Programming example: Polar coordinates 
 
; Starting point circle for N10 
 
Circular interpolation via intermediate point: CIP 
Functionality 
If you know 
 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, ...). 
The configured dimensional data G90 or G91 applies to the end point 
the intermediate point.
