A Study on the Machinability Progress by the Structure Improvement of Materials for Automobile's Piston

In this paper the following conclusions were obtained after examining and analyzing data through the various experiments by adopting automobile's piston as the experimental materials among the automobile materials which are being commercialized. The various experiments have been carried out with the object of presenting the selection of rational. economic materials and criterion according to the improvement of machining characteristics by grasping the strength and weakness of existing various materials and using the effects of metallic structure variables as well as satisfying the required conditions.
