 Type KC: Orthogonal Cross Hole - Inner Diameter (Cross Hole＞ Main Bore) XZC Machine Axis

Polar interpolation enables 3-axis simultaneous control of XZC axes for milling the contours of the workpiece.
Turn on the polar interpolation with G12.1 or G112 (MELDAS G codes) after the tool rotation is turned on.
While polar interpolation is turned on, the XZ motions of the tool is synchronized with the spindle (C-axis) rotation.
