2.9.6.5 Circular interpolation with polar coordinates (G2/G3, AP, RP)
Circular interpolation version, that uses the circle end point in polar coordinates for the
interpolation.
The following rule applies:
● The pole lies at the circle center.
● The polar radius corresponds to the circle radius.
Syntax
G2/G3 absolute pressure=... Recipe procedure=...
Meaning
G2: Circular interpolation clockwise
Effective: Modal
G3: Circular interpolation counter-clockwise
Effective: Modal
