Abstract

On-axis single point diamond turning experiments were performed on (111)CaF₂ to investigate the effect of the resulting force system on the single crystal response. The cutting and thrust forces were measured and the resulting surface topography was characterized. The Schmid factors and fracture factors were calculated, and their ratio

{(\frac{S_{f}}{F_{f}})}^{*}

was determined as a function of cutting direction and resultant force angle. It was found that this approach can be used to predict the number and location of resulting fracture lobes on the surface with respect to the lattice orientation. Two regimes with different topography were predicted when turning (111)CaF₂, depending on the resultant force angle.

单点金刚石车削 (111)CaF2 时结果力方向的影响

对 (111)CaF2 进行了轴向单点金刚石车削实验，以研究由此产生的力系对单晶响应的影响。测量了切削力和推力，并对由此产生的表面形貌进行了表征。计算了 Schmid 因子和断裂因子，并确定了它们的比率 SfFf* 与切削方向和结果力角度的函数关系。研究发现，这种方法可用于预测与晶格取向有关的表面断裂裂片的数量和位置。在车削 (111)CaF2 时，根据结果力角度的不同，预测出两种具有不同形貌的状态。
