Direct contour definition parameters for turning operations
EC
Type of contour
 0: Normal contour
 1: Plunging contour
X1, Z1 Contour starting point
X2, Z2 Contour end point
RC Rounding: Radius of contour corner
AC Start angle: Angle of the first contour element
(range: 0° < 90°)
WC End angle: Angle of the last contour element
(range: 0° < 90°)
BS –Chamfer/+radius at start:
 BS>0: Radius of rounding arc
 BS<0: Section length of chamfer
BE –Chamfer/+radius at end:
 BE>0: Radius of rounding arc
 BE<0: Section length of chamfer
BP Break duration: Time span for interruption of the feed. The
chip is broken by the (intermittent) interruption of the feed.
BF Feed duration: Time interval until the next break. The chip is
broken by the (intermittent) interruption of the feed.
