Abstract
The Poly Methyl Meth-Acrylate (PMMA) have resilient corrosion resistance and at below zero temperature, their quality expands, thus making it a valuable low temperature polymer. PMMA has discovered its appropriate utility in aviation application. Mostly micro- drilling operation is used to engineer micro-holes in various materials according to their need. The target of this investigation was to streamline micro-drilling parameters, for example, rotational speed, feed given to tool and point angle on the circularity error, thrust force and machining time in micro-drilling on aerospace material i.e. PMMA. The tests were completed according to Response Surface Methodology based L15 orthogonal array. The optimum drilling parameters was determined by using multi-criteria decision making (MCDM) optimization technique. A comparative analysis has been carried out to find out optimal drilling parameters using the two optimization methods
