Abstract—

The present study analyzed the effect of protective coatings of replaceable hard-alloy plates on cutting forces when milling austenitic high-manganese Hadfield (110G13L) steel. S30T, 1130, S40T, and 4240 hard alloys with PVD and CVD coatings were explored. The analysis was conducted on a milling machining center with a dynamometer plate installed on the table. The experiment was based on the orthogonal planning matrix. The Taguchi method was employed to identify a coating with the best properties. The analysis of variance showed that the tool feed has the greatest effect on active cutting forces. The specific feed gravity was 65.22%. The regression analysis revealed that to minimize and predict cutting forces for the entire range of cutting conditions, S30T alloy with a protective TiAlN PVD coating is preferable in machining austenitic 110G13L stainless steel. The results can improve the machining efficiency for Hadfield steel products produced by machine-building enterprises.

哈德菲尔德钢铣削过程中刀片保护涂层对切削力的影响

摘要——

本研究分析了铣削奥氏体高锰哈德菲尔德 (110G13L) 钢时可更换硬质合金板的保护涂层对切削力的影响。探索了具有 PVD ​​和 CVD 涂层的 S30T、1130、S40T 和 4240 硬质合金。分析是在工作台上安装测功盘的铣削加工中心上进行的。该实验基于正交规划矩阵。采用田口方法来确定具有最佳性能的涂层。方差分析表明刀具进给对主动切削力的影响最大。饲料比重为65.22%。回归分析表明，为了最小化和预测整个切削条件范围内的切削力，具有 TiAlN PVD ​​保护涂层的 S30T 合金更适合加工奥氏体 110G13L 不锈钢。研究结果可提高机械制造企业生产的哈德菲尔德钢产品的加工效率。
