Abstract
A translation/rotation error compensation amount creating device creates, for a multi-axis machining apparatus having two rotation axes, a translation error compensation amount and a rotation error compensation amount both depending on the rotation axes. The translation/rotation error compensation amount creating device calculates the translation error compensation amount and the rotation error compensation amount based on an assembly error (set value) including at least an assembly error in a table surface or an assembly error in a spindle turning centerline in a multi-axis machining apparatus as well as the positions of the two rotation axes, and inputs the calculated error compensation amounts to a numerical controller controlling the multi-axis machining apparatus.
