Abstract: Ultraprecision machine tools can be expert power together with a CAD/CAM system in generating tool paths. However, CAM systems generally focus on generating NC data. Consequently, operators have to perform process planning by considering the features of machine tools, cutting tools and workpieces. Above all, the setting error may cause interference between the cutting tool and the workpiece, and result in low machining accuracy. Therefore, this study deals with the development of a CAPP/CAM system in ultra-precision micromachining to assist operators in relation to settings. The developed system determines the number of the used control axes of the machine tool, and calculates the required setting accuracy, while preventing tool interference and maintaining the shape error within the tolerance. From the simulation result, it is found that the CAPP/CAM system is effective in producing micro parts easily and accurately.
