example, lines of g-code are often numbered. What a pain it is to renumber by hand, but the g-code editor can do that for you automatically. Simulators may also be called Debuggers, Backplotters or Viewers.
Their role is the same. You can see the graphical backplot of the toolpath in the G-Wizard Editor screen shot above. You can tell at a glance from a backplot exactly what moves the tool will make when the program is run. A very high quality simulator like the one in our G-Wizard Editor , has a more capabilities than just a backplot:. If your CAM program includes a true CNC g-code simulator, then yes, it does have a simulated backplot and by all means use it.
They just plot the same geometry information that was used to create the g-code output by the postprocessor. This allows for subtle bugs to creep in that are not detectable in the CAM backplot. For a really deep dive on CNC Simulators, check out our article. What if you just want to make a simple rectangular bracket with 4 holes? What if you need to turn a little spacer on your lathe? Do you really need the full power and complexity of those things to get those simple jobs done?
No, of course not.
Conversational Programming is built right in to G-Wizard Editor…. Answer a few questions, push a button, and you get g-code to do the job. To learn more about Conversational Programming, check out our in-depth article.
They will all save you time. It only takes a few seconds to check the code when it comes out of CAM, and it can surely save you some time. Why be without it? One of the key things to understand is where Part Zero is going to be. Your CAD program has some sort of coordinate system, and your part is positioned in the drawing relative to that coordinate system.
Perhaps you stuck the part well away from the 0, 0, 0 origin in the CAD program so it would be easier to see without the axis lines being too close. Later on we can get all fancy with Work Offsets and other ways of transforming the coordinates, but when you first start the machine, think of X0 Y0 Z0 as Part Zero. There are a lot of different theories on where to put Part Zero, and it matters for how easy and natural your CNC work will be.
When milling, a lot of emphasis is on the Z axis. This facilitates knowing when your cutter is cutting workpiece and when it is cutting air. For example, it might be the top of a vise jaw. This is handy should you need to remove your part for some reason. The exact coordinates of the top of such material will vary from workpiece to workpiece because sawing is not a precision operation. Cookbook Recipe: I like to use a Part Zero that corresponds to the fixed jaw of my vise when I will use a vise for machining.
Once you get used to making your CAD drawings with that in mind, it means you can walk up to the machine, stick a piece of material in the vise, load a g-code program designed with that notion of Part Zero, and immediately begin machining after just homing the machine. Since the vise generally stays put on the machine, there are no touch offs required, which is a nice productivity booster.
If I do need to move the vise or change jaws, no worries, I can just rezero on that location again. Whatever you decide to use for your Part Zero, you need to be aware of it, and it is worth thinking about how to choose a Part Zero that might save you a little time or make things easier to understand.
Machine Zero is the origin of the coordinate system that corresponds to the machines axis travels. When you setup the job, you will use edge finders or other sensors to tell the machine exactly where Part Zero is. This is a fixed coordinate system that is baked into the machine. If you crash or emergency stop, it can also be a good idea to home the machine so it can pick up its lost position. For that reason, Part Zero may also be called Work Zero. You can establish Work Coordinates in a variety of ways.
You also have the ability to establish multiple Work Coordinate systems, which is convenient for a lot of reasons.
There are lots of ways to do Touch Offs. Each has varying accuracy and requires you to work on your technique a bit. The Old School method uses paper—cigarette rolling papers were very thin and commonly available.
Use a little dab of oil to hold the paper in place and slowly jog the spinning cutter until it moves the paper.
The cutter is now located at the Zero, with the exception of the thickness of the paper. Some trial cutting and a micrometer will establish what that is. Be sure to use the same kind of paper each time so the thickness is repeatable. A more modern and accurate method would involve the use of a gage block. Gage blocks are precision machined to a very high tolerance and will include an inspection report that tells how much error there is in the block.
Instead, move the cutter up, stop moving, and try to slide the gage block between the cutter and the workpiece. At some point, you will have jogged the machine a little too far and can jog back until you can slide between the two. In fact, from many standpoints, a cylinder or ball shape large ball bearings are precise too! This is an important operation, so make sure you know how to do it on your controller. Your controller will have a way for you to enter an arbitrary value in and tell it that is where the tool tip is currently located.
These are tools that make it quick and easy to find the edge of some object so you can Zero on it. And here is a demonstration of a Haimer 3D Taster:. A probe can be the ultimate in convenience for doing these kinds of Zeroing operations.
