“…Chemical Vapor Deposition (CVD) diamond is renowned for its exceptional hardness, wear resistance, high thermal conductivity, and stable chemical properties. Dressing tools made with CVD diamond instead of natural diamond have been widely used for dressing wheels in recent years due to their stable dressing parameters and long service life [1,2]. CVD diamonds are typically bonded to the substrate through sintering or electroplating when producing CVD rotary dressers.…”

Dressing wheels with CVD rotary dressers are widely used in the grinding process. To meet the accuracy requirements of dressing grinding wheels, the profile accuracy of CVD rotary dressers must be processed to the micron level. However, CVD diamond is a hard and brittle material, making it difficult to machine to a high degree of shape and dimensional accuracy. A graded grinding method is proposed in this paper to achieve precision machining of the CVD rotary dresser. The normal residual error is calculated by measuring the difference between the actual grinding profile and the target profile along the normal direction first, and then graded compensation processing is carried out based on the magnitude of the normal residual error. In the grinding process, it is proposed that the grinding path be planned according to the real-time profile of the grinding wheel. Experiments on a CVD rotary dresser for the NILES ZP 12 gear grinder showed that the profile accuracy (Peak to Valley, PV) of the CVD rotary dresser was improved from 14.79µm to 1.57µm after grinding. The fluctuation of the arc radii of CVD diamonds in different phases along the circumferential direction was reduced from 0.0117mm to 0.0019mm.

“…Grinding is an abrasive-assisted material removal process commonly employed for the final shaping and surface treatment of components made from various engineering materials [9]. Typically implemented in the later stages of the manufacturing cycle, grinding ensures the attainment of desired precision within specified tolerance limits and accounts for approximately one-fourth of the total machining costs [10][11]. In various subtractive manufacturing processes, grinding exhibits dynamic characteristics wherein numerous rigid abrasive particles interact with the work surface, ultimately effecting material removal through the generation of numerous ultra-fine scratches.…”

In the processing of hard and brittle materials such as silicon nitride (𝑆𝑖 3 𝑁 4 ), machining is often accompanied by numerous shortcomings which lead to poor processing efficiency. In order to enhance the grinding efficiency of silicon nitride ceramics, the material's strength is weakened through a 355 nm nanosecond pulsed laser for generating microscale textural patterns on ceramic surfaces. This paper investigates the influence of overlap rate on the material surface and the scratching characteristics of single diamond abrasive grains on the grooved and cratered surfaces to elucidate the material removal mechanism of the textured surface. Experimental results indicate that the time series of laser ablation depth follows fractal geometry, and the laser ablation products primarily consist of a mixture of silicon and silica. Laser-induced surface texturing facilitates a transition in the material removal mechanism from a mode dominated by plastic flow to a mixed mode involving both brittle fracture and plastic flow. In contrast to grooved surfaces, cratered surfaces demonstrate diminished fracture impact regions and lower acoustic emission signal values, thereby making them more suitable for machining operations under high levels of scratching force.
