Circular interpolation via intermediate point: CIP
Functionality
If you know three contour points of the circle, instead of center point or radius or aperture angle, then it is advantageous to
use the CIP function.
The direction of the circle results here from the position of the intermediate point (between starting and end points). The
intermediate point is written according to the following axis assignment:
I1=... for the X axis,
J1=... for the Y axis,
K1=... for the Z axis.
CIP remains active until canceled by another instruction from this G group (G0, G1, G2, ...).
Note
The configured dimensional data G90 or G91 applies to the end point and the intermediate point.
