摘要
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.
