Description
Summary:Specific frictional forces have been examined for a magnetic abrasive tools as affected by the parameters of the machining in wide magnetic gaps. Such a tools have liquid characteristics and can be considered as viscoplastic medium. The viscosity varies with the cutting speed and when there is any change between laminar and turbulent behavior of the magnetic abrasive particles, in accordance with the Reynolds number. A model representation is used for the tools which forms in large working gaps in the form of conical and spindle-shaped macroformations.[PUBLICATION ABSTRACT]
