Machining Accuracy

Swirling Fluidized Bed Polishing (SFBP) is a non–traditional alternative abrasive flow surface finishing form of Fluidized Bed Machining (FBM) in which the former has special features to overcome certain significant limitations of the latter, namely the variation of the surface roughness vertically along the component surface and the screening effect owing to the complex contours in the work piece geometry. Owing to its ability to perform machining and generate polished surface from a roughness value of Ra 1.2μ to 0.2 μ within 8 hours of processing, this new method offers greater scope in the surface modification of rough machined surfaces with complex geometry such as component with ducts and grooves. This research focus on investigating the effect of abrasive particle concentration on metal removal rate per unit area of the specimen surface. 3D surface morphology analysis investigates the quality of the polished surface and the study of circumferential uniformity and machining accuracy analysis on a complex-contoured component further investigate its scope and relevance in industrial applications.

Reinforcing Filler

The surface modification of corn starch and the use of modified starch as reinforcing filler partly replaced carbon black in rubber composites were studied. The surface of starch was modified with 3, 4-2H-dihydropyran and maleic anhydride by grafting reaction in organic solution, that is, the process of etherification and the esterification of the starch. The structure of the ether ester starch was investigated by FTIR, SEM. Based on the results of the mechanical and heat building up properties of composite, it is showed that using modified starch as reinforcement filler filled into the rubber partly replaced CB, the characteristics of high flex life and low heat building up for composite can be obtained.
