A super finishing process called Lapping is used to fine finish A390 aluminium material with and without carbon nanotubes and its effect on the material's final surface roughness is analyzed in this work. Experimental results indicate that the surface roughness after lapping is determined by the contour graph and surface roughness tester.Keywords

In the process of identifying part-families and machine groups Fuzzy Cluster Analysis is used to form Machine-part fuzzy relative matrix and then immediately convert it into a zero-one conventional matrix. This paper suggests a method in which fuzzy logic plays a major role throughout by making use of a new similarity coefficient.Keywords

The current trend for any of the Aviation industries is to preserve the strength while reducing the weight so that the aircraft can be more fuel efficient and having more load carrying capacity. CFRP & GFRP composites are common. Carbon fiber mat and Epoxy LY556 were used as constituent materials.Keywords

The aim of this work is to reduce the size of chromium nitrate particles to the order of nano (10-9m) size using the Sol-Gel method, analyze the surface topography of the A390 aluminium specimens by means of SEM, XRD and AFM analysis after nanocoating them using PVD process. Pin on disc apparatus is used to study the sliding wear and friction behaviour of nanocoated and uncoated specimens for bearing application. And finally Response Surface Method (RSM) is used to optimise the process.Keywords
