摘要
分析了Lee—Shaffer刚塑性滑移线场切削模型的不足 ,强调切屑形成过程中存在加工硬化 ,据此建立了基于线性强化弹塑性材料的切屑卷曲模型 ,定义了衡量切屑卷曲程度的参数———刀—屑接触长度比λ,并通过切削试验对新的切屑卷曲模型进行了验证。
By analyzing the defect of the Lee-Shaffer cutting model and emphasizing the existence of work harden process in the chip formation, an improved metal cutting model based on the linear reinforced elastic and plastic material is established. The parameter λ is defined as chip-tool contact ratio by which the lever of the chip curl can be determined. The results of theoretic analysis based on this new model are supported by the experiments.
