Computer Aided Design and Manufacturing Evaluation of Milling Cutter when High Speed Machining of Hardened Steels

This paper presents the influence of CAD modelling and CAM simulation advanced techniques for hard milling technology. The main aim of simulations is the ability and importance to improve and optimize hard milling process even before the real production of its own products, because their manufacturing process is rather expensive. The reached results present us roughing and finishing process of hard milling and milling strategy or generation of tool-paths in CATIA V5. All simulations of milling experiments show that the proposed clear-up tool path works well in the real cutting process and can improve the machining efficiency of the machining process. At the same time, the manufacturing must have the advanced process equipment and method due to the requirements of the design performance and machining efficiency. Finally, hard milling simulations in CAD/CAM system CATIA V5 were performed in order to determine and evaluation of suitability of the proposed shapes of the hard milling product.
