Milling Cycles
3.9 Milling rectangular pockets – POCKET3
Programming example
Pocket
With this program you can machine a pocket that is
60mm long, 40mm wide, 17.5mm deep in the XY plane,
and which has a corner radius of 8mm. The angle in
relation to the X axis is 0 degrees. The final machining
allowance of the pocket edges is 0.75mm, 0.2mm at the
base, the safety distance in the Z axis, which is added
to the reference plane, is 0.5mm. The center point of
the pocket lies at X60 and Y40, the maximum depth
infeed is 4mm.
Up-cut milling uses the spindle rotation direction as
direction of machining.
Only roughing is to be performed.
