Abstract
The objective of the present research is to reveal the capability of
adapting a small lathe to an electrochemical turning machine and adding
a small mechanism for rotating electrode, Also the use of segmented tool
for pulsating current without the need for using pulsed current generator
for improving the accuracy and the performance of the process. A
theoretical analysis for estimating the allowable feed rate has been
presented to explain the mechanism of the process. Equations for
predicting current density and metal removal rate in machining zone have
been also derived. A locally adapted test lathe has been constructed for
performing experimental tests.
The experiments were divided into two groups, the first group has
been performed for electrochemical turning with rotating electrode (ECTRE)
and the second group has been performed for pulsed electrochemical
turning with rotating electrode PECT-RE.
The central composite second order rotatable design (CCD) has
been utilized to design the experiments and response surface
methodology (RSM) has been also employed to develop the experimental
models. Analysis of machining characteristics of ECT has been submitted
based on the developed models. In ECT-RE the effect of working
parameters namely; applied volt, feed rate, tool workpiece speed ratio and
tool diameter on metal removal rate (MRR), surface roughness (RA) and
roundness error (RE) have been analyzed through RSM. In PECT-RE the
effect of working parameters namely; applied volt, feed rate, tool
workpiece speed ratio and current frequency on MRR, surface roughness,
and roundness error have been analyzed through RSM. Comparisons
between ECT and PECT responses lave been performed.
