Part families—Q parameters in place
of numerical values
Application
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
N150 D00 Q10 P01 +25*
Assign
...
Q10 is assigned the value 25
N250 G00 X +Q10*
Corresponds to G00 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
