Parameters
Parameter Data type Description
NPP STRING Name of contour subroutine
MID REAL Infeed depth (enter without sign)
FALZ REAL Finishing allowance in the longitudinal axis (enter without sign)
FALX REAL Finishing allowance in the transverse axis (enter without sign)
FAL REAL Finishing allowance according to the contour (enter without sign)
FF1 REAL Feedrate for roughing without undercut

FF3 REAL Feedrate for finishing
VARI REAL Machining type
Range of values: 1 ... 12
TT REAL Dwell time fore chip breaking when roughing
DAM REAL Path length after which each roughing step is interrupted for chip
breaking
_VRT REAL Lift-off distance from contour when roughing, incremental (to be
entered without sign)
Function
Using the rough turning cycle, you can produce a contour, which has been programmed in a
subroutine, from a blank by paraxial stock removal. The contour may contain relief cut
elements. It is possible to machine contours using longitudinal and face machining, both
externally and internally. The technology can be freely selected (roughing, finishing,
complete machining). When roughing the contour, paraxial cuts from the maximum
programmed infeed depth are programmed and burrs are also removed parallel to the
contour after an intersection point with the contour has been reached. Roughing is
performed up to the final machining allowance programmed.
Finishing is performed in the same direction as roughing. The tool radius compensation is
selected and deselected by the cycle automatically.
