Any repetitive toolpath or machine activity is suitable to be developed as a subprogram.Īny subprogram has to have a number (for example O6001), in the same format as the main program (or other program of origin). The main advantages of subprograms include transportability between programs (even machines), shorter programs, and easier editing. For variable type subprograms - called macros - a special control option is required.
The content of standard subprograms is fixed and can be used only for the intended, specific purpose. Such repetition can take place in one program or in several programs. Subprograms (also known as subroutines), are specially designed programs that can be called on demand by another program and repeated as desired. This article reviews the use of three common methods which are subprograms, macros, and parametric programming. CNC programs use several techniques to allow the programmer to create complex pieces of code using CNC code building blocks.
