Document Type and Number:
WIPO Patent Application WO/2016/051542
Kind Code:
A1
Abstract:
A numerically controlled machine tool (10) in which a numerical control program acquired from a reading and interpreting unit (52) of a numerical control device is executed by a distribution interpolating unit (54) and servo control units (56), (58) and (60) to drive a feed shaft configured from a coarse movement mechanism and a fine movement mechanism, causing a tool to move relative to a workpiece, and thereby machining the workpiece, wherein the difference between a movement command for the feed shaft, and an output value which varies on the basis of said movement command is obtained, a movement command for the coarse movement mechanism is generated on the basis of said movement command, and a movement command for the fine movement mechanism is generated on the basis of said difference.
