Clearance cycle group
Plunge longitudinal
Plunge transverse
Roughing (expanded): The cycle machines the defined area, taking
the optional contour elements into account.
Finishing (expanded): The cycle finishes the defined contour section,
taking the optional contour elements into account.
Information on cycle parameters:
R:
Rounding (on both sides of the contour valley)
B1, B2: Chamfer or rounding (B1 contour start; B2 contour end)
• B>0: Rounding radius
• B<0: Chamfer width
Roughing:
• The cycle does not take oversizes into account in normal mode.
• The steeper the tool plunges into the material, the greater the
feed rate decrease (maximum: 50%).
Finishing:
• In the normal mode the tool returns to the “start point X, Z“.
• In the expanded mode the tool remains at the cycle end posi-
tion.
Danger of collision!
• If the setup and tip angles of the tool have not been de-
fined, the tool plunge-cuts at the plunging angle.
• If the setup and tip angles of the tool have been defined, the
tool plunge-cuts at the maximum possible angle. In this case,
the resulting contour will not be completely finished and may
need to be reworked.
