MP7420 Bit 2 = 0 (entry +0):
The control clears out the pockets separately, since the tool center paths do not intersect.
Material will remain in inside corners.
MP7420 Bit 2 = 1 (entry +4):
The control clears out the pockets jointly, since the programmed contours overlap. No material will
remain in inside corners.
MP7420 Cycles for milling pockets with free programmed contours.
Input range: 0 to 15
Bit 0 Direction for channel milling + 0 = Anti-clockwise channel milling of the pocket
contours, clockwise for islands
+ 1 = Clockwise channel milling of the pocket
contours, anti-clockwise for islands
Bit 1 Sequence for clearing + 0 = First channel milling, then clear out pocket
and channel milling + 2 = First clear out pocket , then channel milling
Bit 2 Merge programmed + 0 = Contours merged only if the tool center paths
contours intersect
+ 4 = Contours merged if the programmed contours
overlap
Bit 3 Clearing out and channel + 0 = Clearing out and channel milling performed in
milling to pocket one operation for all depths
depth, or for each + 8 = For each peck, first perform channel milling,
infeed depth and then clearing out (depending on Bit 1)
before next peck
