You can write g-code that just does the same thing over and over. It even shows you what modes are in effect, what macro variables are being accessed, and what their values are. Simulator Instrument Cluster shows you what the machine is doing.G-Code Hints: G-Wizard Editor will readback the line of g-code in plain English, adding tons of additional information.Transport cluster lets you run your CNC Macro Program simulation:Ĭhange speed, jump ahead to the interesting parts, rewind to see it again, vary playback speed, and more.Graphical backplot makes it easy to see what the tool motions are:.Handles the Fanuc Macro B syntax, the most widely used CNC Macro Programming syntax in the world.Here’s just a smattering of the specific features it has that are a tremendous help when CNC Macro Programming: Our G-Wizard Editor is the perfect tool for anyone wishing to do CNC Macro Programming. As such, any tool that will make it easier to understand what the g-code is doing and even to test it by simulation before you put it on your CNC machine is very helpful. G-Wizard Editor for CNC Macro ProgrammingĬNC Macro Programming makes for more complex g-code. But before we do that, let me tell you about a tool that will help you tremendously in learning and in doing CNC Macro Programming. Let’s give a brief overview of what each one means and how they fit together, then we’ll turn you loose to go through each lesson in more detail. CNC Macro Programming Topic AreasĬNC Macro Programming may be broken down into the following topic areas, and we have a lesson for each area: Just use a our G-Wizard CNC Simulator and Editor to play with the Macro B capabilities. If you don’t have a controller with Macro B, it’s still worth checking it out. We can’t document every G-Code Dialect here, but the concepts offered in Macro B will be similar to what you see elsewhere, and therefore applicable to those cases with slightly different syntaxes and capabilities. Not all controllers support full Macro B, and there are variations supported by some non-Fanuc controllers. A word about Fanuc Macro Bįanuc Macro B is by far the most common Macro Programming Dialect. Go through our lessons so you can add this power tool to your tool box. There are many more examples in the article, but you get the idea how powerful CNC Macro Programming can be. Using the G10 g-code, you can make part programs set themselves up for particular fixtures that will be at know locations on your fixture plate. Modular Fixturing can save you a lot of time by ensuring repeatability of where fixtures are located relative to machine coordinates. Just another job for cnc macro programming. Put it into a subprogram so it can be shared across all your g-code and then call that subprogram as needed. Suppose you have put together a really sophisticated strategy for deep hole drilling. Being able to quickly and flexibly change lot sizes or partially remachine parts to rework mistakes can be very helpful. You could use cnc macro programming to tell the part program how many of the available fixture slots actually contain parts and which of a series of machining steps to execute. Make it easier to rework parts or change lot sizes.By putting the feeds and speeds in macro variables, it becomes possible for the same program to work on all three materials. Perhaps you offer aluminum, stainless steel, and titanium, or some such. Suppose you make the same part, but in different materials. Adjust Feeds and Speeds for material variations.Here are just a few ideas from the article: We’ve prepared an article, 37 Things Your CAM Won’t Do For You That GCode Programming Can, that tells all about the potential things you might do with CNC Macro Programming. With CNC Macro Programming, a vast number of new things are possible. That’s useful, but computers and CNC controllers are capable of a lot more. Without CNC Macro Programming, G-Code is not really a full fledged computer language, it’s more a recording of a series of manual steps. It offers the most flexibility and the greatest potential power of any of the G-Code Programming Techniques. In many ways, Macro Programming is the highest level of G-code Programming. The next several lessons in the g-code tutorial provide a Mini-Tutorial on CNC Macro Programming and Fanuc Macro B.
