ú
Set-up clearance Q6 (incremental value):
Distance between tool tip and workpiece surface
ú
Clearance height Q7 (absolute value): Absolute height
at which the tool cannot collide with the workpiece
(for intermediate positioning and retraction at the end
of the cycle)
ú
Inside corner radius Q8: Inside „corner“ rounding
radius; entered value is referenced to the tool
midpoint path
ú
Direction of rotation ? Clockwise = -1 Q9: Machining
direction for pockets
■
Clockwise (Q9 = -1 up-cut milling for pocket
and island)
■
Counterclockwise (Q9 = +1 climb milling for pocket
and island)
You can check the machining parameters during a program
interruption and overwrite them if required.
