A device for the purpose of dressing of the regulating wheel for a tipless grinding machine.

摘要

PURPOSE:To correct a regulating wheel with high accuracy into the form of a revolution hyperboloid of one sheet by performing mutual interpolation in their coordinates with the coordinates of those points of the revolution hyperboloid of one sheet set as target values, on the basis of the data stored in an NC apparatus. CONSTITUTION:A regulating wheel 13 forms a revolution hyperboloid of one sheet, and the data necessary for executing the correction program for the regulating wheel 13 are stored in the memory of an NC apparatus. When the correction for the regulating wheel 13 is instructed, the throat circle diameter Dri of the revolution hyperboloid of one sheet which is to be corrected is calculated, and the diameter of the regulating wheel 13 at the position Wr in the axial direction is calculated, and the coordinate value of the initial point P0 to be interpolated is obtained, and the interpolated data having the working original point of a correcting tool 25 as starting point and the point P0 as end point is set into a pulse distributor in the apparatus, and the coordinates of a plurality of points P0, P1,... which are separated at a certain pitch (a) in the axial direction are obtained in succession, and at the same time, two shafts V and W are controlled, and the shape of the regulating wheel 13 is corrected.
