MP Function and input
MP7410 Scaling cycle in two or three axes
Input:
MP7411 Tool data in the touch probe block
Format:
Input:
MP7420 Cycles for milling pockets with combined contours
Format:
Input:
MP7430 Overlap factor for pocket milling
Input:
4 – 58
0: Scaling cycle is effective in all three
principal axes
1: Scaling cycle is effective only in the
working plane
%xx
Bit 0 –
0: The calibrated data of the touch probe
is used.
1: The current tool data from the
last TOOL CALL is used
Bit 1 –
0: Only one set of touch probe calibration data
1: More than one set of touch probe calibration
data are managed in the tool table
%xxxxx
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
0.001 to 1.414
