TL;DR: In this article, a rotary ultrasonic burnishing of titanium alloy Ti-6Al-4V, whose surface had been machined with the face milling process, was proposed.
Abstract: Ultrasonic burnishing is usually applied to make machined surface modification. The acoustic softening effect caused by ultrasonic vibration is beneficial to the machining of difficult-to-cut materials. In the present work, a burnishing force prediction model was proposed for rotary ultrasonic burnishing of titanium alloy Ti–6Al–4V, whose surface had been machined with the face milling process. Firstly, the contact between the burnishing roller and one single milling mark was analyzed with plane strain assumption based on the Boussinesq–Flamant contact problem. Then, the effect of ultrasonic softening on the yield stress of Ti–6Al–4V was investigated. The critical contact width and contact load that the burnishing roller crushed on one single milling mark were examined to confirm the feasibility of the proposed ultrasonic burnishing force prediction model. The experimental verifications were carried out at various ultrasonic powers. The burnishing forces from experiment measurements were consistent with the calculated results from the proposed model. The mean deviations between theoretical and experimental results of the ultrasonic burnishing force were 10.4%, 12.2%, and 15.2%, corresponding to the ultrasonic power at the level of 41 W, 158 W, and 354 W, respectively.

TL;DR: The aim of this work is to optimize the roller burnishing process parameters for minimizing the surface roughness using response surface methodology (RSM) and lion optimization algorithm.
Abstract: The aim of this work is to optimize the roller burnishing process parameters for minimizing the surface roughness using response surface methodology(RSM) and lion optimization algorithm. A RSM based box-behnken design is utilized for experimentations. The empirical model of surface roughness is developed for showing the relation between inputs and output of the burnishing process. The analysis of variance (ANOVA) method was used to check the accuracy of the developed mathematical model. With the developed mathematical model, the roller burnishing process parameters were then optimized to minimize the surface roughness by a new type of lion optimization algorithm. Further, validation test has been conducted for the optimal conditions suggested by lion optimization algorithm. The experimental value agreed with those predicted value with 3.225 of relative error percentage.

TL;DR: In this article, the effect of surface roughness and surface hardness during burnishing of Al(SiC)p workpiece material was studied using WC rollers with PVD coating and its effects were studied.
Abstract: Roller burnishing involves plastic deformation by pressing a hard roller against the workpiece. The number of passes, rotational speed of the workpiece and type of lubricant were taken as input parameters. Its effect on surface roughness and surface hardness during burnishing of Al(SiC)p workpiece material was studied. Titanium aluminium nitride (TiAlN) coating was given to the WC rollers with PVD coating and its effects were studied. Roller burnishing of Al(SiC)p MMC can reduce the surface roughness up to 78.84 % and increase surface hardness up to143.4 %. Based on the extrapolated results it is noted that coated rollers under dry conditions produce low surface finish and high hardness.

TL;DR: In this article, a simple internal roller burnishing tool is used to perform the cold working process on the holes drilled in EN8 material by varying the spindle speeds of the drilling machine.
Abstract: Burnishing is a cold working, a surface treatment process in which plastic deformation of surface irregularities occurs by exerting pressure through a very hard and smooth roller on a surface to generate a uniform and work-hardened surface. In this work, a simple internal roller burnishing tool is used to perform roller burnishing process on the holes drilled in EN8 material by varying the spindle speeds of drilling machine. The speed which produces maximum smoothness or minimum roughness on the surface is considered to be an optimal speed for carrying out burnishing operation in the drilled holes.

TL;DR: In this paper, the authors show that using the right ductile iron material and optimized roller burnishing conditions can raise the fatigue limit of cast crankshafts to values even higher than forged steel ones (material 38MnVS6).
Abstract: A lot of innovations in molding and casting technology and also simulation techniques have made ductile iron more and more competitive and it even competes meanwhile against steel forgings. A successful substitution of steel forgings for example is the wheel carrier for a high volume car with the Georg Fischer new ductile iron material 'SiboDur', a ductile iron family with high strength and high elongation at the same time. But there is still a great potential for ductile iron castings to substitute steel forgings, in particular in the automotive industry. One example is the crankshaft for the engine: Quite a lot of gasoline engines are equipped with ductile iron crankshafts, but for instance most of the diesel engines are still running with forged steel cranks. The reason is mostly the belief of design engineers that it is not possible to get similar fatigue limit with castings com-pared to forged steel. This belief may often be correct, but using local strengthening technologies, such as roller burnishing of bearing fillets or inductive hardening of highly stressed areas can raise the fatigue limit of casted crankshafts dramatically. The paper presents studies which show that using the right ductile iron material and optimized roller burnishing conditions can raise the fatigue limit of cast crankshafts to values even higher than forged steel ones (material 38MnVS6). But even quenched and tempered forged steel crankshafts are in the focus to be substituted by castings. It is well known that ductile iron also can be induction hardened, but the induction hardening of ductile iron is still an empirical technology. This leads to the second part of the paper: In a cooperation of Georg Fischer and RWP a research project was carried out to develop a simulation technology to predict the residual stresses in a cast crankshaft due to induction hardening under different condi-tions. The results are very encouraging and enable us today to predetermine the induction hardening conditions to get optimized fatigue behavior of ductile iron crankshafts. Of course, the findings can also be used for other applications than crankshafts.
