基于UG的粗精铣合体刀具的设计

Design of Combined Tool for Rough and Fine Milling Based on UG

金属切削加工作为制造技术中最主要的工艺技术,决定着零件的加工效率、精度、质量和成本。基于已有的高速铣削机理及高速刀具技术研究成果,综合考虑高速切削的技术特点,开发设计了适合于铸铝材料高速切削的粗精铣合体铣刀,由粗精铣一次完成的工艺代替粗加工-精加工分步完成的加工工艺。通过单因素实验,得到不同刀片配比下表面质量的变化规律,得出在相同表面质量的要求下,精铣刀片数量越多,加工效率越高。另外,基于UG软件对粗精铣合体刀具进行三维建模,降低了刀具的研发成本,提高刀具的设计效率以及企业的市场竞争力。

Metal cutting which is the most important technology in manufacturing technology determines the machining efficiency,precision,quality and cost of parts in manufacturing industry.Based on the existing high speed milling mechanism and research results of high speed cutting tool technology,a coarse and fine milling combined milling cutter suitable for high speed cutting of cast aluminum materials was developed and designed.Coarse and fine milling in one process instead of rough machining-finishing process completed step by step.Through single factor experiment,variation rule of surface quality was got under different blade ratio. It is concluded that under the same surface quality requirements,the more the number of fine milling cutter pieces,the higher the machining efficiency. Based on UG software,three-dimensional modeling for coarse and fine milling combined cutting tools is conducted,and it reduces the research and development cost of cutting tools,improves the design efficiency of cutting tools and the competitiveness of enterprises.
