Summary: This paper investigates the formation mechanism of adhered debris on the surface of turned titanium alloy. The adhesion rate of debris is calculated and evaluated using image extraction technology. The effects of cutting parameters and cooling conditions on the debris adhesion rate are also examined. Furthermore, a finite element simulation and a thermal camera are utilized to analyze the chip temperature and trajectory during the turning process. The results reveal that adhered debris mainly comes from the adhesion of the built-up edge, micro-chips formed during cutting, and micro-chips generated by friction between the chip and the machined surface. Additionally, cutting speed is found to be one of the most significant factors affecting debris adhesion, with the adhesion rate decreasing significantly as cutting speed decreases. The study also demonstrates that coolant can effectively reduce debris adhesion, with a more pronounced effect at low feed rates.

Summary: This study investigated the feasibility of using L-PBF to fabricate two Ti-6Al-4V-based bimetals, Ti-6Al-4V/γ-TiAl and Ti-6Al-4V/Ti-6242, which may have great potential for the future manufacturing of aerospace components. The bimetal Ti-6Al-4V/γ-TiAl was unsuccessfully built due to the intrinsic cold cracking of γ-TiAl processed by L-PBF. In comparison, the bimetal Ti-6Al-4V/Ti-6242 was successfully manufactured by L-PBF with a solid and defect-free interface.

Summary: This study examined the dry machining of Titanium alloy Grade 5 (Ti-6Al-4V) with cryogenic treated cutting inserts. The results showed that cutting speed is the most influential parameter on the machining characteristics. Increasing the cutting speed and feed rate can reduce surface roughness and flank wear rate. Deep cryogenic treatment improves the hardness, wear resistance, and toughness of the inserts. Lower cutting speeds and feed rates result in less rake surface wear.

Summary: Additive manufacturing (AM) is becoming more widespread in various industries, and this study investigates the mechanical and microstructural properties of metal parts fabricated through AM, particularly focusing on Inconel 718 specimens fabricated by selective laser melting (SLM) with different heat treatment temperatures. The research findings demonstrate that heat treatment temperature can alter the microstructural aspects of the specimens and significantly enhance the microhardness and wear resistance due to the final state of microstructure. Furthermore, a comparative study shows that Inconel 718 specimens fabricated by SLM can exhibit much higher wear resistance than conventionally produced Inconel 718 if heat-treated at specific temperatures.

Summary: In the study, it was found that cryogenic and CryoMQL machining for turning PMMCs result in higher cutting force and energy consumption compared to MQL technique. However, CryoMQL technique shows better surface roughness values than MQL and cryogenic machining. Moreover, all three cooling and lubrication techniques produce powder type chips with higher C(in) values.
