Improving the Efficiency of Metalworking by the Cutting Tool Rake Surface Texturing and Using the Wear Predictive Evaluation Method on the Case of Turning an Iron–Nickel Alloy

The article proposes and substantiates the function of predictive evaluation using criterion relative efficiency a cutting tool with microtextured rake surface based on tangential force temperature. Comprehensive durability tests carried out under various processing modes measurement heat power parameters made it possible to create an experimental base for mathematical modeling. An empirical model modified multiplicative functions non-constant indicators in form linear dependencies factors was used planning experiment heat-resistant alloy wear assessment order determine rational modes. Predicting use work obtain 1.3-fold increase durability.
