On the Elastic Modulus of Abrasive Stones

Study on the Mechanical Properties of Grinding Wheel (1st Report)

Abstract

In this report, as one of the study on the elastic modulus of grinding wheel, the correlation between the elastic modulus E_R measured by the ultrasonic forced vibration method which give the dynamic forces and the components of abrasive stones is discussed. And then, the elastic modulus E_P and E_S are respectively measured by the ultrasonic pulse method with the semi-dynamic forces and the compression test with the static forces. The differences in the elastic modulus obtained by these methods are also discussed.
A summary of the results is shown below.
(1) The elastic modulus is influenced on the volume rate of abrasive stone's components.
(2) The correlativities between the abrasive stone's components and the elastic modulus E_R, E_P are better than E_S. And the elastic modulus E_R agrees very well with E_P, but E_S is slightly different from the others.
