This paper integrates the electrochemical turning (ECT)
process and magnetic abrasive finishing (MAF) to produce a combined process that improves the
material removal rate (MRR) and reduces surface roughness (SR). The present study emphasizes the
features of the development of comprehensive mathematical models based on response surface
methodology (RSM) for correlating the interactive and higher-order influences of major machining
parameters, i.e. magnetic flux density, applied voltage, tool feed rate and workpiece rotational
speed on MRR and SR of 6061 Al/Al2O3 (10% wt) composite. The paper also highlights the various
test results that also confirm the validity and correctness of the established mathematical
models for in-depth analysis of the effects of hybrid ECT- MAF process parameters on metal
removal rate and surface roughness. Further, optimal combination of these parameters has been
evaluated and it can be used in order to maximize MRR and minimize SR. The results demonstrate
that assisting ECT with MAF leads to an increase machining efficiency and resultant surface
quality significantly, as compared to that achieved with the traditional ECT of some 147.6% and
33%, respectively.
