“…Pulsed laser irradiation is a processing method based on a thermal effect, and the resulting thermal effect is determined by laser parameters such as the laser energy density, pulse frequency, duty cycle, and peak power as well as the physical parameters of the bronze bond and abrasive particles [8]. Figure 2 depicts the energy deposition on the bronze bond surface, where t 1 is the time at which the bronze bond absorbs enough energy to reach the removal threshold, and t is the time at which the pulsed laser begins to irradiate.…”

“…In the study of phase explosions, the laser power density I is a critical technical parameter [8]. It is closely related to the bond material deconstruction and removal efficiency as well as to the removal method (liquid phase, gaseous phase).…”

“…A scanning electron microscope was used to observe the microstructure of the grinding wheel surface before and after the laser dressing, and the removal mechanism of various bond materials on the grinding wheel surface using a laser was analyzed. Chen et al [6][7][8]10] used a fiber laser to conduct an extensive dressing experiment study on a superhard abrasive grinding wheel, and they observed the grinding wheel surface quality and topography after laser dressing. They confirmed that after laser dressing, the melted material on the grinding wheel surface blocked the crater, affecting the grinding wheel performance.…”

This paper presents a theoretical analysis of the surface bond removal mechanism for bronze-bond diamond grinding wheels using a pulsed laser. For the first time, the existence of a phase explosion phenomenon during the process of grinding wheel laser dressing is proposed, and the negative effects of a phase explosion on laser dressing are analyzed. Additionally, a theoretical study on phase explosion is conducted. The mechanism of bronze-bond diamond grinding wheel laser dressing is improved, and theoretical guidance for bronze-bond diamond grinding wheel laser dressing is provided. In the experiment, the processing parameters of the laser during phase explosion are studied, and a grinding test under the corresponding conditions is conducted. A highspeed camera is used to observe phase explosion in the laser dressing process. An ultra-depth 3-D microscope system is used to observe the topography of the bronze-bond diamond grinding wheel after dressing and grinding as well as the bronze wheel surface quality. It is concluded that to avoid phase explosion from occurring in the laser dressing of the bronze-bond grinding wheel, chip space around the bond must exist for the abrasive particle protrusions. The processing parameters of laser dressing under certain condition are optimized, and the desired dressing effect is achieved.

“…Semak and Matsunawa [3] proposed a new one-dimensional steady-state ablation model, which takes into account the influence of melt flow on heat conduction. The team of Chen [4,5] conducted a series of experimental and theoretical research studies on laser ablation of a super-abrasive grinding wheel and M a n u s c r i p t 2 calculated the pit depth in single-pulsed laser ablation by simulation. Presently, little research has been conducted on heat transfer equations for multipulse laser ablation of materials.…”

“…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.
