TL;DR: In this article, the authors consolidate the servitization knowledge base from an organizational change perspective, identifying developed, developing and undeveloped topics to provide a platform that directs future research.

TL;DR: In this paper, the effect of the abrasive water jet process parameters on the quality of cut (taper and surface roughness) was carried out, and the machinability index for various composite materials with different thicknesses was found experimentally, which showed very different results for different materials.

TL;DR: In this paper, a design of experiments approach was taken, considering variables such as water pressure, nozzle stand-off distance, traverse speed, nozzle orifice diameter, abrasive mass flow rate and tool-path step over distance.

Abstract: The urge in aeronautics to reduce cost and time to flight of components without compromising safety and performance stimulates the investigation of novel manufacturing routes. Shaped Metal Deposition (SMD) is an innovative time-compression technology, which creates near-net shaped components layer by layer by weld deposition. Especially for Ti alloys, which are difficult to shape by traditional methods such as forging, machining and casting and for which the loss of material during the shaping process is also very expensive, SMD promises great advantages. Applying preliminary SMD parameter, four different tubular components with a square cross section and wall thicknesses of about 9 mm were built. The microstructure of the Ti-6Al-4V components consists of large prior β grains, elongated along the temperature gradient during welding, which transform into a lamellar α/β substructure at room temperature. The ultimate tensile strength was between 880 and 1054 MPa. The strain at failure was between 3.0 and 11.3 % for tensile testing parallel to the deposition plane and between 9.1 and 16.4 % perpendicular to the deposition plane. The micro-hardness (3.1 - 3.4 GPa), the Young's modulus (117 - 121 GPa) and the oxygen and nitrogen content are comparable to cast Ti-6Al-4V material.

TL;DR: In this paper, a systematic analysis of nearly 90 selected publications was conducted to explore how gamification can aid the transformation process of manufacturing organizations into advanced service providers, arguing that such mechanics can facilitate and strengthen companies' transformation into advanced-service providers.
