Cycle parameters (second input window)
 P infeed depth —default: Total depth in one infeed
 U overlap factor
„ No input: Contour milling
„ U>0: Pocket milling—(minimum) overlap of milling paths =
U*milling diameter
 I contour-parallel oversize
 K oversize in infeed direction
 FZ infeed rate —default: Active feed rate
 E reduced feed rate for circular elements—default: Active feed rate
 H cutting direction —default: 0
„ H=0: Up-cut milling
„ H=1: Climb milling
 J contour milling (default: 0) depending on "U," the following
applies:
„ Pocket milling and J=0: On the contour
„ Pocket milling and J=1: Inside
„ Pocket milling and J=2: Outside
„ Contour milling and J=0: From the inside towards the outside
„ Contour milling and J=1: From the outside towards the inside
 O roughing/finishing: Milling sequence (only for pocket milling)—
default: 0
„ O=0: Roughing
„ O=1: Finishing
 R approaching radius: Radius of approaching/departing arc—
default: 0
„ R=0: Contour element is approached directly; feed to starting
point above the milling plane—then vertical plunge.
„ R>0: Tool moves on approaching/departing arc that connects
tangentially to the contour element.
„ R<0 for inside corners: Tool moves on approaching/departing arc
that connects tangentially to the contour element.
„ R<0 for outside corners: Length of linear approaching/departing
element; contour element is approached/departed tangentially.
