Abstract The applications of hard and brittle materials, typically represented by advanced ceramics, for a number of high-performance components have recently generated high interest. To meet this increasing demand, high efficiency machining technologies are needed. Jan 01, 2022Numerous non-traditional machining techniques are used to machine such hard and brittle materials. Different machining processes play a significant role in various aspects such as biomedical, manufacturing, aerospace, marine, automobile etc. [1], [2], [3], [4]. Babbar et al. [5] investigated the magnetic abrasive machining process on a brass plate. At present, ultra-precision grinding is usually used for the efficient machining of hard and brittle materials. The height of residual material on the grinding surface is the key factor affecting the quality of the ultra-precision machined surface. Precision Grinding of Hard and Brittle Materials Jan 01, 19876. Concluding Remarks on the Hiqh-Efficiency Grindinq of Hard and Brittle Materials The grinding process of hard and brittle materials is primarily due to the micro-brittle fracture of the material. The grinding force and power can be, therefore, considerably reduced by taking advantage of this phenomenon. Precision Grinding of Hard and Brittle Materials . Two novel techniques were used to study the formation of ductile mode streaks during diamond grinding (primary process) of germanium, silicon, and glass that aid the secondary process of polishing. Ductile streaks produced during diamond grinding of hard and brittle materials have aided the subsequent process of polishing. Two novel techniques were used to study the formation of ductile mode streaks during diamond grinding (primary process) of germanium, silicon, and glass. In the first technique, aspheric surfaces were generated on Ge and Si at conventional Abstract Microstructured surfaces on hard and brittle materials are widely used in a series of scientific and industrial applications, such as micro-electro-mechanical systems, nano-electro-mechanical systems, electronic devices, and medical products. However, the efficient precision machining of microstructured surfaces on hard and brittle materials faces great challenges.
