Cimatron high-speed cutting NC programming strategy and case studies
Abstract: In the modern manufacturing industry，High-speed digital processing technology has become parts of the main mean for a variety of precision application of CAD and CAM is one of the key technologies to high speed cutting(HSC)。In the paper，the function and advantages of High Speed Machining in Cimatron software are explained。The application of Cimatron in Mold manufacture is stated by a real instance，its path design and its processing simulation are analyzed, It also discusses the requirement of cutting-tools and how to select the cuttingparameters Some methods for high speed and high accuracy machining are described in HSM. Last to explain the programming method and character for coarse or accurate system to provide a reasonable choice of programming strategy To get the perfect path, make the optimization of production processes to the advantages of high-speed the basis of these researches，this paper put forward some problems that should be taken care of in the high-speed NC manufacture and summarised the key technology on NC automatic programming system for HSM is summed up at last.
Key words: Cimatron ;High speed machining; key technology;path design;NC programming
