| Summary: | 碩士 === 國立臺北科技大學 === 機械工程系機電整合碩士班 === 106 === The Surface inspection of Ni/diamond composite coating is important for high quality electrodeposited Ni–diamond wires. Ni-coated diamond abrasive wire saw are widely used for cutting hard and brittle materials effectively. Diamond abrasives have coated with nickel on the surface by chemical plating in advance and deposited on the steel wire through electroplating. The abrasives deposited density and uniformed distribution on sawing wire surface are the key factors for sawing efficiency. Electrodeposition was carried out from a conventional nickel sulfamate bath. In this study, we have developed a machine vision based inspection system for measuring the profile of abrasives coated on wire saw surface. In this configuration, the proposed detection algorithm can calculate the amount of single and aggregated abrasives precisely.
The 2D dimension of the wire saw include wire diameter, nickel thickness and protrusion height of abrasives are also measured, and the defect of abrasives coated are detected simultaneously during the electrodeposited process. The analyzed result is beneficial to the electrodeposited process to adjusting the plating parameters and the concentration of diamond particles in the plating bath timely.
