Dynamics of the shaft outer surface form-building on their grinding under condition of non-rigid drive for longitudinal feed

The equations are obtained for the system "workpiece-grinding wheel-electromagnetic mechanism" motion on precise grinding the shafts under the conditions: workpiece shape deviation in cross-section, center orifices shape deviation and non-stiff drive of the longitudinal feed. Solution of the obtained differential equations permits to determine the conditions for precise grinding, among them the parameters of electromagnetic mechanism providing maximal decrease of the error inheritance.
