Effect of Sticking Welding Layer on Temperature Distribution in the Rake Face of Cemented Carbide Tool AITranslate
Abstract AITranslate
Geometric and physical parameters were analyzed of sticking welding layer on the rake face of ce- mented carbide tool, and then theoretical heat transfer model and finite element model were established for tool rake face with or without sticking welding layer by using Laplace transform, inverse transform and the first law of thermodynamics, and combining the actual working conditions of cutting. The theoretical model solution and finite element model simulation were also carried out. The results show that the existence of sticking welding layer can affect temperature gradient of the tool substrate. The simulated temperature gradient change is verified by the theoretical model, resolving the problem that tool rake face temperature gradient change cannot be verified by experiments. Based on numerical simulation of the internal tempera- ture distribution of the tool with different sticking welding layer thickness and thermal coefficient, the in- fluence rules are obtained of sticking welding layer on temperature distribution in tool rake face. The error is less than 10% of cutting temperature of the tool with sticking welding layer from experiments and nu- merical simulation,verifying the accuracy of the finite element model.
