6.3.4 Temporary polar origin shift to the center of arc (G31)
When defining an arc in polar coordinates, the polar origin may be
shifted temporarily to the center of the arc.
G31 Temporary polar origin shift to the center of arc
Function G31 shifts temporarily the polar origin to the center of the
programmed arc. This function only acts in the block that contains it;
once the block has been executed, it restores the previous polar.
This function is added to the programmed circular interpolation G2/
G3. In this case, at least one of the center coordinates must be
programmed.
