A Study on the Prediction of Thermal Deformation Using Temperature Analysis in Surface Grinding Process
초록
The thermal deformation of a workpiece during grinding is one of the most important factors that affect a flatness of a grinding surface. The heat generated in one-pass surface grinding causes the convex deformation of a workpiece. Therefore, the ground durfae represents a concave profile. In the analysis a simple model of the temperature distribution, based on the results of a finite element method, is applied. Theanalyzed results are compared with experimental results in surface grinding. The main results obtained are as follows: (1) The temperature distribution of a workpiece by FEM has a good agreement with the experimental results. (2) The bending moment by generated heat causes a convex deformation of the workpiece and it leads to a concave profile of the grinding surface.
