| Research Abstract |
In the present study, elasticity of grinding wheels is analyzed theoretically and experimentally, and the analyzing method, which can be used for quantitative evaluation of the elastic deformation of whole grinding system under machining process, is proposed. This study consists of three parts, that is, modeling of grinding wheels structure, identification of the amount of static stiffness of bond connecting successive two abrasive grains and analyzing the contact stiffness of grinding wheels with workpiece in grinding process.
In 2000, as the first step of this study, mathematical model of whole grinding wheel is proposed and it is clarified that the relation between the amount of static stiffness of bond and so called Young's Modulus of whole grinding wheel body is analyzed by utilizing finite element method. In this year, based on the static stiffness obtained in 2000, a method to estimate the elastic deformation in contact with workpiece. As the analyzing results, it is made clear that the grinding wheel deformation in contact area can be estimated quantitatively and the elastic deformation of grinding wheel has a non-linear characteristics as same as the previous analysis with the Hertz's contact theory.
