Remaining volume after smoothing(RVAS) variation according to runout

Mold-manufacturing process consists of machining and finishing process that are strongly related in each other. But there are few studies about mold-manufacturing process to control those two processes simultaneously. Especially, runout distorts the machined surface from expected so it changes the finishing process and mold-manufacturing time. In this work, basic analyses and experiments were carried out to study RVAS variation according to runout in HSM. To perform those analyses, firstly surface generation analysis was done including runout in ball end milling and then the RVAS that could relate machining and finishing process was proposed. And the optimal finishing process in HSM according to RVAS was also proposed. Through experiment runout occurrence and above analyses were verified.
