This paper discusses a practical example of machining crank shafts, which are the central part of compressors made in mass production, in order to point out the importance of selecting proper machining parameters and presenting their further relation to product quality. As the shaft’s dimensions varied significantly after machining in comparison to the prescribed one, an analysis of the relatio...

GH4169, a nickel-base heat-resistant alloy, usually has outstanding high-temperature strength, excellent thermal stability and good wear resistance. However, it is hard to cut and its machined surface quality and integrity are particularly sensitive to a manufacturing process employed. The study reported in this paper was conducted to initially, review existing research on machining-induced sur...

PURPOSE MR-only treatment planning requires images of high geometric fidelity, particularly for large fields of view (FOV). However, the availability of large FOV distortion phantoms with analysis software is currently limited. This work sought to optimize a modular distortion phantom to accommodate multiple bore configurations and implement distortion characterization in a widely implementable...

Duplex stainless steels come under the difficult-to-machine category, considering loss of sensitive balance between constituent phases due to thermal and mechanical working effects. Selective laser melting is emerging as an additive process for achieving near-net shape manufacturing solutions with these steels. Nevertheless, post-printing machining essential varying degrees machinability respon...

Armor steels have good strength and corrosion resistance; however, due to their difficult machinability, high power consumption occurs. High increases the cost in machinability studies. Therefore, minimizing is important for sustainable cleaner production. In order minimize during machining, factors such as workpiece material, cutting tool material geometry, machining conditions parameters must...

aluminium matrix composites (amcs) materials are continuously displacing traditional engineering materials because of their advantages of high stiffness and strength over homogeneous material formulations. properties of amcs can be tailored to the demands of different industrial applications by suitable combinations of matrix, reinforcement and processing route. presently, several grades of amc...

This study describes the influence of the steel characteristics of Ca-treated carburising steel grades during hard part turning of synchronising rings in gearbox production. The main focus was on the chemical composition of the non-metallic inclusions in the evaluated workpieces and their effect on the PCBN tool wear. In addition, a Ca-treated carburising steel grade was compared to a standard ...
