Experimental and model-based investigation of cutting mechanisms when ultrasonic-assisted machining SiCf/SiCm ceramic matrix composites

Year: 2025

Type: article

Abstract: Ceramic matrix composites (CMCs) offer superior properties, such as an excellent high-temperature strength, outstanding corrosion resistance and low density. Therefore, CMCs are currently the preferred material for hot section, safety-critical and braking components in the aerospace, energy and automotive industries. However, CMCs due to their high hardness and strong anisotropy are difficult to cut with conventional machining. This research study attempts to improve the machinability of CMC material by combining the advantages of ultrasonic-assisted cutting and the high performance polycrystalline diamond. For this purpose, experimental and simulative investigations are performed to characterize and to describe the cutting mechanisms when machining CMCs.
