Circular Interpolation - Siemens SINUMERIK 808D User Manual

See the illustration for linear interpolation in three axes using the example of a slot:
Programming example
N05 G0 G90 X40 Y48 Z2 S500 M3
N10 G1 Z-12 F100
N15 X20 Y18 Z-10

Circular interpolation

11.4.1 Circular interpolation: G2, G3
Fu n ctionality
The tool moves from the starting point to the end point along a circular path. The direction is determined by the G function:
