Abstract
PURPOSE: To automate centering in such a way that after a contactor which is concentrically installed in the center aq the tip of a main shaft has contacted the inner circumferential face of the reference hole of a work, it is moved in the directions of X axis and Y axis, and the center of the main shaft is made at one with the center of the reference hole on the basis of moving rate of the contactor.
CONSTITUTION: A contactor 6 is moved to the proper point Op near the inner circumferential face of the reference hole 2 of a work 1, and from the point Op the contactor 6 is moved by means of low speed feeding in parallel with X axis until it is brought into contact with the inner circumferential face of the reference hole 2. When the contactor 6 contacts the inner circumferential face of the reference hole 2, the low speed feeding is stopped, high speed feeding is done for the distance 2R of the main shaft in the negative direction of X axis by means of tape command, from which position the contactor 6 is moved by low speed feeding until it contacts the inner circumferential face, and the moving rate ε2 is measured. And the main shaft can be moved to the central position Ox of X axis by means of moving the main shaft for R+ε2/2 in the positive direction. Likewise is it done for Y axis. This facilitates to make the centers of the main shaft and of the reference hole 2 at one with each other.
