294 6 DIN Programming
6.5 Simple Linear and Circular Movements
Parameters G2, G3
X end point (diameter value)
Z end point
R radius
I center point incremental—(distance from starting point to center
point; diameter value)
K center point incremental—(distance from starting point to center
point)
Q point of intersection (default: Q=0): Specifies the end point if
two solutions are possible (see graphic support window).
B chamfer/rounding: At the end of the circular arc you can program
a chamfer/rounding or a tangential transition to the next contour
element.
No entry: Tangential transition
B=0: No tangential transition
B>0: Radius of rounding
B<0: Width of chamfer
E special feed rate for chamfer/rounding—default: Active feed
rate

END
If you do not program the center, MANUALplus
automatically calculates the possible solutions for the
center and chooses that point as the center which
results in the shortest arc.
The direction of rotation of G2/G3 is shown in the
graphic support window.
