10 Programming: Q Parameters
254
10.2 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
15 FN0: Q10 = 25 ASSIGN:
... Q10 contains the value 25
25 L X +Q10 Means L X +25
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
Cylinder radius R = Q1
Cylinder height H = Q2
Cylinder Z1 Q1 = +30
Q2 = +10
Cylinder Z2 Q1 = +10
Q2 = +50
