A currently common method to design high-performance workpieces is to combine two or more materials to one compound. This way, workpieces can be composed of the most qualified materials according to local loads.When machining high-performance workpiece compounds (e.g. cylinder crankcases), high quality requirements concerning the accuracy of dimension and shape as well as the surface roughness must be fulfilled. However, machining of workpiece compounds leads to unfavorable changes of the workpiece quality in comparison to machining of the single materials. Significant shape deviations occur w

An implant template with great precision is significantly critical for clinical application. Currently, the application of an immediate implant remains limited by the deviations between the planned and actual achieved positions and long periods required for preparation of implant templates. Material Extrusion (MEX), as one kind of 3D printing method, is well known for its low cost and easy operation. However, the accuracy of the implant template printed by MEX has not been fully researched. To investigate the accuracy and feasibility of in vitro computer-guided surgery assisted with a MEX prin

Abstract Material testing systems are crucial for evaluating the mechanical characteristics of materials. The material testing system’s accuracy determines the mechanical property of the material. Loading coaxiality is a crucial factor determining the precision of uniaxial tensile testing machines. Because of solid boundary nonlinearity in calculating loading coaxiality of the uniaxial test system, current methods can only be used for qualitative evaluation rather than quantification. Using the finite element method and the deep learning technique, a mapping relationship has been established b

MST or Muon Scattering Tomography is a major non-destructive technique to discriminate materials by finding deviation in muon tracks which depends on Z and density (ρ) of the medium the muon passes through. The scattering angle also depends on the incoming momentum of muon which is a key to distinguish multiple small deviations through large path-lengths of low-Z material from significant deviations through smaller path lengths of a high-Z target. An analytical function, derived by fitting the muon momentum distribution in a selected range has been used to predict the momentum of individual ev

This paper work want to underline the fact that even in down scale there are problems regarding deviation from the required dimensions. One of the problems is scaling effects, which occur in tribological aspects such as the friction coefficient, which increases with decreasing specimen size. Simulations investigations into mini forming process were carried out and mini conical parts have been obtained with different geometries. . The main

Chemical mechanical planarization is a process of achieving planar surfaces in the semiconductor manufacturing industry. The planarization of a surface is achieved by material removal from the wafer surface. The material removal depends on material properties and the process input parameters. Several studies have investigated the role of slurry chemistry to achieve a certain material removal selectivity of different materials on a patterned wafer. Here we propose a methodology of achieving planar patterned surface of Cu/Mn/MnN system using a model-based optimization for mechanical process para

In construction procurement in Indonesia there are still deviations in the tender process. The deviation is caused by an opportunity during the construction bidding process. The service providers are mutually looking for opportunities to seek personal or group benefits or from the working group that makes these deviations.

In the period of technological preparation and initial stages of development in the mass production of composite products, there is a fairly large number and variety of technological defects. The rate of these defects often exceeds the permissible requirements of design documentation and therefore results in faulty products. The most characteristic technological defect for composite structures reinforced with continuous fibres or fabric materials is the deviation of the thickness of the moulded composite from its projective value. Another type of common defects is local violations of integrity

As an accredited laboratory since 1998, a comprehensive quality control programme has been applied to assure the long-time reliability of results of human milk samples received

There is almost no facade without glass, glass as transparent material brings light and energy in buildings. Glass is known as brittle material, in case of failure – which occurs suddenly without warning – it shows no residual strength. Using the right glass products and appropriate design principles, robust and redundant facades can be constructed. Special attention is needed for details of structural design: small deviation in support conditions can have critical effects and penetrating water has a high potential of internal damage – often effecting energy performance and lifespan o

Abstract. Material Extrusion (MEX) technology for continuous fiber reinforced thermoplastic composites (CFRTCs) is based on the extrusion of a continuous fiber to create three-dimensional composite objects layer by layer. This technology explores three distinct methods: pre-impregnated filament, dual-nozzle, and coextrusion. The goal of this paper is to compare two printers, one using the dual nozzle technology and another relying on coextrusion. The first printer, Mark Two of Markforged, is based on dual-nozzle technology. The second printer, the Anisoprint Composer A4, stands out for its coe

Abstract A study to investigate the probabilistic variation in material failure mechanics of a typical high hardness armor (HHA) impacted by a tungsten penetrator was conducted. The HULL package was patched for simulation studies. Results from two different sets of calculations, each with a different randomness level, showed a relationship between the final penetrator lengths (between stations) and the prescribed randomness. Since higher percent deviation is likely associated with the higher failure rate of the target material, thus, at lower percent deviations, there is less penetration into

Abstract In Material Jetting, build material is deposited as single droplets onto a platform. This offers potential advantages such as faster processing and cheaper raw material compared to powder based processes. For metals, this technology is subject of several research projects. Due to variations in droplet size, the process inevitably results in deviations between the desired and the actual height of a printed layer. Such deviations can add up over several layers and thus lead to an unacceptably high overall geometrical deviation of the component. One possible solution to this problem is t

Abstract The 2014 modification of the EPRG Tier 2 guidelines for the assessment of girth weld defects includes a modified criterion for weld strength overmatching. First experiences have shown it to be highly restrictive and to potentially limit the use of manual girth welding techniques. Recognizing this, EPRG launched a project to develop a sound justification to a potential new modification of the EPRG weld strength criteria, supported by a database of mechanical weld characteristics provided by EPRG members and a probabilistic analysis. This paper summarizes the findings of the project. Th

Abstract Additive Manufacturing (AM) processes generate parts layer-by-layer without using formative tools. The resulting advantages highlight the capability of AM to become an inherent part of product development. However, process-specific challenges such as high surface roughness, the stair-stepping effect, or dimensional deviations inhibit the establishment of AM at the industrial scale. Thus, AM parts often need to be post-processed using established manufacturing processes. Many process parameters and geometrical factors influence the dimensional accuracy in AM.
