11.2 Part Families—Q Parameters in
Place of Numerical Values
The Q parameter function FN0: ASSIGN assigns numerical values to
Q parameters. This enables you to use variables in the program
instead of fixed numerical values.
Example NC blocks
You need write only one program for a whole family of parts, entering
the characteristic dimensions as Q parameters.
To program a particular part, you then assign the appropriate values to
the individual Q parameters.
Example
Cylinder with Q parameters
15 FNO: Q10=25

...
Q10 is assigned the value 25
25 L X +Q10
Means L X +25
