Number of revolutions during dwell at spot-
faced hole bottom for inversed spot-facing
Program type M
Conditions Immediate
D40
Unit 1 revolution
Setting range 0 to 9
Z-axis feed dwell time at the spot-faced hole bottom in an inversed spot
facing cycle. Set this time in spindle revolutions.
When the inversed spot-facing tool
reaches the hole bottom, firstly the
Z-axis will stop moving until the
spindle makes D40 revolutions, and
then the rotational direction of the
spindle will reverse.
MPL023
R-point height during point-machining
Program type M
Conditions Immediate
D41
Unit 1 mm/0.1 inch
Setting range 0 to 99
R-point height of each tool in the point-machining unit
Example:
MPL024
R-point
Machining surface
Initial point
D41
Note:
For the inversed spot-facing unit or the back-boring unit, this parameter
can also be used for setting the clearance amount at the hole bottom.
