Abstract

Both internal spherical surface grinding and external spherical surface grinding require the application of specific kinematics of the grinding process. In this paper a study is made of the dimensional interrelations between the ground surface diameter and the crossing angle of the tool and workpiece axes as well as the grinding wheel dimensions. A definition is also proposed for the effect on the grinding wheel axial wear of the size of the slot between the grinding wheel and the ground socket. The effect is shown of the rigidity of the wheelhead on the quality of the ground spherical surface. In test results presented here particular attention has been given to defining the dependence of the grinding wheel axial wear rate and the material removal rate (linear) on the radial feed rate and the grinding wheel peripheral speed as well as the effect on the quality of the spherical socket ground surface.
