Abstract
Recently, high-speed milling technique for realizing high efficiency and high accuracy in the manufacturing of die and mold has become useful and important technology. And, it becomes important to optimize the specifications of the tool for high-speed milling. This paper deals with the cutting edge treatment of ball end mills for high-speed milling. Performed magnetic assisted polishing and micro blasting were done respectively as a pretreatment of TiAIN coating. As a result, the advancement of tool lives and surface roughness were proved with both of the pretreatments.
