Abstract
The actual axial center position of a helical gear relative to the axial center position of a rotary table is calculated on the basis of input gear dimensions and information from a touch probe. Correction values for the positions and motions of the rotary table and a grindstone are calculated on the basis of the actual axial center position of the helical gear.Operation values for the rotary table, a column, a saddle, and a grindstone head are calculated by adding the correction values to reference values for the positions and motions of the rotary table and the grindstone. Motors are controlled in such a way that operation is carried out at the operation values to thereby carry out form grinding.
