The cycle creates the following sequence of motions:
● Approach of the position at the beginning of the cycle indicated in the SLOT1 sequence illustration with G0.
● Complete machining of a slot is carried out in the following steps:
– Approach of the reference plane brought forward by the safety clearance by using G0
– Infeed to the next machining depth with G1 and with feedrate value FFD
– Solid machining of the slot to the finishing allowance at the slot edge with feedrate value FFP1. Then finishing with
feedrate value FFP2 and spindle speed SSF along the contour according to the machining direction programmed
under CDIR.
– The depth infeed is always carried out at the same position in the machining plane until the end depth of the slot is
reached.
● Retract tool to the retraction plane and move to the next slot with G0.
● After the last slot has been machined, the tool is moved with G0 to the end position in the machining plane, which is
specified in the diagram below, and the cycle is ended.
