Paper Abstract

A comparatively new micromechanical machining process, semi- magnetic abrasive machining which uses magnetic force as a machining pressure has been developed in ISRO/IIT recently for the precision finishing of cylindrical components. The process is controllable because the machining pressure is controlled by the current that is input to the coil of solenoid, but it needs the monitoring of the surface roughness by controlling the process parameters. For this the surface roughness is predicted as a function of input parameters like rotational sped, magnetic flux density, abrasive grain size, machining duration, and clearance between the workpiece and the poles by a model that has been derived from the removed volume of material. The simulation results are confirmed by comparing them with the experimental results.
