提出了一种新的脆性材料单点金刚石车削加工模型。 使用中断切削方法的实验允许确定模型参数，该模型参数提供用于确定材料相对于前角、刀尖半径和加工环境的可加工性的定量方法。 该模型使用两个参数，临界切削深度和亚表面损伤深度，来表征延性制度的材料去除过程。 模型中还包括一个参数，用于设置定义为最大进料速率的工艺极限。 加工实验验证了模型，并允许确定最佳加工条件。
A new machining model has been developed for single point diamond turning of brittle materials. Experiments using the interrupted cutting method allow model parameters to be determined that provide a quantitative method for determining the machinability of a material with respect to the rake angle, tool nose radius and machining environment. The model uses two parameters, the critical depth of cut and the subsurface damage depth, to characterize the ductile-regime material removal process. Also included in the model is a parameter used to set a process limit defined as the maximum feed rate. Machining experiments have verified the model, and allow for determination of optimum machining conditions.
