摘要
微细铣削具有加工零件型面复杂、生产效率高、成本低、材料种类多等优点,成为一种重要的微纳制造使能技术,广泛用于生物医疗、航空航天、能源动力和电子通信等领域。铣削过程中,切削热、切削温度将影响加工质量、刀具耐用度。文中使用有限元法建立微铣削热-力模型,研究微细铣削过程中切削热和温度场的分布,对降低刀具磨损、提高表面加工质量具有重要的意义。
Micro milling technology is a new manufacturing technology which can process small size and complex structure parts. Micro milling technology has the advantages of high machining efficiency, low machining cost, variety of processing materials and flexible processing. At present, micro milling technology has been an important micro/nano enabling manufacturing technology for machining micro parts. Micro milling technology is widely used in fields of biomedicine,aerospace, energy power, and electronic communications. The cutting heat and temperature distribution may affect dramatically cutting performance and tool wear in the process of micro milling. This paper uses finite element method to establish the thermal-force model of micro milling and study the cutting heat and the distribution of temperature field. It is of great significance to reduce tool wear and improve the quality of surface processing.
