3.4 CIRCULAR INTERPOLATION (G02,G03)
Circular interpolation of optional angle from 0 deg to 360 deg can be
specified.
G02: Clockwise (CW) circular interpolation
G03: Counterclockwise (CCW) circular interpolation
Fig.3.4 (a) Direction of the circular interpolation
Feed rate of the tangential direction takes the speed specified by the F
code.
Planes to perform circular interpolation is specified by G17, G18, G19.
Circular interpolation can be performed not only on the X, Y, and Z
axis but also on the parallel axes of the X, Y, and Z axes.
G17: Xp-Yp plane
G18: Zp-Xp plane
G19: Yp-Zp plane
where
Xp: X axis or its parallel axis
Yp: Y axis or its parallel axis
Zp: Z axis or its parallel axis
Parameter is set to decide which parallel axis of the X, Y, Z axes to be
the additional axis.
