The next chapter will delve into how to divide your code up into subprograms and access the subprograms. In this chapter, we’ll be dealing with variables and formulas. Almost anything is possible.Ĭovering the whole of parameterized programming will involve three chapters in our tutorial. A custom drilling cycle, or perhaps a routine to automatically serial number your parts. Imagine being able to create your own custom canned cycles that can do almost anything. You’ll be able to create general purpose routines that use parameters to tie them to specific uses you want to make. Once you have variables, you can start to parameterize your programming. A tremendous amount can be accomplished in that way, but just as algebra is more powerful than arithmetic, so parameterized programming is more powerful than basic g-code, and for the same reasons. If we wanted to go to a particular coordinate, we had to enter that coordinate, either absolute or relative, to get there. Until now, all of our g-coding has been done without any recourse to variables or formulas. 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. That’s useful, but computers and CNC controllers are capable of a lot more. Without 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 tutorial stand together as a Mini-Tutorial on Macro Programming and Fanuc Macro B. Mastering them is pretty easy and they’ll give you tremendous power and control in your g-code programming. They’re just buzzwords and jargon that stand for some pretty simple concepts.
