3D-mallien luomisen ja hallinnan kehittäminen venttiilien valmistuksen toimitusprosessissa

This master's thesis examines the development of 3D model creation and management in the valve manufacturing delivery process. The background to the work is the current state of 3D modelling, where the management of available 3D models is inconsistent and somewhat unstructured. The research focuses on 3D models of valve-actuator assemblies, as well as individual valve, actuator, and instrumentation components. The 3D models examined are primarily those delivered to customers, which are used, among other things, for space allocation and compatibility assessments. In the current operating model, the production of 3D models is largely manual, and their reuse and systematic management are limited by the high variation of components and the lack of standardized library structures. The aim of the work was to analyse the current 3D model creation and management process, identify its key challenges, and propose measures to enhance the efficiency and management of the process. The research was conducted as a case study, using a literature review as a theoretical background and to support the analysis. Empirical data were collected through semi-structured interviews and an analysis of the company’s current state. The results indicate that the more efficient use of 3D models is particularly constrained by an incomplete component library, inconsistent naming conventions, and fragmented storage of 3D data. The results form proposals for new operating models, which emphasize the use of a modular 3D component library and the introduction of standardized operating models. These proposals aim to improve the efficiency of 3D model creation and management in the valve manufacturing delivery process.
