In this paper, experiments are conducted by machining from different crystallographic orientations of monocrystalline silicon, and the effects of crystallographic orientation on the micro electrical discharge machining (EDM) process are discussed. The results demonstrate that the machining speed and surface roughness are varied when crystallographic orientation changes. The surface roughness is seen to vary by as much as twofold with crystallographic orientation, while the ratio between the maximum and minimum values of material removal rate is 1.76. The unique material removal mechanism of micro EDM enhances the effects of crystal anisotropy on micro electrical discharge machining process.

“…It was found that voltage exerted the most significant effect on the performance characteristics [13]. In order to develop a multivariate statistical tool which can consider all possible technique was propounded [14][15][16]. PCA technique is primarily used to assign weighted values to the output responses so as to determine their relative significance.…”

In the current study, electrochemical machining of Inconel 825, a nickel-based super alloy, was carried out using with tungsten as a tool electrode material and NaCl as electrolyte. The present investigation attaches particular emphasis on explaining mechanism of material removal of Ni-based super alloys in ECM process. The influence of various ECM parameters such as voltage (V), concentration (C) and tool feed (F) has been investigated on evolution of surface morphology of Inconel 825 after ECM. Different performance measures in ECM like material removal rate (MRR), surface roughness (SR) and radial overcut (ROC) have been measured. Grey relational analysis that uses grey relational grade as performance index has been adopted to simultaneously optmise multiple performance characteristics and determine optimal combination of ECM parameters. Moreover, principal component analysis is utilised to determine the weighting values corresponding to various output responses so that their relative importance can be adequately expressed. Optimal condition was found to be V=16V, C=45g/l and F= 0.3 mm/min. Confirmation test was further performed to authenticate the approach applied for determining the optimal conditions which resulted in MRR of Downloaded by [University of Western Ontario] at 12:20 08 February 20152 20.867 mm 3 /min, SR of 0.156 μm and ROC of 0.0697 mm which were superior to those corresponding to all previous experimental runs.
