在切削淬硬模具钢SKD11中,为开发和选用与生产条件相匹配的具备优化几何角度的高性能铣刀,对专用于高硬度模具钢SKD11铣刀的几何角度进行了优化及试验分析。设计了4类不同几何结构的TiAlN复合涂层铣刀。从切削力、切削振动、切削变形、铣刀耐用度以及铣刀磨损机理等方面对这4类铣刀高速铣削SKD11过程进行了研究,综合评价其铣削性能,确定了在常用的高速加工生产条件下的优化铣刀。所选择的优化槽形铣刀具的寿命比之其他刀具延长3倍,在切削力和切削振动方面,该刀具具有最稳定的表现,而且大小较其他刀具下降70%。
In cutting hardened tool steel SKD11, to optimize the geometric angle of the SKD11 cutter designed for high-hardness tool steel and to develop and select a high-performance milling cutter with optimized geometries that match the production conditions, the optimization and test analysis are carried out. Four types of TiAlN composite coating cutters with different geometries were designed. From the aspects of cutting force, cutting vibration, cutting deformation, durability of milling cutter and wear mechanism of milling cutter, this paper studied the high speed milling SKD11 process of four types of milling cutter, evaluated the milling performance synthetically and determined the common manufacturing conditions of high speed machining Under the optimized milling cutter. The selected grooved milling tool has a life extension of 3 times longer than that of other tools. The tool has the most stable performance in terms of cutting forces and cutting vibrations, and its size is reduced by 70% compared with other tools.
