英文摘要：

An effective method was presented to simulate the physical characteristics of complex parts in the cutting process. A 2-D cutting model was built by abstracting the complex cutting process. The special cutting simulation software was used to calculate the cutting force and temperature, and the common finite element software was used to simulate the physical conditions of 3- D parts and tools in the affect of cutting force and cutting heat. So the physical simulation of cutting process of complex parts can be realized. Taking a hard disk drive part as an example, the implement process of simulation was introduced. The simulation results are meaningful to the cutting process optimization.
