10.2 Part Families—Q Parameters in
Place of Numerical Values
The Q parameter function D0: 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
N150 D00 Q10 P01 +25* Assign
... Q10 contains the value 25
N250 G00 X +Q10* corresponds to G00 X +25
Cylinder radius R = Q1
Cylinder height H = Q2
Cylinder Z1 Q1 = +30
Q2 = +10
Cylinder Z2 Q1 = +10
Q2 = +50
