Outline
In order to shorten the cycle of product, design and developent, procurement and production, construction of a flexible, efficient, low-cost and high-quality manufacturing operation system, digital twin technology is crucial. This article used an automotive welding production line as an example to elaborate the process of setting up a digital twin factory in Tecnomatix software. Using Tecnomatix series software, the digital model and process information were imported in the pre-planning process, the 3D process layout was carried out in advance, the accessibility of connection processes such as solder joints and gluing was simulated, the spatial static and dynamic interference as well as offline program output were analyzed and solved. Utilizing digital twin technology, the mapping and correlation of real factories in the simulation environment was realized. As a result, the on-site installation and commissioning was accelerated, the project cycle was reduced, the efficiency and quality of production line planning and design were improved.
