4.10 Extended stock removal cycle - CYCLE950 (SW 5.3 and later)
Programming example 2
A simple inside contour is to be machined on the same
part as in sample program 1.
A center bore is made first using a diameter-10 drill.
Then, the inside contour is roughed parallel to the
contour, since the hole roughly corresponds to the end
contour.
This is done by defining a blank contour again for inside
machining.
The stock removal contour is located in the same
program as the cycle call in the blocks N400 to N420,
the blank contour in blocks N430 to N490.
