Abstract

PURPOSE: To perform centering operation of a work simultaneously with operation of fitting the work to a machine in such a way that position of the work on a table is measured, arithmetic operation is done for the difference between measured results and machining reference positions, and a positioning device is controlled on the basis of the arithmetic operational results.
CONSTITUTION: A work is set by a shaft 14 equipped with saddle 11 and gears 15 which positions the work 2 in forward, backward, right and left directions by a screw shaft 10, and by a saddle 17 to position the work 2 in upward and downward directions. The set work is measured for its position by a measuring apparatus, and the measured results are compared with machining reference set values by an arithmetic operational unit. The work is positioned and held at the machining reference position by moving the saddle 11 or 17 through revolution of the screw shaft 10 or the shaft 14 by the difference in relation to the set values. This facilitates to perform centering operation of the work simultaneously with operation of fitting the work to the machine, and to perform reference face machining simultaneously with actual machining.
