As the automobile industry has recently developed, the automobile parts processing industry is also increasing. However, as the processing companies don't have their own studies or facilities now, their productivity is low. And they are in difficult situations because they cannot stay economically competitive. This study measured the cutting force, surface roughness, and tool wear of Ductile Cast Iron(FCD500) used in automobile brake modules in automobile parts to try to help harsh realities of automobile parts processing industry. And it drew the result by taking a test to increase productivity of processing companies as interrupted cutting is more used in industrial settings than continuous processing.
