在这项研究中，切削力的解析模型已经提出了铣削-磨削SiCp/Al复合材料。在该模型中，除切屑形成力和摩擦力分量外，还考虑了脱粘力和颗粒断裂力分量。应用颗粒断裂的能量理论和Griffith断裂理论，建立了SiCp/Al复合材料球磨过程中的脱粘力和颗粒断裂力分量。对所建立的切削力模型进行了验证性实验，结果表明，除个别实验值与理论模型值偏离较大外，所建立的切削力模型的平均预测误差小于8%，且在不同加工条件下与实验值具有较好的一致性。
In this study, an analytical cutting force model has been presented for mill-grinding SiCp/Al composites. In this model, except the chip formation force and frictional force components, debonding and particle fracture force components are considered in modeling the total force. The energy theory of particle fracture and Griffith theory of fracture were applied in developing the debonding and particle fracture force components during mill-grinding SiCp/Al composites. Results of verification experiments for the developed cutting force model reveal that the mean forecast error of this developed cutting force model is less than 8% excluding few experimental values which deviate far from the corresponding theoretical model values, and has acceptable agreement with the experimental values under different machining conditions.
