中文摘要：
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%。
英文摘要：
To select high performance milling tools with optimum geometry structure suitable for machining hardened steel SKD11, geometry structures of tools are optimized. Four kinds of TiAlN coated cemented carbide tools are developed. The milling performance in high-speed milling hardened steel SKD11 by using these four kinds of tools is evaluated through the aspects of cutting force, cutting vibration, chip deformation, tool life, and tool wear mechanism, thus determining the optimum milling tool. The tool life of the optimum tool is 3 times of that of other tool, and the cutting force and vibration decrease by 70% compared with that of other tools. It has the most stable cutting performance.
