Summary: DC 53 steel, as a potential substitute for AISI D2 steel, shows competitive hardness and improved toughness. Turning experiments were conducted on DC 53 steel using Xcel modified inserts. The results indicate that the hardness of DC 53 steel primarily affects tool life, surface roughness, volume of material removed, and machining zone temperature. Crater wear and wear mechanisms were observed, and the optimal feed rate threshold for excellent performance was found to be less than 0.20 mm/rev.

Summary: The Al2O3-WC-TiC-graphene composite ceramic tool fabricated by two-step hot pressing shows superior cutting performance and good anti-friction and wear resistance properties. The contributions of graphene to the mechanical properties, lubricating properties and thermal conductivity of the tool are responsible for its enhanced cutting performance.

Summary: This article discusses the wear of CNMG-coated sintered carbide cutting inserts by different manufacturers when turning hardened steel. The study focuses on the wear course and its connection to chip production. The quality of the coating layers was found to significantly influence the wear rate of the inserts. The evaluation of cutting tool wear and chip production has economic potential for minimizing costs in manufacturing companies.

Summary: Hardened and tempered ultrahigh strength steels are new generation materials with strengths exceeding 2100 MPa and reasonable ductility. The study shows that by applying specific hardening and tempering processes, different combinations of strength and ductility can be achieved. The strengthening mechanism of these steels includes a lath martensite matrix, dispersion of epsilon-carbide and (V, Ti)(4)C-3 precipitation, and finer grains obtained through alloying and residual carbides.

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: Research shows that subcooled MQL can enhance the cooling effect of metal cutting. The simulations are in good agreement with experiments, indicating that there is only a small difference between subcooled MQL and regular MQL in terms of wear behavior, cutting forces, and process temperatures. However, substantial residual plastic strain on the workpiece surface after machining suggests significant implications for inverse material modeling.

Summary: This study investigates the effect of cryogenic cooling with liquid nitrogen and liquid carbon dioxide on the machining of hardened AISI 4340 steel. The results show that cryogenic cooling can lower the cutting temperature, improve surface roughness, and reduce flank wear. In particular, the machining zone with cryogenic liquid nitrogen exhibits the highest microhardness value.

Summary: The tribological behavior of quench-tempered ductile iron (QTDI) and austempered ductile iron (ADI) with similar hardness was investigated. QTDI was composed of cementite particles, ferrite and spheroidal graphite, whilst ADI was consisted of acicular ferrite, retained austenite and spheroidal graphite. Wear tests indicated that QTDI exhibited a lower friction coefficient than ADI. However, ADI had a better wear resistance than QTDI, which was because the transformation of re-sidual austenite into martensite induced by friction stress resulted in the increase of surface hardness. Worn surface morphology indicated that the main wear mechanisms of QTDI was adhesive and abrasive wear. How-ever, the surface fatigue wear was observed for ADI.

Summary: The study proposes the use of a Magnetorheological (MR) fluid damper to suppress tool vibration in hard tuning. The damper can be easily installed without structural modification and regulates variable cutting conditions by changing its damping coefficient with the magnetic field. Comparison between in-house prepared MR fluid and commercial MR fluid shows their equal performance. The MR damper effectively reduces high-amplitude vibration and improves surface roughness and tool wear.

Summary: This study evaluated the surface integrity and flank wear of uncoated cermet inserts in dry turning of AISI 1045 steel. Cutting speed and feed were varied and their effects on surface quality were analyzed. It was found that feed had a greater influence on the turned surface quality than cutting speed. The surface was significantly damaged with the progression of insert flank wear. Abrasive wear was the predominant wear mechanism observed in the experiments.
