Fundamental principles of NC programming

10.1.1

Program names

Each program has its own program name. The name can be freely chosen during program
creation, taking the following conventions into account:
● The first two characters must be letters.
● Use only letters, digits or underscore.
● Do not use delimiters (see Section "Character set").
● The decimal point must only be used for separation of the file extension.
● Do not use more than 27 characters.
Example: WORKPIECE

Program structure

Structure and content
The NC program consists of a sequence of blocks (see 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 program:
e.g. M2.
