1.2 Program structure.
A CNC program consists of a set of blocks or instructions that properly organized, in
subroutines or in the program body, provide the CNC with the necessary data to machine
the desired part.
Each block contains all the functions or command necessary to execute an operation that
may be machining, preparing the cutting conditions, controlling the elements of the machine,
etc.
The CNC program may consist of several local subroutines and the body of the program.
The local subroutines must be defined at the beginning of the program.
