Abstract In order to improve the turning process performance of ultra-high strength steel in aircraft landing gear, the effects of different cutting parameters on cutting force and surface roughness of A100 steel and 300M steel were studied by orthogonal test. Multivariate linear regression analysis of cutting parameters was carried out, and empirical formulas of three-dimensional cutting force and surface roughness were established. The results show that when cutting A100 steel, feed has the greatest impact on cutting force. When turning 300M steel, back cutting depth has the greatest impact on cutting force. For surface roughness, back cutting depth has the greatest impact on the two materials, and spindle speed has the smallest.

车削参数对超高强钢车削性能的影响

摘要 为提高飞机起落架超高强度钢车削加工性能，采用正交试验研究了不同切削参数对A100钢和300M钢切削力和表面粗糙度的影响。对切​​削参数进行多元线性回归分析，建立三维切削力和表面粗糙度的经验公式。结果表明，切削A100钢时，进给量对切削力的影响最大。车削300M钢时，后切深度对切削力的影响最大。对于表面粗糙度，后切深度对两种材料的影响最大，主轴转速最小。
