Abstract

The purpose of this study is to investigate the relationship between the surface roughness and cutting force for the die shape and factor change using CAD/CAE/CAM. RPM, feed rate, and step over were chosen as the main factor for cutting force. To estimate the correlation between cutting force and surface roughness, cutting force was predicted using the DOE(design of experiments) and DEFORM^TM-3D(software of finite element analysis), surface roughness was measured through experiments. The optimal level for each factor was considered, and the most effective factor was evaluated using the Taguchi method(one of DOE). In this study, the machining conditions to obtain a particular surface roughness based on the measured value were derived.
