Overview of User Macro Programs in Precision Parts Processing

1. Definition of User Macro Programs

In precision machining of parts, user macro programs are special programming functions in FANUC CNC systems and similar products.

The so-called user macro program is essentially similar to a subroutine. It also stores a set of instructions that implement a certain function in the system memory in the form of a subroutine, and executes this function by calling the instructions through the macro program. 5 Axis Mill For SaleIn the main program, these functions can be implemented as long as the corresponding calling instructions are included.

In precision machining, a set of programs stored in the form of sub programs with variables is called a user macro program. Called macro program; The instruction that calls a macro program is called a "user macro program command" or a macro program usage instruction.5 Axis Mill For Sale

2.The difference between user macro programs and general programs

Compared with regular programs, macro programs have program words that are constants, and a program product can describe a geometric shape, so they lack flexibility and applicability. In the user macro program ontology, 5 Axis Mill For Salevariables can be used for programming, and macro instructions can be used to assign values, perform operations, and other processing on these variables, so that macro programs can be used to perform actions with regular changes.5 Axis Mill For Sale

3. Classification of user macro programs

User macro programs are divided into two types: A and B. 5 Axis Mill For SaleIn some older FANUC systems (such as FANUC-OMD), A-class macro programs are used, while in more advanced systems (such as FANUC-0i), B-class macro programs are used.
