Figure 10-16 Possibilities of circle programming with G2/G3 using the example of the axes X/Y and
G2
G2/G3 remains active until canceled by another instruction from this G group (G0, G1, ...).
The path velocity is determined by the programmed F word.
Programming
G2/G3 X... Y... I... J... ; Center and end point
G2/G3 CR=... X... Y... ; Circle radius and end point
G2/G3 AR=... I... J... ; Opening angle and center point
G2/G3 AR=... X... Y... ; Opening angle and end point
G2/G3 AP=... RP=... ; Polar coordinates, circle around the pole
Note
Further possibilities for circle programming result from:
CT - circle with tangential connection and
CIP - circle via intermediate point (see next sections).
