　　报告内容简介 

　　Tile: Key improvements in precision machining of difficult-to-cut materials 

　　Abstract: Requirements for high-dimensional precision and optical quality surfaces as well as a decrease in costs and cycle time in die and mold manufacturing are rapidly increasing. Die and mold manufacturing represents a significant link in the entire production chain. The production of nearly all mass produced discrete parts utilizes dies and molds. Therefore, the quality of the dies and molds directly affects the quality of the produced parts. In this talk, the latest machining technologies and details that related to the promising machining methods, such as thermal-chemical based diamond machining, ultrasonic vibration-assisted machining, and high speed mirror surface machining of difficult-to-cut materials, e.g., hardened steel and hard and brittle materials and advanced ceramics, will be discussed. 

　　模具制造是大规模生产的重要工艺链环节。因此，模具的加工质量直接影响到所生产零件的制造水平。近年来，模具行业对面形精度和光学质量表面的要求与日俱增，同时要求降低模具制造成本和缩短模具制造周期。在这次报告中，王博士将介绍日本模具加工行业最新的加工技术和工艺细节，重点讨论未来最有前景的加工方法，如基于热化学效应的金刚石加工、超声振动辅助加工、先进陶瓷等硬脆材料的高速镜面加工。
