The effect of temperature on strength in area of plastic contact on the front surface during cutting
The hypotheses about specific tangential forces on the anterior surface during cutting is considered. Based on available experimental and theoretical data on the influence of strain rate and temperature on the resistance to plastic deformation the effect of hardening and softening of the material in the plastic zone of contact of chips with the tool is obtained. The theoretical results are compared with experimental data. The proposed equations approximating dependence of shear strength on temperature during cutting. The results can be used to calculate forces and cutting temperatures.
