Programming

8.1 Fundamental principles of NC programming
8.1.1 Program names
Each program has its own program name. The name can be freely chosen during program
creation, taking the following conventions into account:
S The first two characters must be letters;
S Use only letters, digits or underscore.
S Do not use delimiters (see Section "Character set").
S The decimal point must only be used for separation of the file extension.
S Do not use more than 25 characters.
Example: FRAME52
8.1.2 Program structure
Structure and contents
The NC program consists of a sequence of blocks (see Table 8-1).
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:
M2 .
