Fundamental Principles of NC Programming

Note

2.1

Name of an NC program

Rules for program names
Each NC program has a different name; the name can be chosen freely during program
creation, taking the following conditions into account:
• The name should not have more than 24 characters as only the first 24 characters of a
program name are displayed on the NC.
• Permissible characters are:
-
-
-
• The first two characters should be:
-
-
If this condition is satisfied, then an NC program can be called as subroutine from another
program just by specifying the program name. However, if the program name starts with a
number then the subroutine call is only possible via the CALL statement.
Examples:
_MPF100
SHAFT
SHAFT_2
