“…Positive and sharp geometry is preferred to avoid built-up edge (BUE) formation, with a ground insert generally providing superior tool life, particularly when finish turning [90]. Increasing the cutting edge radii [26] or incorporating a short ($0.06 mm) negative K-land [123] was shown to improve tool life when end milling and ball nose end milling Ti-6Al-4V, respectively.…”

“…Two categories of tool materials are used: (i) hard materials (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30): cemented carbides, coated carbides and ceramics; (ii) superhard materials (50-85 GPa); cubic boron nitride (CBN), CVD diamond and polycrystalline diamond (PCD) [199,212]. While carbide tools possess the highest transverse rupture strength and fracture toughness, diamond tools have the highest hardness and thermal conductivity.…”

The extensive tribological use of nodular cast iron in ground transport industry, e.g., trains and automobiles, has brought growing scientific interest. The various applications of this material are due to the versatility of mechanical properties without adding alloy elements, making possible to achieve good results varying just the heat treatment. Due to its high fluidity, workpieces made of this material can be produced with final dimensions and shapes very close to the designed ones, making necessary just the use of finishing machining operations to get the final dimensions, more specifically those concerning the grinding process. To optimize cost production, machining processes became the focus of scientists and engineers. The grinding wheel can determine the success of an operation as its properties influence productivity and workpiece quality decisively. This work analyzes the grinding process of the ductile iron GGG-70 (average hardness of 270 HB) using two types of vitrified bonded CBN grinding wheels, which have as their only distinction the marked difference in friability of the abrasive grains. The performance of each grinding wheel will be analyzed taking into account the output parameters values obtained from surface roughness, average power, diametric wear of the grinding wheel, microstructure of the ground surfaces, and microhardness measures from the ground surface to the center of the workpiece. It was observed that the less friable wheel produced, regarding the average surface roughness, values of 0.27, 0.30, and 0.36 μm for the feed rates of 0.5, 1.0, and 1.5 mm/min, respectively, and, regarding the diametric wheel wear, produced values of 2.52, 2.99, and 4.01 μm for the same feed rates, respectively. On the other hand, when using the more friable wheel, average surface roughness values of 0.33, 0.44, and 0.64 μm and diametric wheel wear values of 3.21, 4.22, and 7.24 μm were obtained. In this way, the less friable wheel showed better results for all the conditions. Considering the feed rate order of 0.5, 1.0, and 1.5 mm/min, the improvement in surface roughness was about 18.18, 31.82, and 43.75%, respectively, and the reduction of the wheel wear was about 21.50, 29.15, and 44.61%.

“…[4] To the present day, different strategies for riblet methodology were pursued mainly by material scientists and engineers in order to solve problems with respect to riblets homogeneity and dimensions, as well as cost effectiveness. Commercial manufacturing methods that were investigated included rolling, [6] profile grinding with multiple profile, [7] where the minimal producible structure dimension is relatively large (h/s ! 0.62), [8] with the methods of EDM (Electric discharge machining), [9] ion implantation through masks.…”

Structuring surfaces with so-called riblets improve the drag reduction on surfaces of airplane wings or blades for aero-engines. Here the result of collaboration between four research groups which focused on the transferability of the riblet approach to high temperature material systems. With respect to the applications excellent mechanical properties and high temperature oxidation resistance of the riblets are necessary. Applicable processes via halogenation, coatings fabrication, and laser ablation plus oxidation to process small riblets on relevant material systems for aero engines (IN718, PWA1483, TNMB1) are presented. The riblets have different compositions such as metallic, half-and completely oxidized. The riblet morphology is characterized and studies of the mechanical stability outlined promising results. All tested riblets exhibit good bonding to the substrate. Results of quasi cyclic four point bending tests and low cycle fatigue are discussed taking into account the differences between the riblet and the substrate composition.
