You can carry out mathematical calculations with variables, adding, subtracting, simple trigonometry etc. What are the winning numbers on tonight’s lottery? You can interrogate the control for example: There are a lot of advantages to using a basic CNC Macro Programming.ġ.When you prove it out the first time you know the positions will be correct for the second time.ģ.You can change your mind without too much code alteration.Ĥ.Sorry I can’t think of a number 4 but 3 advantages didn’t look enough.Īs you get more and more into macro programming you start to realise the massive potential it unlocks. Here is the program as CNC Macro Programming So, each time the sub-program is called it will look to see what is in variable 1 and variable 2 Here is the program as it would be normally ![]() So you can see that in the sub-program the depth and the feed-rate are defined as variables. The second time we want a depth of 15mm and a feed-rate 200mm/min. The first time we call the sub program we want a depth of 5mm and a feed-rate of 100mm/min. When we use macro programming we use a sub program. Initially we are just using a cycle to spot drill and then another cycle to drill. The macro programming example shown is for drilling some holes. You can use a variable to replace any number in a program and then define its value externally. I would hate you to read the whole of this very boring article only to find you can’t do any of the stuff I am talking about.Ī bit like reading the manual for your car only to find you bought the one with the small engine and you can’t actually get from 0-60 in under 8 seconds.

If you have a touch probe on your CNC machine you almost definitely will have the use of macro programming. Most modern controls have this kind of functionality as standard so you might think why would I need to learn macro programming. Historically macro programming was used for things like bolt hole circles and cycles that machines didn’t have built in. Macro programming uses the #(variable) sign to represent values. In fact the use of macro programming in its simplest form is very easy and the rest is shrouded bullshit. It means you are controlling a program by external parameters. Macro programming is sometimes known as parametric programming. You can always ask an expert in the Excel Tech Community or get support in the Answers community.CNC Macro Programming an Introduction Book Now CNC Macro Programming CourseĬNC Macro programming is sometimes thought of as a bit of a black art in CNC programming.
