PURPOSE:To facilitate programing while to simplify correction of grindstone diameter by programing the cam grinding shape in perpendicular coordinates then converting the position in said coordinates for every micro-segment into polar coordinates system. CONSTITUTION:The cam shape is programed in perpendicular coordinates into NC tape 201 to read out NC data of one block from NC tape 201 through a tape reader 204 in accordance to control program in ROM203 in NC processor 202 during working. In case of path data of linear cutting, for example, current position of each shaft and increment are employed to operate the final point of each segment and stored in a data memory 205. Thereafter current position is converted into polar coordinates having center of rotation of cam as original point to operate pulse distribution on each shaft of polar coordinates on the basis of variation of polar coordinates values thus to control each servo motor 211, 212 and to control position of grindstone in cutting direction and rotation of work. |
