4.6 Circular interpolation with center point and end point (G2/G3, I=, J=,
K=AC...)
Function
Circular interpolation enables machining of full circles or arcs.
The circular movement is described by:
• The end point in Cartesian coordinates X, Y, Z and
• the circle center point at addresses I, J, K.
If the circle is programmed with a center point but no end point, the result is a full circle.
