A modeling method for turning parameters coupling based on minimum cutting tool wear

The relationship between cutting-tool wear and machining parameters has been a focus in the machinery manufacturing field. In this investigation, a modeling method for turning parameters coupling based on minimum cutting-tool wear was presented. The cutting-tool wear divided by surface area of the machined surface was taken as an evaluating level in the experiment. The association between cutting speeds and temperatures and, further, the association between the cutting parameters and temperatures were discussed. The optimal cutting temperature was hence revealed at which the wear of a cutting tool had the least value. The equation between temperature and cutting parameters was obtained with orthogonal experiments, and the cutting parameters coupling were hence determined at the minimum wear of the cutter. Besides, the mechanisms for the minimal wear of the cutter were analyzed in accordance with the characteristics of the cutting tool wear. The study would be beneficial for construction of a cutting database of metal materials.
