Abstract:
Based on the analysis of problems of diamond cut-off wheels used in slot grinding of ceramics at present, a brazed diamond cut-off wheel was produced and analyzed. Two typical advanced ceramics, alumina and silicon nitride, were used as the workpiece materials. In the experiments of slot grinding of ceramics, grinding ratio, wear process of the wheel and grinding quality of the work were studied. Experimental results showed that the brazed diamond cut-off wheel obtained good grinding ratio and abrasive resistance. The surface roughness of ground silicon nitride was better than that of alumina.

Abstract:
In this paper, noise of diamond circular saw blades has been measured, five different types of saw blades are used to measure their noise under different working condition. By analyzing of the experimental results, the effect of different factors on the saw blade noise is studied. The result shows that the increasing the speed of cutting machine or the diameter of blade, noise will become larger. The noise of saw blade with a hole or water slot would be greater than others without any hole or water slot.

Abstract:
In this paper, a new configuration of dual-band, dual-polarized microstrip antenna applicable to mobile base stations is proposed. The concept behind the new design is the use of an artificial magnetic conductor (AMC) structure that operates in the required two bands beneath a radiating diamond shaped slot. The choice of the diamond-shaped slot is due to its support of an infinite number of resonant modes where the dimensions of the diamond shape have more degree of freedom that controls the excited modes when compared to the rectangular slot. The proposed antenna works over the 870–960 MHz (G

Abstract:
A design of mobile-phone antenna array with diamond-ring slot elements is proposed for fifth generation (5G) massive multiple-input/multiple-output (MIMO) systems. The configuration of the design consists of four double-fed diamond-ring slot antenna elements placed at different corners of the mobile-phone printed circuit board (PCB). A low-cost FR-4 dielectric with an overall dimension of 75 × 150 mm2 is used as the design substrate. The antenna elements are fed by 50-Ohm L-shaped microstrip-lines. Due to the orthogonal placement of microstrip feed lines, the diamond-ring slot elements can exh

Abstract:
The endless diamond wire saw was developed using complex electroplating method. The sawing process on granite was experimented. The effects of diamond grain size, feed load, wire speed, and granite properties on sawing process were investigated. It is proved that the edges of sawing slot of granite were regulative and the cutting surfaces were smooth. The cutting efficiency could be improved by increasing the diamond grain size, wire speed, and feed load. However the increase of the feed load would induce higher tangential cutting force, and the case of the effect of wire speed was reversed.

Abstract:
The research and manufacture of endless diamond wire saws have been reported in this paper. The matrix of saws was 65Mn steel wire whose diameter was o.8mm, and was welded as a ring by argon arc welding. The endless diamond wire saws were made by setting diamond abrasives on endless steel matrixes using nickel-plating method. The cutting experiments were carried out using the diamond wire saws on the homemade test equipment. The characteristics of the saws are narrow slot, high cutting speed, low noises and good surface quality. The surface cut could be finishing grinding or polishing directly

Abstract:
Recently, a new method for residual stress measurement in thin films by using the focused ion beam (FIB) has been proposed by the authors. It is based on the combined capability of the FIB imaging system and of high-resolution strain mapping software (VIC-2D). A simple equation based on two-dimensional elasticity is used to evaluate the residual stress from the displacements due to introducing a slot. The slot length is assumed to be much larger than the slot width or depth. And the effect of the slot width was neglected. However, it is often hard, depending on film materials, to introduce a n

Abstract:
The shape of the tuning stub of the wide slot printed antenna is an important factor which affects the antenna’s performances. In this paper, a new design and optimization method of wideband printed slot antenna using a shape blending algorithm is presented. The proposed antenna consists of a wide rectangular slot and a tuning stub, whose profile is formed by the shape blending outcome from a pie and a diamond shape. The method is used to design an ultra-wideband antenna. The impact on the impedance bandwidth through the antenna geometry change with the different shape blending results has bee

Abstract:
In this paper a novel configuration of broadband multi slot antenna for C/X bands is presented and analyzed. By cutting two diamond slots in the middle of the rectangular patch and three triangular slots in the right side of the patch, resonances can be created. Microstrip feed line is used in the down side region of the patch. Antenna characteristics were simulated using a finite element method (HFSS). According to simulations, the proposed multiple slot antennas can provide two separated impedance bandwidths of 970 MHz (about 11.96% centred at 8.11 GHz band) and 890 MHz (about 9.76% centred

This paper presents the research on the machinability studies in micro-milling of (001) silicon wafer. Excessive generation of undesirable surface and subsurface damages such as surface edge chipping often occurs when machined at depth of cut of several hundreds of microns. Ideal machining strategy to reduce the generation of edge chipping is required. Investigations on the effect of machining conditions on the cutting performances and size effect on the specific cutting energy in silicon micro-milling were conducted. These investigations provide understandings on the behavior of cutting mecha
