Programming example
Row of holes
With this program you can machine a row of holes of
five tapped holes positioned in parallel to the Z axis
on the ZX plane, with a distance between each hole of
20mm. The row of holes starts at Z20 and X30, the first
hole in the row being 10mm from this point. The
geometry of the row of holes is described by the cycle
HOLES1. First of all, drilling is performed with cycle
CYCLE81 and then with CYCLE84 tapping (rigid). The
holes are 80 mm deep. This is the difference between
the reference plane and the final drilling depth.
