Abstract

High-speed machining (HSM) [7], over the past few years, has gained great importance and visibility, as current technological advances have supported its implementation. Due to various improvements in cutting tool and machine technology, HSM [8] has become an economical manufacturing process for production of various parts with increased high precision and surface quality. Until lately, high-speed manufacturing was applied in machining of the aluminum alloys for production of only complicated parts, which are utilized in the aircraft industry. This was the technology that was effectively applied with substantial improvements in machine tools, controllers, and spindles. Recently, with the development of cutting tool technologies, HSM [10] has also been engaged in machining alloy steels for making dies/molds used in the production of a wide range of automotive components, as well as plastic molding parts. HSM is defined as machining at significantly high cutting speeds and feed rates compared with those in old-fashioned methods. HSM [17] is achieved in high material removal rates, lower cutting forces, improved part precision, and reduced lead times. The dissimilarity between conventional machining and HSM is based on the workpiece material being machined, type of cutting operation, and the cutting tool used. High-speed dynamic milling toolpaths utilize the entire flute length of their cutting tools to achieve great efficiency in milling. They are designed to maximize material removal [18,19] while minimizing tool wear. Additional benefits gained by using high-speed dynamic milling toolpaths include (i) tool burial avoidance, (ii) minimum heat buildup, and (iii) better chip evacuation. Following are high-speed dynamic milling toolpaths available in Mastercam [6].
