Abstract:Sculpture surface machining is a critical process commonly used in die/mold industries. Since there is a lack of scientific tools in practical process planning stages, feedrates for CNC machining are set individual constant values all along the toolpath. In this paper, an enhanced mathematical cutting force model is presented and is used for selecting varying and 'appropriate' feed values along the tool path in order to decrease the cycle time in sculpture surface machining. The model is tested under various machining conditions and proved to be effective.
