The purpose of this study is the development of a lathe which can cut any pistons of oval shape with high speed, accuracy and precision by CNC (Computer Numerical Control) method. Y axis which is the position determining mechanism with high speed response was added to the CNC lathe and the ovality and profile was cut under the control of C-Y-Z axes at same time. In the case of ovality of φ0.2mm, the productivity can be improved up to 2500rpm(Y axis : 83Hz) by high speed cutting than modeling method. Since a personal computer is used, it is easy to change the shape of piston and can be applied promptly to many types of piston shape by only changing data files.
