Motors are becoming an environment-friendly alternative around the world. Environment-friendly automobile parts in particular require high quality and productivity. To improve these requirements, we studied a manufacturing technology called mold technology. A disadvantage of mold mass-production is a fatigue failure after a relatively large amount of friction and pressure on the processed products. Eventually, this leads to problems of repair costs, production stoppages, and quality defects. To address these problems, a surface- treatment technique is often used to improve mechanical properties by coating the mold surfaces. In this study, we measured the abrasion on (1) Tungsten Carbide punch and (2) TiAlCrN coated punch during the mold mass-production of the cold-rolled steel plate motor core made with SCP-1 (thickness of 1.0mm). With the extracted data, it is proved that using TiAlCrN coated punch affects the reduction of the inner diameter damage of the product. Furthermore, our goal is to reduce repair cost and improve productivity by predicting the lifespan of the mold and identifying the time expectancy of grinding, maintenance, and repair of the mold.
