4.4 Roughing Cycles
ICP contour-parallel, longitudinal/transverse
Call the "Roughing, longitudinal/transverse" cycles.
Select "ICP contour-parallel, longitudinal" (see figures
at right).
Select "ICP contour-parallel, transverse" (see figures
on the following page).
The cycle machines parallel to the contour, depending on the J
parameter:
J=0: The area defined by X, Z and the ICP contour, taking the
oversizes into account.
J>0: The area defined by the ICP contour (plus oversizes) and the
“workpiece blank oversize J.”
Cycle parameters
X, Z starting point
P infeed depth
—the infeed depth is determined taking J into account:
J=0: P is the maximum infeed depth. The cycle reduces the infeed
depth if the programmed infeed is not possible in the transverse
or longitudinal direction due to the cutting geometry.
J>0: P is the infeed depth. This infeed is used in the longitudinal
and transverse directions.
I, K oversize X, Z
N ICP contour number
J workpiece blank oversize—the cycle machines:
J=0: From the current tool position.
J>0: The area defined by the workpiece blank oversize.
T tool number
S spindle speed / cutting speed
F feed per revolution
Danger of collision!
If the tool angle and the tool point angle have not been
defined, the tool plunge-cuts at the plunging angle. If the
tool and point angles have been defined, the tool plunge-
cuts at the maximum possible plunging angle. In this
case, the resulting contour will not be completely
finished and may need to be reworked.
For workpiece blank oversize J>0: Set the “infeed
depth P” to the smaller infeed, if the maximum infeed
differs for the longitudinal and transverse directions due
to the cutting geometry.
