Kutatói szeminárium 2021


Szerkesztőbizottságunk 2021-ben életre hívta a Műszaki és Informatikai Megoldások Kutatói Szemináriumot annak érdekében, hogy fiatal kutatók és doktoranduszok bemutathassák munkájukat, elért eredményeiket. Az előadásokat angol nyelven, online szervezzük, MS Teams felületen. Valamennyi prezentációt egy rövid vita követ, amely keretében bármely résztvevő megoszthatja véleményét, javító szándékú kritikáját annak érdekében, hogy segítse a fiatal kutatók további munkáját.

  The available machines in our laboratory are very commonly used in small and medium companies. This machines combined with a suitable MES system – the implementation is in progress - and with the necessary modifications are a modern I4.0 system. My research is focusing now to evaluate the CNC milling machine's implemented workpiece measurement system. This data is easily transferable for further efficiency, and M2M studies. In order to ensure the productivity and the predefined level of quality inspections the same dimension related measurements are execued with CMM. This data give us a complex picture about the machine and tool conditions.

  In this project we created an algorithm using Matlab that could detect the machining cycle (chip formation) from the vibration signal of a CNC machine. The created method fitted the optional result almost as good as the machining cycle detection by a human. The proposed method has worked reliable in the cases where the convenient visual detection were unusable. The only information the method requires is the spindle RPM to detect the cycles. The algorithm later tested on multiple feedrates where it proved that it is usable in those conditions as well.

  Recrystallization (RX) occurs in polycrystalline materials during thermo-mechanical processing. The crystallographic textures evolved in Aluminium alloys usually account for a strong anisotropy of mechanical properties. Which is the main disadvantage of using light metals like Al alloys in light-weight applications. The goal of this research is to overview the above-mentioned drawbacks. The goal can be reached by a detailed investigation of texture evolution during RX supported by recrystallization kinetics. In this piece of work, it is intended to represent the kinetics of recrystallization via the driving force of RX that is supported by dislocation density in the material.

  Investigating of the Hp's scanner resolution, reducing the scanning picture's noise with the optimalization of the settings. After the scanning process, following the comparing process, the master workpiece view comparisoning to the new ones. The differences of the pointclouds shows for us which workpieces are inside of the tolerance and which aren't. The items which placed on a production line can be inspected ('visually inspect') without people.

  The microstructure of metal sheets has strong relationship with the material and technological properties, and heavily affects the manufacturability of the resulting products. The present study aims to examine the coincidence between these mechanical and physical features, and different processing methods. Different material types of aluminium sheets had been symmetrically and asymmetrically rolled, and annealed by various preparation programs, and their effects on the anisotropy will be investigated through tensile tests, hardness tests and the EBSD-scanning of the microstructure.

  The presentation will demonstrate how the recent developed solutions in Industry 4.0 affecting the advancement of Manufacturing Execution System and analyzing what kinds of developed solutions that can define the growth of the next wave of these innovations. Moreover, providing overview of the MES development methods and standards, a comprehensive review of I4.0-related specifications for MES functionality will be presented. Furthermore, an analyzes made to show that MESs should seamlessly, safely and confidently connect all components of cyber-Physical Systems so that intelligent automated solutions are more possible, and that semantic metadata can provide contextual information supporting interoperability and modular development.
