In this paper, under such various conditions as shapes and rubber hardnesses of contact wheels, grinding speeds and settings of cut, the tension acting upon the abrasive belt by means of detecting the electrical signal from a strain gauge passed on the inside of abrasive belt is researched experimentally. Moreover, by using the relation between the tension and depth of cut ratio, it is clarified that a selection method from both the shape of the contact wheel and the most suitable ratio of the effective depth of cut to setting of cut under the various grinding conditions are obtained. The main results obtained are follows. (1) It is impossible to get the shape of the contact wheel which has the most suitable ratio of the effective depth of cut to setting cut from the relation between depth of cut and tangential or normal force acting upon the contact wheel in grinding. However, it makes possible to decide the range between the effective maximum and minimum depth of cut ratio by using the tension and suitable shape of the contact wheel can also be obtained from the effective range mentioned above. (2) Considering the relation between the surface roughness of workpiece and the land height of the contact wheel, the surface finish comes to be bad in the contact wheel giving the suitable depth of cut ratio. However, the shape of the con-tact wheel which has the most effective surface roughness and depth of cut ratio must be decided by this method.
