Abstract: In a displacement compensation control method and module for an object mounted movably on a driving rod unit and movable between first and second positions relative to the driving rod unit during processing, a detecting unit determines a displacement amount of a free end of the driving rod unit from a reference position in an axial direction of the driving rod unit as a result of thermal deformation of the driving rod unit during high-speed rotation.

A distance between the first position and the first compensation position, and a distance between the second position and the second compensation position are equal to the displacement amount.
