“…It is evident from the higher grinding ratio and high MRR. 12 Wheel loss of brown wheels was much lesser when compared with wheel loss of white wheels. This study is henceforth narrowed down to brown wheels with a bond A, and their performance is evaluated in a cylindrical grinding machine, as shown in Table 3.…”

The performance of a grinding wheel is greatly determined by its structure which in turn is influenced by the characteristics of the bonding material. Vitrified bonds were used in 50% of the wheels, which are mixtures of clay, feldspar and fusible materials. Vitrified wheels were fired at temperatures >1270°C. The main aim of this work is to focus on the feasibility of a low melting bonding material that would render the wheels a better or comparatively closer performance level than that of the conventional wheels, thereby attempting to reduce fuel and time consumption. Suitable low melting bonds were chosen based on the results of fusibility tests and chemical analysis, and their properties such as density, sound index (SI) and Young's modulus (YM) were evaluated. Performance characteristics were investigated through a cylindrical grinding test and compared along with the standard wheel. Attempts have been made to reduce the size of bonds to improve their properties, and the results obtained were promising.

With the rapid development of processing technology, increasing processing efficiency is no longer the only goal but also the utilization of green and clean manufacturing procedures is required. In this context, the development of an efficient processing strategy for ceramic matrix composites (CMCs) is of great importance. Although SiCf/SiC composites are regarded as one of the most novel fiber-reinforced ceramic matrix composites, their processing is quite difficult. Along these lines, in this work, the orthogonal test of single-grain scratches was conducted under different lubrication modes. From the acquired results, it was demonstrated that compared with the dry type, the minimum quantity lubrication (vegetable oil) lubrication method exhibited the best effect, the scratch force was reduced by 48.3%, and the surface uplift height was reduced by 48.4%. The dominant mode of material removal of the SiCf/SiC composites was a brittle fracture, and the damage characteristics mainly included natural fiber fracture, matrix breakage, fiber pullout, and fiber exposure. In addition, the scratch depth and the scratch angle are the key factors affecting the processing quality. Increasing the processing ratio of 0° and using MQL (vegetable oil) have yielded the best results.

“…Zhang et al [21] also found that ultrasonic vibrations effectively reduced the machined surface roughness by 9% compared with conventional grinding. Ping et al [22,23] discovered that increasing the grinding wheel speed improved the surface quality and reduced the machined surface roughness. Wang et al [24] concluded that the surface quality was primarily determined by brittle fractures, grooves, and pits on the processed material surface.…”

Crack extension is critical in determining surface forming process and machined surface quality of hard brittle materials. However, there is still a lack of research on this subject. In this work, the effect of crack extension on surface formation mechanism and surface morphology of silicon nitride ceramics was investigated via longitudinaltorsional composite ultrasonic-assisted mill-grinding, and reconstruction model of machined surface morphology considering crack extension was proposed. This model was quantitatively characterized and evaluated by the average roughness Sa and the kurtosis Sku. It is found that simulation results considering crack expansion were in good agreement with experimental results. Average relative errors in average roughness and kurtosis were found to be 7.95% and 9.46%, respectively. Primary effect analysis was performed to understand the influence of process parameters on machined surface morphology. It is found that ultrasonic vibration leads to changes in shear angle and shear velocity of abrasive grains, thereby changing machined surface morphology. Results presented here provide practical method for predicting and controlling machined surface quality during precision machining of ceramic materials.
