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
 BS<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.
Direct contour definition parameters for recessing operations
X1, Z1 Contour starting point
X2, Z2 Contour end point
RC
Rounding: Radii in the recess base
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
