摘要
在切进程产生的剩余压力在细工品性能上有重要影响。论文论述理论分析的一个方法以便详细解说和分析在切的剩余压力的形成机制。一个重要结论被得出积累的塑料紧张是决定性质和表面剩余的大小的主要因素，这在细工品强调。根据为剩余应力的分析模型，为剩余压力预言的一系列模拟在切 AISI 1045 钢期间被实现以便获得在表面剩余应力上把速度，切割的深度和工具边半径切成细工品的影响。并且这些影响在切从剩余应力的形成机制的观点被解释。结论让好适用性和罐头被用来在实际生产指导参数选择。
Residual stresses generated in cutting process have important influences on workpiece performance. The paper presents a method of theoretical analysis in order to explicate the formation mechanism of residual stresses in cutting. An important conclusion is drawn that the accumulated plastic strain is the main factor which determines the nature and the magnitude of surface residual stresses in the workpiece. On the basis of the analytical model for residual stress, a series of simulations for residual stress prediction during cutting AISI 1045 steel are implemented in order to obtain the influences of cutting speed, depth of cut and tool edge radius on surface residual stress in the workpiece. And these influences are explained from the perspective of formation mechanism of residual stress in cutting. The conclusions have good applicability and can be used to guide the parameters selection in actual production.
