Title:
CONTROL METHOD OF MACHINE TOOL, AND CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2015191306
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control method of a machine tool capable of calculating a translation axis command value or a rotation axis command value correspondingly to any arbitrary axial configuration, and a control device.SOLUTION: In the machine tool, a main axis on which a tool is mounted, and a table holding a workpiece are relatively moved by two or more translation shafts and one or more rotation axis and the workpiece is processed by the tool. A plurality of at least either main shafts or tables are provided and the control method of the machine tool includes calculating a translation axis command value and a rotation axis command value by correcting a positional error of the tool caused by an error of the machine tool and relative to the workpiece. The control method of the machine tool includes: a selection step of selecting any arbitrary axis configuration; a translation axis correction value calculation step S40 of calculating a correction value of the translation axis for correcting the positional error in a command value coordinate system of the translation axis included in the arbitrary axis configuration; and a rotation axis correction value calculation step S50 of calculating a correction value of the rotation axis for correcting the positional error in a command value coordinate system of the rotation axis included in the arbitrary axis configuration.
