Abstract

Ultraprecision machine tools can exert its performance together with CAD/CAM system. However, CAM systems generally focus on NC data generation. Consequently, operators have to make the process planning by considering the features of machine tools, cutting tools and workpieces. The process planning, which calculates suitable cutting conditions and generates tool paths, is more important when micro-parts are fabricated. Moreover, the setting error may cause the interference between the cutting tool and the workpiece and result in the low machining accuracy. Therefore, this study deals with the development of CAM system in ultraprecision micromachining to generate tool paths by considering high-aspect-ratio structures and to assist operators in setting operation. The effectiveness of the developed system is experimentally confirmed.
