The constitutive relationship of GH4169 superalloy was investigated. The grinding thermal load acting on GH4169 workpiece in grinding process with conventional aluminum oxide wheel was determined by using the method combining finite element method (FEM) with experiment. The grinding temperature field and grinding thermal residual stress generated in GH4169 were calculated via finite element method (FEM). Finally, the relation between grinding parameters and grinding temperature field and that between grinding parameters and thermal residual stress were discussed.

Grinding Temperature Field

A reasonable finite element (FE) model of grinding temperature field has been developed on the basis of analysis of the transient temperature field， and three kinds of boundary conditions are loaded on the element of a moving heat source. The study, which is based on the finite element principle, has been carried out using the numerical simulation software ANSYS. Many results have been obtained including three dimensional temperature distribution map. The simulated results under different conditions show good agreement with the experimental results. With the comparison of the dry-grinding and wet-grinding, the result shows that the wet-grinding temperature with a proper grinding fluid is rather lower than the dry-grinding temperature. Finally, the variable coefficient of convective heat transfer and the different form heat source have been discussed in detail.

Grinding Temperature Field

By using three dimensions finite element method, the temperature distribution has been simulated in grinding of titanium alloy with SiC wheel. The effects of wheel speed, workpiece speed and tangential grinding force on the grinding temperature field were investigated. The results show that the grinding temperature decreases with the increasing of the workpiece speed, and increases with the increasing of the grinding depth and wheel speed. The obtained results can provide a theory reference for the design and selective of machining parameters during grinding titanium alloy.

Grinding Temperature Field

Temperature is not only an important parameter in machining, but also an important basis for process optimization. Accurate prediction and reasonable analysis of grinding temperature is of great and far-reaching significance to the development and promotion of nanofluid micro-lubrication. In this chapter, the mathematical model of finite element simulation of temperature field of high efficiency deep grinding under four kinds of cooling lubrication conditions is established, and the three boundary conditions and the constraints of simulation model are established, and the mesh division and time step algorithm are determined respectively. Using ABAQUS simulation platform and theoretical model to simulate grinding temperature field, the distribution characteristics of grinding temperature field under different working conditions are analyzed from different directions, different grinding depths, and different workpiece materials.
