Program structure

Structure and content
The NC program consists of a sequence of blocks (see the table below). Each block
represents a machining step. Instructions are written in the blocks in the form of words. The
last block in the execution sequence contains a special word for the end of the program, for
example, M2.
The table below shows you an example of the NC program structure.
