Carbon/Carbon (C/C)-SiC composite materials attained much attention due to its unique properties like immense thermal conductivity, high corrosion, and abrasive resistance. Few scholars have systematically studied the grinding machinability of 3D C/C-SiC composite material. In this paper, the grinding experiment of 3D C/C-SiC composite material was carried out with a resin-bonded diamond grinding wheel. The effect of machining conditions on the grinding force, micromorphology, surface quality, and residual stress was studied, and the material removal mechanism was analyzed in-depth aimed at the three typical fiber orientations. The result shows that the surface roughness of different fiber areas follows the order: 90° fiber > 0° fiber > Normal fiber. The fiber's orientation showed a significant effect on the mechanism of material removal. The residual thermal stress of C/C-SiC composite material increases from 32.25 to 207.43 MPa during the grinding process. Polishing the ground surface not only can remove the crack layer and residual stress layer but also can introduce residual compressive stress layer, which can effectively enhance the material strength.

“…It is found that both cutting speed and direction of fiber cutting significantly affect the surface topography in RUM of C/Sic composites. The relatively low amount of spindle speed and high amount of ultrasonic amplitude apparently plays an important role in further improvement of hole surface quality [23].…”

Ultrasonic machining (USM) is a process used for machining material with high hardness and brittle nature that are difficult to machine. The USM has an upper hand on the other non-conventional process like electron discharge and laser beam machining which have thermal effect on workpiece. Workpiece chracteristics are also not limited by chemical and electrical properties. This paper discusses about the rotary ultrasonic drilling (RUD) machining process which is a variant of USM and the recent developments that it gone under through the RUD. This paper also reviews about the various methodology adopted by researchers to achieve optimum output parameters like Material Removal Rate, Surface roughness, Edge chipping etc. by altering the process characteristics like spindle speed, feed rate, ultrasonic power etc. as well as machine characteristics like tool type, support length etc. The paper also deals with the material used with the RUD worldwide and the findings of researchers on them.

“…fracture morphology, residual stresses…) of the hole walls is considered a more compelling and challenging factor that needs further characterisation and study. Due to the orthotropic nature of long-fibre reinforced CMCs and the rotation direction of a drill bit, different fibre orientations are found during the cutting process, significantly affecting the machined surface [27], [38]. Wang et al [38] studied the influence of the process (RUM against conventional drilling) with no obvious evidence that the later improved the surface finish.…”

Ceramic Matrix Composites (CMCs) are currently an increasing material choice for several high value and safety-critical components, fact that has recently originated the need of understanding the effect of several machining processes. Due to the complex nature of CMCs -i.e. heterogeneous structure, anisotropic thermal and mechanical behaviour and generally the hard nature of at least one of the constituents (e.g. fibre or matrix)machining become extremely challenging as the process can yield high mechanical and thermal loads. Furthermore, the orthotropic, brittle and heterogeneous nature of CMCs result in different material removal mechanisms which lead to unique surface defects. Hence, this review paper attempts to provide an informative literature survey of the research done in the field of conventional and non-conventional machining of CMCs with a main focus on critically evaluate how different machining techniques affect the machined surfaces. This is achieved by exploring and recollecting the different material characterisation techniques currently used to observe and quantify the mechanical and thermal surface and subsurface damages and highlight their governing removal mechanisms.
