Title:
MACHINE TOOL AND METHOD OF CORRECTING DISPLACEMENT OF MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2006/109445
Kind Code:
A1
Abstract:
A machine tool and a method of correcting the displacement of the machine tool. The machine tool comprises temperature sensors (28 to 36) installed on a machine tool body (11, 41) at a plurality of positions, a displacement amount detection means (25) detecting the thermal deformation amounts of components (12 to 15) based on measurements by the temperature sensors (28 to 36) and in consideration of the warpages thereof caused due to the temperature changes of their surfaces with large temperature changes and their surfaces positioned on the opposite side thereof, a conversion means (25) converting the thermal displacement amounts of the components (12 to 15) detected by the displacement amount detection means (25) to their axial displacement amounts at working points (P), and a correction means (25) correcting the relative movement amounts on the axes of the components according to the conversion by the conversion means (25).
