ABSTRACT:
A machine tool for processing a work piece into a non-circular cross-sectional configuration according to the invention precisely processes, for example, a piston cylinder into a non-circular cross-sectional configuration by inputting simplified data.
That is to say, a tool thereof is moved in a direction (X axis) perpendicular to an axis of the work piece by means of two servo motors. A first X axis servo motor operates to position the tool roughly in the X direction according to the size of the work piece. A second X axis servo motor finely vibrates the tool at high speed on the basis of program data. Since the displacement amount of the second X axis servo motor is fixed by working out the program data of a non-circular cross-sectional contour of the work piece through an automatic operation device, by inputting elements of the work piece in a simplified way and then storing the program data, the invention makes it possible to eliminate the inputting of the data to some extent and to process the work piece precisely and at high speed.
