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. In this technology, a small diameter ball end mill is used at the cutting conditions such as small depth of cut, high rotational speed and high feed speed. And, it becomes important to optimize the specifications of the tool for high-speed milling. This paper describes the effects of surface treatment for ball end mill tool. The cutting edges and flank/rake faces of tool could be treated by magnetic assisted polishing method and micro blasting method. And, the cutting characteristics of high-speed milling were investigated.
