MP7420 Cycles for milling pockets with combined contours
Format: %xxxxx
Input: Bit 0 – Milling direction for channel milling:
0: Channel milling of the contours for pockets
counterclockwise, clockwise for islands
1: Channel milling of the contours for pockets
clockwise, counterclockwise for islands
Bit 1 – Sequence for rough-out and
channel milling:
0: First channel milling, then pocket rough-out
1: First pocket rough-out, then channel milling
Bit 2 – Merging of listed contours:
0: Contours are merged only if the
tool center paths intersect
1: Contours are merged only if the
programmed contours intersect
Bit 3 – Rough-out and channel milling to
pocket depth or for every infeed
0: Rough-out and channel milling
uninterrupted to pocket depth
1: For each process: first channel milling, then
rough-out depending on bit 1
Bit 4 – Position after completion of the cycle:
0: Tool moves to the same position as before the
cycle was called
1: Tool moves only in the tool axis to the
clearance height
