Circular Interpolation With Center Point And End Point (G2/G3, X - Siemens SINUMERIK 840D sl Programming Manual

Motion commands
9.6 Circular interpolation
9.6.2 Circular interpolation with center point and end point (G2/G3, X... Y... Z...,
I... J... K...)
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.
