Milling Temperature

Based on the milling temperature experiments and researches, we established the milling temperature mathematical model using dimension analytic method,and the heat density function and superficial heat density function of the flat milling insert and the waved-edge milling insert, whose rake face is wave curve plane and created by the authors using the diathermanous theory. We describe the mathematic model of the instantaneous temperature field by the theory of the finite moving planar sources of heat. At last, a program was done to calculate the heat density function and the milling temperature field. According to the calculated results and plotted graph, it is proven that the highest temperature is not on the knifepoint and host edge, in fact, it is offset from the host edge a certain space. So we can make the conclusion that the waved-edge milling insert’s cutting capability is higher than the flat milling insert’s which is consistent with the experimental result. All the studies above are the foundation for accurately describing the 3-D temperature field and optimizing groove.

A radial thrust hydrodynamic sliding bearing (RTHSB) with special shaped cavity had been designed. Taking the instantaneous temperature rise characteristics of RTHSB as an analysis object, considering the influence of inlet lubricating oil velocity and transmission shaft speed, a dynamic simulation method of variable viscosity temperature field is proposed, and the mathematical model of instantaneous temperature rise of time-varying oil film is constructed. The correlation equation between instantaneous temperature rise and oil film variable viscosity is analyzed, the lubricating performance of a special-shaped cavity with variable thickness of the oil film considering real-time full operating conditions is revealed, and the alternating transient laws of oil film thickness with variable viscosity and its instantaneous temperature rise for no-load, heavy-load, and different rotating speeds are studied. It is obtained that the higher temperature area of profiled shaped cavity on reverse flow side extends to oil seal side with increase of rotating speed. The dynamic simulation of variable viscosity of RTHSB with different film thickness is simulated by using FLUENT software and the trend of transient film temperature field distribution of in special-shaped cavity is evaluated. The rationality of the mechanism analysis and numerical simulation results in this paper has been verified.
