In this research, the so-called Intelligent CAM System for Die and Mold Making (ICAMS) was developed. The objective of the system is to enable inexperienced operators to successfully apply the method of direct endmilling of hardened steel by using (Al, Ti)N-coated micro-grain carbide cutters for the manufacturing of dies and molds. Therefore, the developed system supports the functions of process planning for rough and intermediate-rough cutting, decision of cutting conditions, tool life prediction and cutting force prediction. Furthermore, a new technique of NC programming, the so-called constant cutting force programming method has been developed. The cutting forces are kept constant during the endmilling of arbitrary shaped contours by adjusting the cutting feed accordingly. The intelligent CAM system has been experimentally tested for rough and intermediate-rough machining. Fairly good results regarding productivity and costs have been achieved by using this system.
