Temperatures in orthogonal metal cutting
Web1 Jan 2024 · Fig. 4 shows the rake face temperature as a function of the uncut chip thickness and the cutting speed for AISI 1045. The temperature minimum of T RF = 398 °C is located at v c = 60 m/min and h = 0.1 mm. It can be stated that the main influence on the rake face temperature is caused by the cutting speed. As the cutting speed increases, … Web13 Apr 2024 · For example, Ke et al. proposed an orthogonal high-speed cutting model to study the relationship between the shear slip characteristics, the cutting zone and the cutting parameters of serrated chips. Furthermore, a theoretical model was constructed to directly calculate the shear angle using the chip geometric parameters without being …

The quantification of the heat flow distribution in the metal cutting process depending on the cut material and the process parameters is a research area with a long history. However, a quantification of the heat flow distribution between chip, tool, and workpiece is still a not fully solved problem and remains a necessary input value for the …
WebTemperature distributions for typical cases of orthogonal machining with a continuous chip were obtained numerically by solving the steady two-dimensional energy equation using the finite element method. The distribution of heat sources in both the primary and secondary zones was calculated from the strain-rate and flow stress distributions.
