    Applied mechanics in grinding—III. A new formula for …

    Abstract The contact length between a grinding wheel and a workpiece during operation is one of the principal factors that specify thermal and mechanical deformation of the workpiece. In this paper, we first propose a new formula for the contact length prediction, present a simple criterion to determine the applicable range of any approximate formulae, and then carefully compare our formula ...

    Abstract This paper proposes modelling methods of the elastic modulus of grinding wheels and the interface forces over the contact arc between a wheel and a workpiece during grinding operation. It reveals that, for a class of grinding wheels with same types of grain and material, the elastic modulus is only a function of dimensionless temperature and a governing non-dimensional variable ...
