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

Most grinding problems cannot be solved analytically, therefore extens ive numerical solutions are required by using appropriate numerical te chniques such as the finite element method (FEM). In this study, the w ell-known finite element software, ADINA, was used to predict the phas e transformation of a workpiece subjected to surface grinding. The pro cess was considered to be two-dimensional and the properties of the wo rkpiece material were temperature dependent. To gain practically accep table results, the induced temperature field and the associated phase transformation were analysed by different element meshes. Some efficie nt solution strategies were proposed to obtain reliable predictions fo r different grinding conditions and workmaterial properties. The user coding facilities of the code were used to achieve the above performan ces.
