Inventor: MAKIUCHI AKIRA
IPC: B23Q17/22
Filed: 2011-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a workpiece centering apparatus and a method capable of easily performing the highly accurate centering of a workpiece.SOLUTION: Positions of at least 3 equiangular points in the circumferential direction on a peripheral face of a workpiece set on a rotary table are measured by a position detection probe (S3). The amount of the deflection of the workpiece axis from the positions of the equiangular points and the phase position of the workpiece at which the deflection amount is maximum are calculated (S7). The phase position where the deflection amount of the workpiece is maximum is made to face a workpiece contact shoe of the centering apparatus by rotating the rotary table (S9). The position detection probe derives the relative position of the workpiece and a position detection block (S16). The position of the workpiece contact shoe is corrected (S17). The workpiece contact shoe pushes in the workpiece by the amount of deflection by moving the centering shaft member of the centering apparatus so that the centering of the workpiece is performed (S18).
