This project presents the modelling of the material removal rate on grinding ductile iron using water based silicon dioxide SiO 2 nanocoolant using response surface method. The grinding fluids used in this study are conventional coolant and water based SiO2 nanoparticle grinding fluid. The SiO 2 nanocoolant is prepared using two step methods. The

MODELLING OF MATERIAL REMOVAL RATE ON

The basic process of mechanical specimen preparation is material removal, using abrasive particles in successively finer steps to remove material from the surface until the required result is achieved. There are three mechanisms for removing material grinding, polishing, and lapping.

Metallographic grinding and polishing insight

Dec 14, 2004 Methods using supercritical fluids are also powerful for the synthesis of nanoparticles. For these methods, the properties of a supercritical fluid fluid forced into a supercritical state by regulating its temperature and its pressure are used to form nanoparticles by a rapid expansion of a supercritical solution.
