“…To reaffirm the formation of an oxide layer when machining SiC-based CMCs and obtain further information, a quantitative analysis was performed by measuring the atomic percentage of elements via X-Ray Photoelectron Spectroscopy (XPS). As shown in Figure 21, the results clearly demonstrated an increase of the oxygen content in the machined surface when rising the laser power [62]. showing a the XPS quantitative analysis for different processing powers [62].…”

“…Laser machining is a viable process to CMCs, especially for the hole-making in ultra-hard SiC-based CMCs as the conventional drilling of small holes can become challenging [62] due to the hard and heterogeneous nature of the CMCs. Moreover, compared to other glasses or ceramics, SiC species have shown to absorb the laser wavelength effectively, establishing the laser as a relatively efficient machining technique [63].…”

“…When decreasing the pulse duration, the influence of the debris-removal mechanism becomes more important, especially for long aspect ratio holes. This phenomena was studied for a picosecond laser ablation in C/SiC and SiC/SiC [62], [65] reporting that, when using low energy densities (e.g. 0.51 J/mm 2 ) the debris tended to not be removed, leaving an irregular surface finish and being unable to produce through-holes (Figure 19a).…”

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.

“…However, due to the existence of hard ceramic matrix, CMCs are regarded as typical difficult-to-machine materials. In order to improve the machining of CMCs, various conventional and unconventional processing methods have been introduced, such as grinding [2], laser beam machining [3], rotary ultrasonic machining [4]. Rotary ultrasonic machining has been sufficiently proved to be suitable for the hole manufacturing of CMCs, with dramatically reduced cutting force and improved hole exit quality [4].…”

Abstract. The feasibility of rotary ultrasonic face milling (RUFM) of ceramic matrix composites was evaluated experimentally in this study. Preliminary experimental results show that, comparing with conventional grinding (CG), RUFM can reduce cutting forces dramatically though with a little enlargement of surface roughness. Both in CG and RUFM, a positive dependency of surface roughness on cutting force can be deduced. For machining of 2D-C/SiC composites, the fiber direction significantly affects the cutting force and surface roughness. When fibers are parallel to the cutting plane, the cutting force and surface roughness are much larger than that when fibers are perpendicular to the cutting plane.

Extensive R&D applied various laser sources — from nanosecond VIS‐wavelength to femtosecond IR and water‐jet guided lasers — to enhance the quality and efficiency of laser structuring, fine cutting, and drilling of silicon carbide. Tests focused on surface roughness, cutting line precision, and high ablation rates. Challenges due to diverse material compositions, like diamond layers, required combined methods to develop viable approaches. To meet economic constraints, mechanical grinding was integrated with recurring laser processing.
