Title:
MACHINE TOOL THERMAL DISPLACEMENT CORRECTION METHOD AND THERMAL DISPLACEMENT CORRECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/099599
Kind Code:
A1
Abstract:
Disclosed is a machine tool thermal displacement correction method comprising an inspection point information acquisition process (60) for acquiring thermal deformation positions in at least three inspection points which are set on a support body (10); an approximate curve calculating process (52) for calculating an approximate curve (C) of a deformed shape of the support body (10) on the basis of the thermal displacement positions at the inspection points; a correction value calculating process (53) for calculating a correction value (Rz) for a command position for a movable body (20) on the basis of said command position and the approximate curve (C); and a correction process (56) for correcting the command position for the movable body (20) by means of the correction value (Rz).
