THE FINITE-ELEMENT THERMAL-ANALYSIS OF GRINDING PROCESSES BY ADINA

Most grinding problems cannot be solved analytically, therefore extensive numerical solutions are required by using appropriate numerical techniques such as the finite element method (FEM). In this study, the well-known finite element software, ADINA, was used to predict the phase transformation of a workpiece subjected to surface grinding. The process was considered to be two-dimensional and the properties of the workpiece material were temperature dependent. To gain practically acceptable results, the induced temperature field and the associated phase transformation were analysed by different element meshes. Some efficient solution strategies were proposed to obtain reliable predictions for different grinding conditions and workmaterial properties. The user coding facilities of the code were used to achieve the above performances.
