Summary: Metal matrix composites (MMCs) have attracted interest for their lightweight and improved mechanical properties compared to non-reinforced metallic alloys. However, machining MMCs poses challenges due to their heterogeneous structure, which can reduce cutting tool life and deteriorate part surface integrity. This study proposes ultrasonic vibration-assisted turning (UVAT) as an efficient approach to machine MMCs and investigates its effects on tool wear mechanisms, surface finish, and chip morphology. Experimental results show that the adoption of ultrasonic vibrations with high feed can significantly increase tool life, making UVAT a suitable approach for efficient machining of MMCs.

Summary: This paper investigates the effects of cutting performance and tool wear on the machining of SiCf/SiC ceramic matrix composites. The experimental results show that the PDC tool achieves the best cutting performance and is more suitable for machining silicon carbide fiber-reinforced silicon carbide matrix composites. Additionally, it is found that the tool wear decreases first and then increases with increasing ultrasonic amplitude, reaching a minimum at an amplitude of 3 μm. The main wear mechanism of the tool is abrasive wear, with the primary wear form being the spalling of polycrystalline diamond abrasive grains.

Summary: Vibration Assisted Turning (VAT) is a hybrid machining process that utilizes a tool vibrating at ultrasonic frequency to machine materials. VAT can reduce machining forces and tool wear, and studying chip formation and tool-chip interaction helps to understand and control the process performance. By analyzing chips formed at different vibration amplitudes, the study found correlations between chip characteristics, forces generated, and surface integrity. The numerical model showed that ultrasonic vibration reduced the contact pressure and frictional forces at the chip-tool interface.
