“…Tool with mono-crystalline coating seems to perform better than fine-grained diamond-coated tool [32]. Similar work has been conducted by Smith et al, where diamond-coated fibers produced by the chemical vapor deposition on grinding wheel work as abrasive grains [33]. Although, these studies also involved the tool fabrication processes, they are different from our study of fabrication of different geometry tools using specially designed block.…”

With the demand for microstructures of not only with diversified shape but also of reduced dimension on glass, fabrication of polycrystalline diamond (PCD) tool/ microelectrodes with different shape has become important. However, to date, fabrication of different shapes in single setup is not possible and also needs special indexing attachment. To solve this problem, in this study, a specially designed block containing three v-slots of 60°, 90°, and 120°has been designed and fabricated using wire cut. Thereafter with the help of block electro-discharge machining method and using this specially designed block, different shapes of microelectrodes with symmetrical and non-symmetrical section has been fabricated. This study also investigates the feasibility of using these different geometry PCD tool for micro-grinding of BK7 glass. In this context, a relative study on the micro-grinding performance of four different geometry tools (circular, D-shaped, triangular, and square) has been carried out. It has been observed that among the different shaped tools, D-shaped tool experienced lowest cutting force along x-and y-axes where as triangular tool faced lowest force along z-axis, and highest cutting forces were found to be experienced by square tool. Average and maximum roughness of machined surface was found to be improved from circular to others tool except triangular one. But, it was also observed that side surface started to deteriorate from circular to other tool due to edge wear. In case of tool wear, square and triangular tool experienced more wear than circular and D-shaped tool due to their frequent edge blunting or rounding effect. Finally, among four different geometry tools, D-shaped tool was considered to provide better performance in terms of the achieved surface finish, tool wear, and cutting force analysis.

“…Diamond-coated fibers produced by the chemical vapor deposition or coarsegrained diamond were used for grinding work as abrasive grain. 37,38 In the light of what has been written above, it can be understood that many analysts study to find out optimum process parameters for a kind of bond material. However, a few studies have been conducted on comparing two kinds of bond material in grinding.…”

Preparation of grinding wheels is the most important effective factor in glass machining. This article presents the comparison of the iron-and copper-based grinding tools. The performance of the tools is investigated based on technical and commercial aspects using same cutting speeds, feeds, and sizes of diamond grits. Scanning electron microscope is used in order to observe the microstructures of cutting tools. The service life of the grinding tools is determined on the production line in a flat glass plant. A lifetime of Fe-based diamond tools is longer compared to the copper-based wheels. The impact of metal bond materials on the service life is examined. The results show that the Fe-based tools are more economical and more useful for grinding of glass. The holding of Fe-based bonding to diamond grit is stronger than the copper-based ones.

“…In their trial grinding experiments with the β-SiC whisker wheel for die steel SKD11, Yamaguchi et al was able to obtain extremely promising grinding results: surface roughness of Ra 1.5 nm, and grinding ratio of 2200 (above 6000 after dressing). Smith et al coated diamond onto micron-sized tungsten and SiC fibers using the CVD method [5-6] and then radially clamped the diamond fibers using two aluminum discs of 40 mm in diameter and 2 mm in thickness and thus fabricated a diamond fiber grinding wheel [7]. Aurich et al [8] performed the simulation modeling on the grain distribution in the electroplated monolayer wheels.…”

The random nature of the abrasive geometries and their distribution in a grinding wheel results in high specific grinding energy and temperature rise, large grinding forces and large deflection in the grinding system. To overcome the shortcomings encountered in grinding, it is necessary to design a new grinding wheel that is structured in controlled abrasive geometries with preferred spatial positioning and orientation. This paper deals with an experimental research of single fibrous-abrasive grinding of a nanostructured WC/12Co Coating. Prepared by the laser cutting of polycrystalline diamond compact (PDC), the single fibrous-abrasive has the dimensions of 0.3×0.6×10mm. The paper reports the research findings on normal and tangential grinding forces in terms of depth of cut and feed rate and discusses the material removal mechanism of nanostructured WC/12Co Coating ground by fibrous abrasive.
