Abstract

Procjena sposobnosti procesa bitan je dio u razvoju proizvoda koji daje uvid u moguće nesukladnosti kod procesa sklapanja. Nakon izrade dizajna proizvoda i definiranja tehničke dokumentacije pristupa se postupku analize tolerancija te zatim s rezultatima analize pristupa se procjeni sposobnosti procesa sklapanja. Za izradu analize tolerancija kod složenih sklopova s velikim brojem komponenti, danas se koriste razni programski paketi koji se nazivaju računalom potpomognuta analiza tolerancija (Computer Aided Tolerancing - CAT). U prvom dijelu ovog rada opisan je analizirani proizvod, tj. jedinica za distribuciju električne energije, njezina funkcija, pregled komponenti. Također izneseno je što je postupak analize tolerancija i procjena sposobnosti procesa, Šest sigma metodologija. Opisan je korišteni CAT programski paket i Monte Carlo metoda prema kojoj radi. U drugom dijelu je gore navedeni postupak analize tolerancija primijenjen na primjere iz proizvoda pomoću CAT programskog paketa 3DCS te su izneseni i komentirani rezultati procjene sposobnosti procesa.

Abstract (english)

Process capability assessment is an essential part of product development that gives us insight into possible non-conformities in the assembly process. After creating the product design and defining the technical documentation, the tolerance analysis procedure is started, and then, with the results of the analysis, we start assessing the capability of the assembly process. Various software packages called CAT (Computer Aided Tolerancing) are used today to perform tolerance analysis of complex assemblies with a large number of components. In the first part of this thesis, the analyzed product is described, i.e. the electricity distribution unit, its function, component overview. It was also presented what the procedure of tolerance analysis and process capability assessment is, as well as the Six Sigma methodology. The CAT softwear used and the Monte Carlo method according to which it works are described. In the second part, the above-mentioned tolerance analysis procedure was applied to an example from a product using the CAT software package 3DCS, and the results of the process capability assessment were presented and commented on.
