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...

The process monitoring and mechanics of fixed abrasive diamond wire saw machining are investigated in this study. New techniques to affix diamond particles to a steel wire core have advanced to make this process feasible for the machining of ceramics, wood, and foam materials. Developments in fixed abrasive diamond wire machining are first reviewed. Advantages of using fixed abrasive diamond wi...

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...

Introduction: A bullet type sampler is sometimes used to obtain a sample from an asteroid on samplereturn missions [1]. On the other hand, in-situ analysis is demanded for the investigation of more amount of rock samples. Many drilling or coring devices have been developed [2-5]. Slicing the rock sample is preferable to observe its interior rather than shaving [6]. Because coolant cannot use in...

The wire bow angle is an important factor that affects the shape precision of ingot after diamond sawing process. In this research, angles inside and outside were recorded with a high-speed camera. effects processing parameters such as tension force, feed speed, velocity on analyzed. A numerical simulation model in process presented paper to describe ingot. It was shown smaller than for all par...

Artificial Intelligence (AI) techniques are used for solving the intractable engineering problems. In this study, it is aimed to study the application of artificial bee colony algorithm for predicting the performance of circular diamond saw in sawing of hard rocks. For this purpose, varieties of fourteen types of hard rocks were cut in laboratory using a cutting rig at 5 mm depth of cut, 40 cm/...

The third generation of superhard semiconductor materials, represented by single-crystal SiC, is used widely in microelectronics due to their excellent physical and mechanical properties. However, high hardness brittleness have become bottlenecks development. A diamond wire saw (DWS) has the mainstream tool for sawing hard brittle crystal materials. abrasive consolidated on core through resin o...

Predicting the wear performance of circular diamond saw in the process of sawing hard dimensional stone is an important step in reducing production costs in the stone sawing industry. In the present research work, the effective parameters on circular diamond saw wear are defined, and then the weight of each parameter is determined through adopting a fuzzy rock engineering system (Fuzzy RES) bas...
