Numerical simulation of turning contact temperatures with varying material yield strength and tool wear

The results of numerical simulation the main component of cutting forces and temperatures at the contact zones of the face of the cutter with chip and flank with the workpiece depending on the tool wear and physico-mechanical properties of the workpiece material. The values of fluctuations in the cutting force and contact temperatures are determined depending on the variation of the stress yield of the workpiece material during machining of the workpieces material when processing workpieces made of steel 45 and steel 12KH18N10T are established. The degree of influence of tool wear on the flank on cutting forces and contact temperatures is determined.
