4.7 Front/Rear face contours
Starting point of front/rear face contour G100-Geo
G100 defines the Start point of a front or rear face contour.
Parameter:
X: Start point (polar)
C: Start angle (polar angle)
XK: Start point (Cartesian)
YK: Start point (Cartesian)
Line segment in front/rear face contour G101-Geo
G101 defines a line segment in a contour on the front face/rear
face.
Parameter:
X: Final point (polar; diameter value)
C: End angle (polar)
XK: Final point (Cartesian)
YK: Final point (Cartesian)
AN: Angle to positive XK axis
Q: Intersect. pt. or Final point if the line segment intersects a
circular arc (default: 0)
0: Near point of intersection
1: Far point of intersection
BR: Chamf./round. – defines the transition to the next contour
element
When entering a Chamf./round., program the theoretical end
point.
No entry: Tangential transition
BR = 0: No tangential transition
BR > 0: Rounding radius
BR < 0: Width of chamfer
AR: Incr.angle to foregoer ARi (AR corresponds to AN)
R: Line length
Programming:
XK, YK: Absolute, incremental, modal or ?
X, C: Absolute, incremental or modal
ARi: Angle to the previous element
ANi: Angle to the subsequent element
