7 Programming with Q Parameters
7.8 Examples for Exercise
Bolt hole circles
Bore pattern 1 distributed over a full circle:
Entry values are listed below in program blocks
N10 to N80.
Movements in the plane are programmed
with polar coordinates.
Bore pattern 2 distributed over a circle sector:
Entry values are listed below in blocks N150 to
N190; Q5, Q7 and Q8 remain the same.
The holes are executed with cycle G83:
