Document Type and Number:
Japanese Patent JP2666512
Kind Code:
B2
Abstract:
A coordinate system correcting apparatus corrects a reference coordinate system set for a work space of a machine tool (3). A plurality of jig members (18) are distributedly arranged on a work table (12) of the machine tool (3), each of the jig members (18) has a plurality of right-angled parallelepipedic recesses (18a,b,c) and an intersection of three orthogonal planes of each of the recesses (18a,b,c) forms a space lattice point. The space lattice points defined by the jig members (18) coincide with predetermined normal space lattice points if the machine tool (3) is not distorted, and if the machine tool is distorted, deviate from the normal space lattice points. Eight adjacent space lattice points are located at vertexes of a hexahedron, respectively. When the machine tool (3) is distorted, the jig members (18) define distorted space lattice points, which are measured with a probe unit (17). According t to the normal space lattice points and distorted space lattice points, the reference coordinate system is three-dimensionally corrected for each of the hexahedrons.
