WORKPIECE SUPPORTING METHOD FOR ENABLING COORDINATE DISLOCATING DRIVE OF REFERENCE POINT FOR DRIVING OF WORK SURFACE OF WORK PIECE BY EACH ANGULAR DISLOCATION ON MULTIPLE SHAFT CENTER OVERLAP SURFACE

摘要

PURPOSE: To provide a workpiece supporting method capable of changing a reference point for driving a work surface of the workpiece. ;CONSTITUTION: The dislocation driving is independently executed by a first turntable 101 and a second turntable 102 forming at least double overlaps to the different shaft centers, a reference point of a work surface of the uppermost workpiece is normally dislocated to an arbitrary absolute position, or rotated and driven about one of the shaft centers. The workpiece can be linearly dislocated between both shaft centers S1, S2.;COPYRIGHT: (C)1995,JPO
