Circular arc in front/rear face contour G102/
G103-Geo

G102/G103 defines a circular arc in a front or rear face contour.

Direction of rotation (see help graphic):

G102: In clockwise direction

G102: In counterclockwise direction

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
R

Radius

I

Center in Cartesian coordinates

J

Center in Cartesian coordinates

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 circular arc intersects a line

segment or another circular arc (default: 0):

0: Near point of intersection

1: Far point of intersection

Programming

X, XK, YX:

Absolute, incremental, modal or "?"

C:

Absolute, incremental or modal

I, J:

Absolute or incremental

End point must not be the starting point (no full circle).
