Abstract
This paper describes the development of a new process termed as electro-discharge diamond drilling (EDDD) for making the holes in difficult-to-cut aerospace materials and validated with the newly developed hybrid approach of models for material removal rate (MRR), average surface roughness (Ra), and average circularity (Ca). The developed model consist of Taguchi methodology (TM) coupled with response surface methodology (RSM) and has been termed as TMRSM. The model correlates the effects of interactions as well as of higher order of considered input parameters of tool electrode rpm, gap current, pulse-on time and duty factor. Thereafter, multi-objective optimisation (MOO) of the EDDD parameters has been done with the combination of grey relational analysis (GRA) and principal component analysis (PCA) methodology and termed it as GRAPCA. The used hybrid EDDD process of machining along with using the hybrid approach of TMRSM as well as GRAPCA methodology for modelling and MOO is successful.
