The Wire

The paper presents results of measurements of surface roughnessof clear, colorless sapphire (Al2O3 – corundum modification,aluminum oxide) crystal cut by diamond wire. The diamond wirecutting machine RTS 440 was used for research. Only verticalfeedrate of wire was varied while the wire speed, tension, cuttingmethod and cutting angle were constant. Results are presentedas graphs of dependence of arithmetic average surface profiledeviation Ra on feedrate of the diamond wire. Sapphire plateflatness measurement results are presented as well. Sapphire platecutting time dependence on feedrate of the wire was established.The most optimal feedrate range was obtained.

Aim. Developing the theory of diamond wire cutting of crystalline rocks for separating the facing stone blocks from the array by establishing links between individual geometric parameters of the side and the cutting process. Research methods. To achieve this aim were used the next method: analytical studies of the relationship between the geometric parameters of the process of diamond wire cutting, experimental study of the same geometric parameters of the process of diamond wire cutting of high-strength rocks to confirm or refute previously obtained analytical relationships, and statistical processing of data. Results. The length of contact of the diamond wire with the rock is an important criterion for the process of separating the blocks of facing rocks from the array. Given the unavailability of the diamond wire side in the array for direct measurement methods, there is a need for indirect determination of the contact length. It is proposed to use the length of the free section of the wire, as the total length of the wire remains unchanged during the cutting process. It is assumed that the length of the free section can be estimated by the distance between the diamond wire machine installation and the slope of the ledge. Analytical dependences between the specified sizes are considered. The existence of the obtained dependences and the strength of the correlation connection was confirmed by experimental studies in the conditions of the block quarry of the facing stone. Scientific novelty. At first time, the relationship between the distance of the diamond wire machine installation and the side of the diamond wire and the length of the free section of the diamond edging, which allows to control the length of contact of the diamond wire with rock in the cut. The obtained dependence is analyzed and it is concluded that the geometric parameters of the ledge will affect the length of the cut only in the initial stages of separation of the block of natural stone from the array. In the next stages, the length of the free section of the diamond wire depends only on the distance of the location of the diamond wire machine installation and the side of the diamond rope. Practical significance. The value of the optimal initial distance of the diamond wire machine placement to the slope of the ledge is found. The empirical dependence of the length of the free section of the diamond wire on the location of the diamond wire machine is also obtained

Processing Water

Method of processing water-soluble potassium dihydrogen phosphate (KDP, KH2PO4) crystal is presented in this article. Diamond wire cutting machine “RTS 440“ was used for cutting. Only one of cutting parameters – vertical feed rate of diamond wire – was varied during experiments. Other cutting parameters (speed and strain of wire, cutting method, cutting angle) were constant. Original kerosene cooling system was designed and produced. Results are presented as graphs of dependence of arithmetic average surface profile deviation Ra of KDP and cutting time on vertical feed rate. Optimal interval of feed rates was obtained.

The Wire

Abstract This study attempts to develop a machine tool to let its cutting function and precision be able to compare with the counterpart of the wire-cut electrical discharge machine, and also can cut non-conducting materials. This machine tool is numerically controlled by a PC-based controller to cut some projected shapes defined on a single axis, dual axes or multiple axes. This machine is to use one diamond wire loop with motion in direction of Z-axis or a certain direction, to attain the function of cutting. The wire could be kept as straight as possible at the cutting zone and not to shift laterally from the feeding direction. Besides, a tension sensor based on CCD cameras is also installed to know the cutting force and reactions of the workpiece against the diamond wire so as to adjust the wire travelling speed and feedrate of the workpiece to cut the corner precisely.

Abstract A diamond wire saw was modified for cutting thin sections of frozen soil and suitable operating conditions were determined experimentally. It was found that a lubricated wire, 0.34 mm in diameter, operaied at cutting velocities of 100-300 mm s-1 and cutting forces 0.02-0.1 kg produced smooth cut surfaces un thin sections 0.4-0.5 mm in thickness. The; temperature and wire size were not critical operating parameters and the wire tensions recommended by the manufacturer were satisfactory. A method of mounting the thin sections is also described.
