Circular Arc On Front/Rear Face G102/G - HEIDENHAIN MANUALPLUS 620 User Manual

Circular arc on front/rear face G102/G103

G102/G103 moves the tool in a circular arc at the feed rate to the "end
point." The direction of rotation is shown in the graphic support
window.
Parameters
X Final point (diameter)
C Final angle—for angle direction, see help graphic
XK Final point (Cartesian)
YK Final point (Cartesian)
R Radius
I Center point (Cartesian)
J Center point (Cartesian)
K Center point for H=2, 3 (Z direction)
Z Final point (default: current Z position)
H Circular plane (working plane)—(default: 0)
H=0, 1: Machining in XY plane (front face)
H=2: Machining in YZ plane
H=3: Machining in XZ plane
Parameters for contour description (G80)
AN Angle to positive XK axis
BR Chamfer/rounding. Defines the transition to the next contour
element. When entering a chamfer/rounding, program the
theoretical end point.
No entry: Tangential transition
BR=0: No tangential transition
BR>0: Rounding radius
BR<0: Width of chamfer
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
Using the parameters AN, BR and Q is only allowed if the
contour description is concluded by G80 and used for a
cycle.
