The machining of complex sculptured surfaces is an important technological topic in modern manufacturing, namely in the molds and dies sector. Today, this sector, with great importance to automotive, aircraft and others advanced industries, is placed in all industrialized or emerging countries. In the recent past, the traditional technology employed in molds and dies manufacture was a combination of con- ventional milling and electro-discharge machining (EDM) or electrochemical machining (ECM). Nowadays, high-speed milling (HSM) is used in roughing, semi-finishing and finishing of molds and dies with great success. This technology required modern CAM systems and process planning for 3 and 5-axis machining. HSM presents several advantages when compared with.
