Experimental Study on Slicing of Sapphire with Fixed Abrasive Diamond Wire Saw
Experimental study on slicing of sapphire with fixed abrasive diamond wire saw was conducted in this paper. The process parameters were optimized through orthogonal experiment of three factors and four levels. The effects of wire speed, feed speed and tension pressure on the surface roughness were analyzed. Surface roughness in cutting direction and feed direction were both detected. The result...
متن کاملWafer Slicing and Wire Saw Manufacturing Technology
Wire saw, with its ability to cut very thin wafers from large diameter crystalline ingots of semiconductor materials, has emerged as a leading technology for wafer production in semiconductor and photovoltaic industry. Nevertheless, the wire saw cutting process remains lacking a theoretical methodology and is not properly understood. The modern times compulsion of more accurate and efficient ma...
متن کاملApplication of harmony search algorithm to evaluate performance of diamond wire saw
Evaluation and prediction of performance of diamond wire saw is one of the most important factors involved in planning the dimension stone quarries. The wear rate of diamond wire saw can be investigated as a major criterion to evaluate its performance. The wear rate of diamond wire saw depends upon non-controlled parameters related to rock characteristics and controlled parameters related to ch...
