Abstract

DHARMALINGAM, S; MARIMUTHU, P  and  RAJA, K. Machinability study on al- 10% tic composites and optimum setting of drilling parameters in electrochemical micro machining using grey relational analysis. Lat. Am. appl. res. [online]. 2014, vol.44, n.4, pp. 331-338. ISSN 1851-8796.

This paper investigates the influence of the process parameters like machining voltage, electrolyte concentration, frequency on the over cut and Material Removal Rate (MRR) on drilling of Al- 10% TiC Metal Matrix composites using Electrochemical Micro Machining (EMM) through taguchi methodology and grey relational analysis. Based on the analysis, optimum levels of parameters were determined and the same to validate through the confirmation test. Experimental results are in close agreement with the developed model. The confirmation results reveal that, there is considerable improvement in Material Removal Rate, Overcut. Grey relational grade are improved by 89.5 %, 57.9% and 95.16 % respectively. It is observed that the machining performance can be effectively improved with respect to initial parametric setting
