Summary: The rotating ultrasonic-assisted grinding (RUAG) experiment introduced intermittent pit-shaped micro-texture on the workpiece surface, reducing thermal damage and improving lubrication compared to conventional grinding (CG). This study aimed to understand the formation mechanism of micro-texture by establishing a mathematical equation for grinding depth based on the theory of micro-debris volume. Response surface analysis was conducted to analyze the relationships between macroscopic grinding depth, micro-texture feature parameters, and machining parameters. Single-factor experiments and simulations verified the theoretical micro-texture features.

Summary: The study compared the material removal mechanism in Ultrasonic Assisted Grinding (UAG) and Conventional Grinding (CG) for SiC, finding a transition from ductile removal to brittle fracture with increasing undeformed chip thickness. Additionally, UAG showed lower surface/subsurface breakage, surface roughness, grinding force, and specific grinding energy compared to CG under identical operating conditions.

Summary: In this paper, a novel three-dimensional surface topography model of original CVD diamond grinding wheels was established based on multiple random data. The model was simulated to analyze the grinding process and its performance was verified through grinding experiments. The influence of grinding parameters and wheel wear on the grinding performance was discussed, and micro-structured CVD grinding wheel models were presented by coupling different forms of micro-structures. These findings provide a quantitative and effective method for the design of CVD diamond grinding wheels and their surface structuring.

Summary: The study proposed a brazed diamond grinding wheel with defined grain distribution to improve the machining performance, showing that under similar operating conditions, the brazed grinding wheel generated smaller grinding force, smoother ground surface, and lower surface roughness compared to the electroplated grinding wheel. Additionally, the ultrasonic assisted grinding reduced grinding force, force ratio, surface roughness, and profile wave height compared to conventional grinding, but also caused a more extensive ultrasonic vibration effect on grinding.

Summary: This study established a collision number model and analyzed the influence of different dressing parameters on the ultrasonic roller dressing mechanism of V-CBN grinding wheel. The experimental results showed an inverse relationship between the collision number and the surface roughness and runout of the workpiece.

Summary: The study investigated the grinding performance of TiC-Steel cermet using a customized vitrified bond cBN wheel. Results showed that the main removal modes of TiC-Steel cermet are plastic removal of steel phase and brittle fracture of ceramic phase. Surface roughness parameters increase with grinding depths and decrease with spindle rotation speed, with feed rate having less impact on surface quality. Optimal processing parameters were determined to achieve the best surface quality and lowest grinding force.
