The quality standard SR EN 1090:2012 requirements enforce a maximum consistency both on the metallic construction manufacturing process and during all the additional stages till the construction site becomes a final product ready to be used. Any lack of attention during this complex manufacturing process might drive to different classes of damage consequences due to minor or major nonconformities. Therefore, among other important procedures, I refer here to the importance of marking both the raw materials (as part of the final product) and leftovers (as part of future work) resulted from the cutting process. I propose in this paper a specific database and a simple marking procedure based on QR codes. The database consists of detailed descriptions of all kind of metallic materials with different shape, structure and quality as well as all important information extracted from the quality certificate 3.1. that accompanies the goods once they arrive into the manufacturer’s storage. Since the standard underlines the necessity to identify any material during work processing, the system allows conversion of large text with important data into a QR code that can be scanned and therefore the material quickly identified into the manufacturer’s workshop.

In recent automobile trends, the functions of opening and closing the vehicle door are accomplished by touch sensor and smart-phone NFC (Near Field Communication) systems. These convenience features are incorporated into the outdoor handle. However, this function can’t be used when chrome plating is applied to this part for design purposes. To solve the problem of chrome plating, we studied a metal sputtering deposition process technology, which can preserve the metal feeling without interfering with NFC and touch sensor operation. To achieve this interface communication and sensing performance, we developed a surface treatment that can generate micro-cracks in the thin film layer. We also investigated how the door handle manufacturing process affected the shape of the micro-cracks in the thin film. Results showed that the thickness of the thin film and the target power played a crucial role in controlling the residual tensile stress in the thin film, which was one of major factors responsible for generating micro-cracks in the thin film layer. The shape of the micro-cracks in the thin film was affected by the adjacent layers of the thin film, the primer paint and UV top coat. The surface energy of the primer paint and the shear stress produced by the hardening of the UV top coat were found to affect the shape of the micro-cracks. In addition, we found that there was no change in the shape of the micro-cracks with additional heat treatment, if the residual tensile stress was sufficiently relieved by the micro-cracks formed in the thin film. The slits between the micro-cracks in the outdoor handle cover allowed the Capacitance Sensor and NFC to perform.

Abstract The work deals with technology Patternless process that combines 3 manufacturing process mold by using rapid prototyping technology, conventional sand formation and 3D milling. It's unconventional technology that has been developed to produce large-sized and heavyduty castings weighing up to several tons. It is used mainly in prototype and small batch production, because eliminating production of models. The work deals with the production of blocks for making molds of gypsum and gypsum drying process technology Thermomold. Into blocks, where were made cavities by milling were casted test castings from AlSi10MgMn alloy by gravity casting. At machining of the mold cavity was varied feed rate of tool of cemented carbide. Evaluated was the surface roughness of test castings, that was to 5 micrometers with feed from 900 to 1300 mm/min. The dimensional accuracy of castings was high at feed rate of 1000 and 1500 mm/min did not exceed 0.025 mm.

High Flexibility

AbstractHolograms have found their use as optical elements in a variety of applications. Yet using them with incoherent and divergent lightsources like LEDs proves difficult, as their characteristics need to be simulated by lasers during manufacturing to get a correct reconstruction of the desired light distribution. We present a new setup to allow for a high flexibility during the manufacturing process, which is able to produce volume holographic cell arrays (VCAs) that can be illuminated directly with uncollimated LEDs. Results are presented for the case of reflection holograms.
