“…However, there are actually two different approaches in ECDM, namely, ECM and EDM. In ECDM, ECM dressing first anodic dissolves the bond layer and hence exposes a higher grain protrusion (Schopf et al 2001;Kramer et al 1999;Nebashi et al 1998), and then EDM truing and dressing produces much smaller grain protrusion than the ECM process but it is of high macro-geometrical accuracy, which therefore is obviously very suitable for the dressing and truing of metal-bonded grinding wheels (Syoji et al 1990).…”

Grinding is a typical machining process which utilizes a grinding wheel consisting of abrasive grains held together with a binder material. The material removal action is done by the masses of tiny and sharp abrasives directly. Therefore, the good condition of grinding abrasives and wheel is very important to achieve good grinding performance. Thus, it is necessary to perform the conditioning (including both the dressing and truing processes) of grinding wheel. Generally, it is relatively simple to achieve the conditioning of conventional grinding wheel. But it is not the case for the superabrasive and wheels, which some novel dressing and truing methods and equipment are needed and

“…Examples included developing new truing and dressing techniques (also including laser dressing) [107][108][109][110][111], optimizing input parameters through characterization of truing and dressing processes to produce an ideal wheel surface topography [105,112,113], and evaluating dressing quality or wheel sharpness by means of directly measuring wheel topographic parameters such as the number of cutting edges, the height of grain protrusion, and the average roughness of the wheel surface after dressing [114][115][116] or correlating wheel sharpness to grinding power, acoustic emission (AE) signal, residual stresses, or air flow rate along the wheel periphery [117][118][119][120][121]. Based on these reviewed literatures (e.g., [105][106][107][108][109][110][111][112][113][114][115][116][117][118][119][120][121], it is known that the application of SiC abrasive tools, as dressing tools, is much limited due to high wear and is time consuming in dressing CBN wheels. For this reason, besides the laser dressing, the mechanical truing/dressing with diamond abrasive tools, instead of SiC tools, is the most popular method for the recovery of grinding capabilities and wheel geometry of worn grinding wheels in the present days.…”

This paper provides a state-of-the-art review on the investigations into the residual stresses in metallic structural materials generated by grinding. The materials covered include steels, titanium alloys, and nickel-based superalloys. The formation mechanisms of the residual stresses and their impacts are specifically discussed. Some major influential factors on the residual stresses formation in grinding, such as grinding wheel characteristics, dressing techniques, grinding parameters, cooling conditions, and properties of workpiece materials, are analyzed in detail. These include experimental measurement, modeling, simulation, knowledge-based monitoring, and fuzzy analysis. Finally, the paper highlights some important aspects of grinding-induced residual stresses for further investigation.

“…In addition to stylus-based measurements, non-contact measurements have also been used. Shoji et al [ 12 ] measured the amount of protrusion of abrasive grains by stereo-photography and investigated the effect of this amount on grinding performance. Laser-based, non-contact measurements can be used to obtain the distribution of the grinding wheel outer surface heights with high accuracy [ 13 , 14 , 15 ].…”

Determining Surface Topography of a Dressed Grinding Wheel Using Bio-Inspired DNA-Based Computing

et al. 2021

Grinding is commonly used for machining parts made of hard or brittle materials with the intent of ensuring a better surface finish. The material removal ability of a grinding wheel depends on whether the wheel surface is populated with a sufficiently high number of randomly distributed active abrasive grains. This condition is ensured by performing dressing operations at regular time intervals. The effectiveness of a dressing operation is determined by measuring the surface topography of the wheel (regions and their distributions on the grinding wheel work surface where the active abrasive grains reside). In many cases, image processing methods are employed to determine the surface topography. However, such procedures must be able to remove the regions where the abrasive grains do not reside while keeping, at the same time, the regions where the abrasive grains reside. Thus, special kinds of image processing techniques are needed to distinguish the non-grain regions from the grain regions, which requires a heavy computing load and long duration. As an alternative, in the framework of the “Biologicalisation in Manufacturing” paradigm, this study employs a bio-inspiration-based computing method known as DNA-based computing (DBC). It is shown that DBC can eliminate non-grain regions while keeping grain regions with significantly lower computational effort and time. On a surface of size 706.5 μm in the circumferential direction and 530 μm in the width direction, there are about 7000 potential regions where grains might reside, as the image processing results exhibit. After performing DBC, this number is reduced to about 300 (representing a realistic estimate). Thus, the outcomes of this study can help develop an intelligent image processing system to optimize dressing operations and thereby, grinding operations.
