・Others
When the tool movement changes linear to circular (helical), circular (helical) to
linear, or circular (helical) to circular (helical), the start, end, and center points of a
circular (helical) movement are projected on the compensation plane that is
perpendicular to the tool axis, and a compensation vector is calculated in the plane.
The obtained vector is added to the originally specified position to create a position
to be specified. Then, the tool is moved linearly or circularly (helically) to the
created position.
