Abstract

V podjetju, kjer se izdeluje polizdelke za vgradnjo v visokotlačne ventile, smo aktivno sodelovali s skupino tehnologov. Želeli dvigniti nivo proizvodnje na oddelku. Cilj nam je bil postaviti sistem, ki omogoča popolno predvidljivost in sledljivost, hkrati pa omogoči natančno napoved delovnega procesa. Delali smo na projektu integracije računalniško podprte obdelave na obdelovalne stroje. Pri popisu projekta smo se odločili za eno stružnico. Gre za stružnico Nakamura Tome NTY3-150. Delo je obsegalo razvoj in testiraje specifično definiranih vmesnikov na CNC strojih in kreacijo digitalnega okolja v katerem deluje dvojček stružnice. Ta virtualni pripomoček seveda ni popoln, zato se pričakuje odstopanja, ki niso znana. Njegovo natančnost smo tudi preverili. Delo je potekalo segmentno, od modeliranja, postavitve tehnologije, do simuliranja na dvojčku. Sledilo je testiranje v realnem okolju, v katerem smo izvedli te iste operacije simulirane s strani dvojnika. Ugotovili smo, da z uporabo manjšega korekcijskega faktorja, z virtualnim dvojnikom dobimo zanesljive in ponovljive končne čase obdelave.

Secondary title: Using digital twins on three-turret lathes
Secondary abstract: In a company that manufactures semi-finished products for installation in high-pressure valves, we have been actively working with a team of technologists. They wanted to raise the level of production in the department. Our aim was to set up a system that allows complete predictability and traceability, while at the same time allowing accurate prediction of the workflow. We worked on a project to integrate computer-aided machining on machine tools. When taking stock of the project, we decided on one lathe. It was a Nakamura Tome NTY3-150 lathe. The work consisted of developing and testing specifically defined interfaces on CNC machines and creating a digital environment in which the lathe twin operates. This virtual tool is of course not perfect, so variations are expected and unknown. Its accuracy has also been verified. The work was carried out in segments, from modelling, to technology set-up, to simulation on the twin. This was followed by testing in a real environment, where we performed these same operations simulated by the duplicate. We found that by using a smaller correction factor, the virtual duplicate yielded reliable and repeatable final processing times.
