PCBN Cutting Tool Machining Performance And Geometry Parameters Optimization Research

With modern cutting technology continues to evolve, PCBN cutting tool industry more widely even have replaced many of the cutting tool industry to become the most commonly used tools, PCBN cutting tools in the process of development has gone through many stages, with PCBN cutting tools continuous development of the processing performance of automobile engine block had a profound impact, and from the many ways to speed up the development of the enterprise sector. With fierce competition in the automotive market, car manufacturers more and more attention to enhance production efficiency and product delivery time reduction, cost reduction so the auto companies imminent event, an important way to solve these problems is that high speed machining techniques.This paper focuses on experimental large-scale investment in foreign countries has been used PCBN (polycrystalline cubic boron helium) superhard cutting tool at different strain rates and different temperatures experiments PCBN tool fitted model and simulation experiments. By experimental design, complete PCBN cutting tools in the processing engine block cutting experiments, the experimental data are analyzed to obtain cutting force can be reduced parameter combination of various factors,, the establishment of milling force-empirical formula to achieve the theoretical prediction of milling force; PCBN tool wear life on experiments carried out to obtain the tool wear tho, grinding out the processing of automobile engine block better PCBN cutting tools.
