PROBLEM TO BE SOLVED: To shorten the whole working time with the idle running time and machining time of a grinding wheel put together. SOLUTION: A sensor 17 for measuring the surface position of a workpiece 12, and the grinding wheel 13 are first brought into contact with a prescribed origin/datum such as a table 11 to acquire a sensor measured value S and a feed position value X simultaneously as an original point value pair S(0), X(0). When grinding of each workpiece 12 is completed, the sensor 17 and the grinding wheel 13 are brought into contact with the surface of the workpiece 12 to acquire the sensor measured value S and the feed position value X simultaneously as a machining completion point pair S(N), X(N). A correction quantityΔ(N) including the wear of the grinding wheel and the thermal deformation and elastic deformation of a machine is found from the original point value pair S(0), X(0) and the machining completion point pair S(N), X(N), and a machining pattern PP_std is shifted onto the table 11 side by the correction quantityΔ(N) portion.
