Radial toolpaths are created from the center of the part toward the boundary. This figure shows a radial toolpath example.
The center of the pattern is automatically calculated unless the Center point milling attribute is set. Not all feature shapes lend themselves to this manufacturing style. Features long in one direction and skinny in the other probably aren’t best milled in this way. The radial term is only a rough description of the actual path as not all feature shapes lend themselves to a truly radial pattern.
