4.10 Front and Rear Face Contours
Starting point of front/rear face contour G100-Geo
G100 defines the starting point of a front or rear face contour.
Line segment in front/rear face contour G101-Geo
G101 defines a line segment in a contour on the front face/rear face.
Parameters
X Starting point in polar coordinates (diameter)
C Starting point in polar coordinates (angular dimension)
XK Starting point in Cartesian coordinates
YK Starting point in Cartesian coordinates
Parameters
X End point in polar coordinates (diameter)
C End point in polar coordinates (angular dimension)
XK End point in Cartesian coordinates
YK End point in Cartesian coordinates
A Angle to positive XK axis
B Chamfer/rounding. Defines the transition to the next contour
element. When entering a chamfer/rounding, program the
theoretical end point.
„ No entry: Tangential transition
„ B=0: No tangential transition
„ B>0: Rounding radius
„ B<0: Chamfer width
Q Point of intersection. End point if the line segment intersects
a circular arc (default: 0):
„ Q=0: Near point of intersection
„ Q=1: Far point of intersection
Programming
„ X, XK, YX: Absolute, incremental, modal or “?”
„ C: Absolute, incremental or modal
