피스톤 가공용 CNC 선반 HOT-1000 개발에 관한 연구

A study on the Development of CNC Lathe HOT-1000

The purpose of this study si the development of a lathe which can cut any pistons of oval shape with high seed, accuracy and precision by CNC (Computer Numerical Control) method. Yaxis which is the position determinating 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 tile. In the case of ovality of $\Phi$ 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.
