Circular sawing with diamond-impregnated tools has been extensively used in stone processing plants and prediction of rock sawability is important in the cost estimation and the planning of the plants. Rock sawability depends on machine characteristics, type and diameter of diamond saw, depth of cut, rate of sawing and tool wear, and rock properties. Some researchers have investigated the relat...

A review of the scientific literature reveals little research on the ergonomics of handsaws and no literature on the specific challenges of arborist saws (saws for cutting and pruning living trees). This study was designed to provide some insight into the effects of saw design and height of sawing activity on the biomechanical response of the upper extremity. Eighteen participants performed a s...

The majority of solar cells produced today are made with crystalline silicon wafers, which are typically manufactured by growing a large piece of silicon and then sawing it into ~200 pm wafers, a process which converts one-half of the high-purity silicon into waste sawdust. To bypass the sawing process, a new method for making high-quality multicrystalline wafers without sawing is under develop...

The escalating construction industry has led to a drastic increase in the dimension stone demand in the construction, mining and industry sectors. Assessment and investigation of mining projects and stone processing plants such as sawing machines is necessary to manage and respond to the sawing performance; hence, the soft computing techniques were considered as a challenging task due to stocha...

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...

This work deals with a sawing task performed by two cooperating arms. For the sawing task to follow a line in a horizontal plane, three directional motions have to be controlled (i. e., two translational motions and one rotational motion). A [so, a certain level of force has to be controlled toward the vertical direction not to loose the contact with the object to be sawn. The two-arm system un...

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...
