Cycle run:
1 Starting position (X, Z, C) is the position before the cycle begins
2 Calculates the number of cuts (infeeds to the milling planes,
infeeds in the milling depths) and the plunging positions and
paths for reciprocating or helical plunges.
3 Approaches to safety clearance and, depending on O, feeds
to the first milling depth or approaches helically or on a
reciprocating path
4 Mills a plane
5 Retracts by the safety clearance, returns and cuts to the next
milling depth
6 Repeat steps 4 and 5 until the complete area is milled.
7 Returns to Return plane RB
You can change the cutting direction with the cutting direction
H, the machining direction Q and the direction of tool rotation.
