ABSTRACT:
A numerically controlled machine tool machines a workpiece into a roll while rotating the workpiece at a prescribed speed, moving the tool back and forth radially thereof, and moving the tool axially thereof. The misalignment of the workpiece with the axis of the machine tool can be corrected by measuring the amount of misalignment of the axis of the workpiece and entering the measured amount as corrective data into a control system which stores numerical control data produced by successively programming amounts of radial movement of a tool dependent on axial positions of the tool; calculating corrected values of, among said numerical control data, the positional data of the tool in the axial direction and/or corrected values of the data on the amounts of movement of the tool in the radial direction, based on the corrective data; and controlling said tool based on the calculated corrected values to machine the workpiece.
