parameter Change via Reaction
MP7415.1 Smooth contour transition
Input: %0000000x
0: = Do not smooth contour transition
1: = Smooth contour transition
Bit 1 reserved
Bit 2
1= jerk limit active
Bit 3
1 = short contour elements (< 16 µm) are
combined to form one contour element
Bits 4 to 7 reserved
MP7420.0 Cycles for milling pockets with combined
contours
Input:
%xxxx
Bit 0 Milling direction in channel milling
0 = pockets counterclockwise, islands
clockwise
1 = pockets clockwise, islands
counterclockwise
Bit 1 Sequence for clearing and channel-
milling
0 = first mill the channel, then clear the
pocket
1 = first clear the pocket, then mill the
channel
Bit 2 Merging of listed contours
0 = contours are combined only if the tool
center paths intersect
1 = contours are combined if the
programmed contours intersect

Bit 3 Clearing and channel-milling to pocket
depth or for each pecking depth
0 = each process uninterrupted to pocket
depth
1 = first channel milling, then clearing for
each pecking depth before proceeding
to the next depth.
Bit 4: Position after machining the cycle
0 = tool moves to same position as
before cycle was called
1 = tool moves only to the last
programmed position
