“…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.

“…Thermal analysis of the cooling process in laser assisted dressing of alumina wheels suggests the generation of preferable multifaceted grains, which favors the cutting action [13,14]. Touch dressing of electroplated diamond wheels is also made possible using an ultra-short pulsed picosecond laser [15,16]. The application of ultra-short pulsed lasers for the conditioning of superabrasive tools has also been reported in literature [17,18].…”

Abstract. Laser ablation is a novel non-mechanical wheel preparation method for optimizing the treatment costs of superabrasive tools. In this study, the thermal e ects of picosecond laser radiation on vitri ed and resin bond CBN superabrasive grinding wheel surfaces were analytically and experimentally investigated. The analytical approach was intended to nd threshold process parameters for selective ablation of cutting grains and bond material. A picosecond Yb:YAG laser device was integrated with a cylindrical grinding machine, which facilitated the treatment of grinding wheel as it was mounted on the grinding spindle. It is shown that the extent of material ablation is de ned by the maximum surface temperature induced by the laser radiation, which is in turn de ned by the laser pulse energy. It is also suggested that the depth of laser thermal e ects is governed by the relative speed of the laser scanner with respect to the wheel surface.

“…However, after more than 20 years of development, laser dressing remains in the experimental stage, and the number of researchers and published results in this field are limited. Based on statistics compiled by our group (from searching the Web of Science database), only 15 research organizations in six countries (India [1][2][3][4], Germany [5][6][7], China [8][9][10], USA [11][12][13], Switzerland [14][15][16], and Iran [17]) have been developed, and approximately 30 SCI publications on laser dressing have been published (including auxiliary laser dressing).…”

Coarse-grained bronze-bonded diamond grinding wheels dressed using lasers and silicon carbide dressing wheels were used to grind YG8-cemented carbide workpieces. The wear patterns and grinding ratios of the laser-dressed grinding wheels were investigated after different grinding stages. After grinding, the laser-dressed grinding wheel displayed superior surface topography compared to the silicon carbide wheel, and the surface quality of the workpiece also improved. The minimum surface roughness of the workpiece was 0.425 μm. In the initial wear regime, the primary mechanisms included abrasive wear and grain removal. The grinding ratio was approximately 205.4, and the surface roughness of the workpiece after grinding was 0.314 μm. In the steady-state wear regime, abrasive wear was the primary mechanism of wearing, while minor amounts of grain removal and bond wear were observed. The grinding ratio was approximately 405.1, and the surface roughness was 0.337 μm. In the accelerated wear regime, the primary mechanisms were grain removal, abrasive wear, and bond wear. The grinding ratio was approximately 96.0, and the surface roughness was 0.454 μm.
