Cutting, longitudinal plunge—Expanded
Select
Roughing cycles lon/trans
Select Plunge longit.
Select the Expanded soft key
The cycle roughs the area described by the Start point contour ,
End point contour and Plunging angle , taking the oversizes into
account.
The tool plunges with the maximum possible angle,
leaving material remaining
The steeper the tool plunges into the material, the
greater the feed rate decrease (max. 50 %)
Cycle parameters:
