Summary: This research investigates the influence of part geometry and machining conditions on tool vibration and surface integrity in H13 hard turning. The results indicate that tool vibration is mainly affected by the feed rate, while surface integrity is mainly influenced by the part geometry. This study provides valuable guidance for process planning involving the machining of hardened steels.

Summary: The effect of slide diamond burnishing on surface roughness, residual stresses, and microhardness of 42CrMo4 hard-turned steel was studied. It was found that the effect of one parameter was highly affected by the others. As a result, the optimal burnishing parameters were specified, with which better surface quality was obtained than after grinding.

Summary: This paper investigates the topographical behavior of precipitation hardened magnesium alloy AZ80A subjected to cavitation peening. The introduction of surface residual compressive stress is the main feature of this new method, which differs from traditional mechanical processing methods and plays a key role in improving the surface performance of the metal material. After heat treatment, cavitation peening raises the surface hardness and increases the compressive residual stresses of the magnesium alloy specimens. However, it also results in increased surface roughness.

Summary: This study investigates the effects of different machining parameters on the surface integrity of the nickel-based alloy Inconel 718 during face-turning experiments. The results show that a smoother, more uniform surface is obtained when using a ceramic insert. The residual stress and microhardness distributions induced by the carbide and ceramic inserts are similar.

Summary: High surface integrity is crucial for hard turned parts. Preheating and softening the hardened EN31 steel using a Yb-fiber laser improves machinability and reduces tensile residual stress. Thermal simulations determine the temperature profile of the preheated workpiece for laser-assisted hard turning (LAHT). LAHT results in a more compressive residual stress profile, lower cutting forces, and better surface finish compared to conventional hard turning.

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: The study investigates the effect of different turning parameters on surface residual stress and roughness of titanium alloy parts using the response surface method. A mathematical model is established through multiple linear regression to analyze the relationship between surface integrity parameters and fatigue life. The results indicate that feed rate, depth of cut, and cutting speed have different impacts on surface residual stress and roughness, while residual compressive stress and surface roughness significantly affect the fatigue life.

Summary: This study investigated the influence of face milling parameters and tool grade on the surface integrity of annealed AISI H13 steel. The results showed that depth of cut and feed per tooth were the main factors affecting milling force components. Cutting speed and tool grade had no effect. Depth of cut significantly affected the machined surface temperature, while feed per tooth had the greatest influence on surface roughness. The use of a cutting fluid improved surface quality and milling with cermet resulted in better surface roughness compared to tungsten carbide.

Summary: This study investigates the effects of cutting tool wear on the machined surface integrity characteristics during milling of Inconel 718. It was found that cutting forces increase with greater tool flank wear width, while the highest cutting temperature decreases at a flank wear width of 0.3 mm.

Summary: Surface integrity is crucial for the fatigue performance of components. This study investigates the effects of cutting parameters on surface integrity characteristics through ball end milling of TC17 alloy. The experimental results reveal that increasing the cutting parameters leads to higher surface roughness, surface compressive residual stress, and milled surface microhardness. Empirical models are developed to predict the surface integrity characteristics, which are of great significance in optimizing cutting parameters.

Summary: The aim of this research was to investigate the effects of different cooling conditions on machinability as potential alternatives to traditional cooling methods. A series of experiments were performed to test dry machining, minimum quantity lubrication (MQL), nanofluids, cryogenic cooling, and hybrid cooling methods. The results showed that under specific nanofluids conditions, hBN (0.2%) + graphene (0.2%) performed well, and overall cryo+nano MQL produced the best results in terms of tool wear, microhardness, surface, and chip morphology. The cooling effect of the Cryo-MQL regime, which maintains the cutting temperature at a tolerable level and preserves the lubricant performance of the MQL, was identified as the cause of the lowest Vb value of 90 μm.
