<p><P>PROBLEM TO BE SOLVED: To provide a method and the like in a machine tool, capable of correcting a position error of a tool tip point due to a geometrical error as well as correcting an attitude error of the tool and capable of operating a correction value of a rotation axis independent of a rotation axis instruction value with a small calculation amount. <P>SOLUTION: A correction value operation method of a machine tool, for correcting a position error and an attitude error of a tool with respect to a workpiece due to a geometric error in a machine tool having two or more translation axes and one or more rotation axes, includes: a rotation axis correction value operation step (S3) for operating a correction value of the rotation axes by using a geometric parameter representing the geometric error; and a translation axis correction value operation step (S4) for operating a correction value of the translation axes by using a command value of each of the rotation axes and a command value of each of the translation axes, and the geometric parameter. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
