Sequence
Position reached prior to cycle start:
The starting position is any position from which each of the long holes can be approached without collision.
The cycle creates the following sequence of motions:
●
Using G0, the starting position for the cycle is approached. In both axes of the current plane, the next end point of the
first slot to be machined is approached at the height of the retraction plane in this applicate, and then the applicate is
lowered to the reference plane brought forward by the safety clearance.
●
Each long hole is milled in a reciprocating motion. The machining in the plane is performed using G1 and the feedrate
programmed under FFP1. The infeed to the next machining depth calculated using G1 internally in the cycle and using
feedrate is performed at each reversal point until the final depth is reached.
●
Retraction to the retraction plane using G0 and approach to the next long hole on the shortest path.
●
After the last long hole has been machined, the tool is moved with G0 to the position in the machining plane, which was
reached last and which is specified in the diagram below, and the cycle is ended.
Explanation of the parameters
For an explanation of the parameters RTP, RFP, and SDIS, refer to Section "Drilling, centering - CYCLE81 (Page 126)".
DP and DPR (long hole depth)
The depth of the long hole can be specified either absolute (DP) or relative (DPR) to the reference plane.
With relative specification, the cycle calculates the resulting depth automatically using the positions of reference and
retraction planes.
