“…Calculate the normalised S/N ratio (x ij ) using equation (3) to avoid the effect of variability among the S/N ratio (Noorul Haq et al, 2007). Normalisation is performed to diminish the effect of using various units for input parameters and for scaling the data (Adalarasan et al, 2014). The Normalised S/N ratio varies as 0 ≤ x ij ≤ 1.…”

“…A guaranteed reconstruction of original data from a small number of components is possible in PCA and the application feasibility in optimising multi responses in arc welding had shown satisfactory results (Datta et al, 2009). It was also understood that the multi response optimisation was performed by using either PCA in genuine format or as a hybrid with other techniques to find optimality criteria in various mechanical processes (Gauri and Chakraborthy, 2009;Adalarasan et al, 2014).…”

Abstract:The recent trend in miniaturisation of sensors has given micro wire electrical discharge machining (μ-WEDM) a significant amount of research attention. The underlying challenge in the selection of optimal machining parameter combination to achieve the desired surface finish, kerf width and metal removal rate has urged the disclosure of an integrated method of technique for order of preference by similarity to ideal solution (TOPSIS)-based response surface methodology (TOP-RSM). A L16 orthogonal array was used to design the experiments and multi response optimisation was performed by using the TOP-RSM approach. A confirmation test was conducted to ensure the validity of proposed approach. The response surfaces were also studied to understand the effects of individual parameters on the quality characteristics.Keywords: grey Taguchi; TOPSIS; response surface methodology; RSM; manufacturing; micro wire electrical discharge machining; μ-WEDM; optimisation.Reference to this paper should be made as follows: Santhanakumar, M., Adalarasan, R., Senthil Raj, S. and Rajmohan, M.

“…The hybrid technique of grey based PCA can be applied to solve problems with a finite number of options. It combines the merits of both the techniques adopted for prediction of optimal variables [17]. The response surface methodology is a numerical technique employed along with the desirability analysis to find the optimal input condition.…”

Turning is an important machining process involving quality characteristics like tool wear and finish of the cut surface. The present work is focused towards the application of response surface methodology (RSM) in turning of EN24 steel. The work observes the effectiveness of the application of minimum quality lubricant (MQL) during the process of turning EN24 steel. The selection of parameters like tool type, work speed, depth of cut and type of lubrication is vital to obtain a good finish and reduced tool wear. Taguchi's L18 orthogonal array (OA) is used to conduct the turning trials and RSM is applied to predict the optimal turning condition.

“…The polynomial equation developed using RSM can be used to plot the three dimensional surface plots for studying the effects of design parameters on the responses [13,14,15]. The grey relational grade is used as the performance index in grey theory which can be further optimized by using the technique of PCA [16,17,18]. The desirability analysis based on Taguchi's method of experimentation is an economical technique to identify the near optimal setting of design parameters [19].…”

The design parameters and manufacturing technologies involved in the fabrication of composites is a vital advance in the development of materials. The selection of design parameters like matrix material, fillers, volume fraction, curing temperature and treatment play an important role in bringing tailor made properties in the resulting composites. The present work focusses on identifying the proper design parameters for Epoxy/E-Glass composite to enhance its strength. The fabrication trials are based on Taguchi's L9 orthogonal array. Impact strength and tensile strength of the composites are observed for various combinations of design parameters. Grey relational analysis (GRA) properly supplemented by the analysis of variance (ANOVA) is employed to predict the optimal design parameters.
