helical motion can assign 2 other arc interpolation axes with synchronous

motion, which method is just to add a moving axis that isn’t arc

interpolation.

Threading

Polar coordinates instruction: polar coordinate (radius and angle), the

positive direction of angle is the CCW direction of positive direction of the

first axis in the selected plane, and the negative direction is CW.
