Abstract


Stainless steel material due to its excellent mechanical properties and chemical properties of broad use in the aerospace, marine , nuclear equipment . Due to the intractability of the stainless steel , making the cutting efficiency of its processes and parts machined surface quality , tool wear serious . These issues have become obstacles restricting the development of stainless steel processing , successfully overcome these problems and will also increase the level of processing of other difficult to machine materials provide a reference , of great significance to the development of China 's equipment manufacturing industry papers of different cutting parameters at right angles to the cutting end milling process of cutting force , cutting temperature and chip . Through the study of the constitutive equation of AISI-316L Material Johnson-cook contact model of the tool - chip , chip separation model , chip damage and fracture the key technology to build a finite element model of orthogonal cutting . Chip separation model is the most important part of the whole process of cutting simulation , also have an important role in the formation mechanism of the chip , the paper unit the progressive damage lapse technology, the key technologies used in finite element simulation of the cutting process . Commercial finite element software ABAQUS cutting process simulation to study in the cutting process cutting speed , feed rate and other processing parameters stress , strain , temperature, etc. results . The analysis compared the causes and effects of the chip formation factors . Compared under the same conditions , the impact of different geometric model of the cutting force of simulation results . Opposition cutter geometry model was simplified 3D stand milling machining model discussed by comparison of simulation results and experimental cutting speed , feed rate machining parameters for milling force . Concludes the paper , the finite element model of the cutting process created by the papers inadequacies , and prospects for future development .
