Comparative Study on Path Interval and Two Tool Condition Parameters in Ball and Filleted End Milling

Milling is widely used as a versatile, highly automated manufacturing process. The selection of tool and its machining conditions is an ever-present challenge inherent in the process. To provide some findings contributable for the process planning, this study focuses on ball and filleted end milling. After the path interval determinations were explained briefly, the characteristics of each procedure were revealed with experimental verifications. The results of computational procedures showed good agreement with the experimental ones. Then, predominant frictional distance and cutting speed were proposed for effective selection of machining conditions. The discussion was given based on the results obtained from the demonstrations. Moreover, the relationships to path interval were elucidated through the discussion. In conclusion, several outcomes were organized from the experimental and numerical evidences.
