High Speed Machining of Difficult-to-cut Material using Ball Endmill
볼 엔드밀을 이용한 난삭재의 고속가공 특성
Abstract
Inconel 718 is one of the most difficut workpiece for machining, So it is necessary to evaluate the machining characteristics of Inconel 718 In this study, High speed machining of this material was carried out with Tin coated WC ball endmill and TiN coated HSS ball endmill. The cutting force and shape of machined surface and cip type were investigated according to variation of cutting speed,feed rate and depth of cut
