Abstract
A numerical controller for controlling a multi-axis machine tool for machining with three linear axes and three rotating axes has a function for compensating a setting error that arises when a workpiece is set. This numerical controller determines compensated linear axis positions of the three linear axes and compensated rotating axis positions of the three rotating axes by calculating compensated tool position and direction depending on the setting error such that the tool position and direction on the workpiece setting coordinate system are maintained on the workpiece having such a setting error, and drives and controls the axes according to the compensated linear axis positions and compensated rotating axis positions.