Here is a Renishaw probe setting up work offsets:. Renishaw probe setting up work offsets on a VMC…. Each of these tools is similar in purpose, just with increasing capability, automation, and expense.
There are a wide variety of other tools available for precisely locating features on your parts and workpieces. Some are more specialized, such as the Blake Coaxial Indicator, which is used to locate bore centers.
Look up how to read Machine Coordinates versus Work Coordinates on the control panel too. Try some touch offs on your machine. Use the corner of a piece of scrap stuck in a vise for starters until you get good at it. If you have an edge finder, 3D Taster, or probe, give it a try as a way of precisely locating part zero. You can make the CNC do anything a manual machinist can do on a manual machine. Next up is perfecting your skills by learning the remaining basic techniques.

Try It! Chapter 2 G-Code Standards and Dialects: Chapter 3 CNC Coordinates: Extended Resource List. What is G-Code? What are the different methods of CNC Programming? CNC Machines are programmed using one of three methods: You should not be suprised to learn that many are quite proficient with G-Code: In general, G-Code Programming is ideal for these kinds of tasks: Simple parts can be easier with g-code than CAM. You want a rectangular cover plate with 4 holes in it.
For all those cases where you thought manual machining was faster, g-code or Conversational CNC will make the CNC machine an even better choice. Additionally, many machines support operator overrides for both rapid and feedrate that can be used to reduce the speed of the machine, allowing operators to stop program execution before a crash occurs.
For educational purposes, line numbers have been included in the program above. They are usually not necessary for operation of a machine, and increase file sizes, so they are seldom used in industry. However, if branching or looping statements are used in the code, then line numbers may well be included as the target of those statements e.
GOTO N Some machines do not allow multiple M codes in the same line. Programming environments[ edit ] This section possibly contains original research.

January Learn how and when to remove this template message G-code's programming environments have evolved in parallel with those of general programming—from the earliest environments e.
G-code editors are analogous to XML editors , using colors and indents semantically [plus other features] to aid the user in ways that basic text editors can't.
Two high-level paradigm shifts have been 1 abandoning "manual programming" with nothing but a pencil or text editor and a human mind for CAM software systems that generate G-code automatically via postprocessors analogous to the development of visual techniques in general programming , and 2 abandoning hardcoded constructs for parametric ones analogous to the difference in general programming between hardcoding a constant into an equation versus declaring it a variable and assigning new values to it at will; and to the object-oriented approach in general.
Macro parametric CNC programming uses human-friendly variable names, relational operators , and loop structures, much as general programming does, to capture information and logic with machine-readable semantics. Whereas older manual CNC programming could only describe particular instances of parts in numeric form, macro programming describes abstractions that can easily apply in a wide variety of instances.
The difference has many analogues, both from before the computing era and from after its advent, such as 1 creating text as bitmaps versus using character encoding with glyphs ; 2 the abstraction level of tabulated engineering drawings , with many part dash numbers parametrically defined by the one same drawing and a parameter table; or 3 the way that HTML passed through a phase of using content markup for presentation purposes, then matured toward the CSS model.
In all these cases, a higher layer of abstraction introduced what was missing semantically. STEP-NC reflects the same theme, which can be viewed as yet another step along a path that started with the development of machine tools, jigs and fixtures, and numerical control, which all sought to "build the skill into the tool. Those efforts were fine for huge corporations like GM and Boeing. Any machine tool with a great number of axes, spindles, and tool stations is difficult to program well manually.
It has been done over the years, but not easily. This challenge has existed for decades in CNC screw machine and rotary transfer programming, and it now also arises with today's newer machining centers called "turn-mills", "mill-turns", "multitasking machines", and "multifunction machines".
However, it is currently only in some contexts that manual programming is obsolete. Plenty of CAM programming takes place nowadays among people who are rusty on, or incapable of, manual programming—but it is not true that all CNC programming can be done, or done as well or as efficiently, without knowing G-code. Efficiently written G-code can be a challenge for CAM software.
Ideally a CNC machinist should know both manual and CAM programming well, so that the benefits of both brute-force CAM and elegant hand programming can be used where needed. Many older machines were built with limited computer memory at a time when memory was very expensive; 32K was considered plenty of room for manual programs whereas modern CAM software can post gigabytes of code.
CAM excels at getting a program out quick that may take up more machine memory and take longer to run. This often makes it quite valuable to machining a low quantity of parts. But a balance must be struck between the time it takes to create a program and the time the program takes to machine a part. It has become easier and faster to make just a few parts on the newer machines with lots of memory.
