Rostec recreated part of a Soviet machine tool using 3D scanning Experts from United Engine Corporation Rostec's Additive Technologies Center (ATC) have reconstructed the destroyed wheel structure of a Soviet lathe. The original drawings of the part were not preserved, so the engineers used 3D scanning and reverse engineering. First, experts collected the fragments of the steering wheel to restore it to its original shape, then scanned the part and created its digital model. The exact dimensions, which could not be determined from the fragments, were reconstructed by engineers during the design process. At the same time, the design is different: instead of six separate elements, which were previously made by injection, the engineers designed one monolithic part. This will eliminate the need for an expensive template and simplify assembly. The model was prepared for 3D printing from industrial polymer using layer by layer. The strength of the new design is checked by calculations, and the digital model is handed over to the customer to manufacture the part. Reverse engineering makes it possible to restore equipment components when the documentation is lost, and production in the traditional way requires complex and expensive equipment.
