Zul Shukri Nawawi Modelling of material removal rate on grinding ductile iron using water based SIO2 nanocoolant / Zul Shukri Nawawi Kuantan, Pahang : UMP, 2012 xiii, 32 p. : ill. (some col.) ; 30 cm. + 1 CD-ROM Project paper ( Bachelor of Mechanical Engineering) -- Universiti Malaysia Pahang - 2012 Bibilography : p. 32 This project presents the modelling of the material removal rate on grinding ductile iron using water based silicon dioxide (SiO) nanocoolant using response surface method. The grinding fluids used in this study are conventional coolant and water based SiO2 nanoparticle grinding fluid. The SiO2 nanocoolant is prepared using two step methods. The design of experiment for the grinding process is developed using central composite design method. The method of grinding process is single pass and multiple pass. For the experiment, the parameter has been considered as speed of table and depth of cut. The range of the speed of table is 20-40 m/min and the depth of cut is 20-60 µm. The surface roughness, G-ratio, temperature different, and also material removal rate are selected as the output parameters. The use of central composite design method is use to obtained the prediction model for material removal rate. The analysis of variance has been performed to check the adequacy of the develop mathematical model. It can be seen that the lack of fit for all models are less than 0.005 and R-square value for all model are more than 90 %. Therefore, the mathematical models for conventional and SiO nanocoolant with single and multiple pass grinding acceptable. The obtained results show the better medium for grinding fluid are the conventional grinding in terms of material removal rate however, the surface roughness for conventional coolant is poor compared to the SiO2 nanocoolant.
