Application of WAAM additive manufacturing technology for reverse engineering of a product

Abstract

Most machine-building enterprises need to manufacture products that are slightly different from standard products in production in order to check how effective a change in a particular property or configuration is. In this case, WAAM additive technologies allow you to manufacture a product without additional design of complex tooling, unlike traditional methods, which reduces the time spent on production and reduces the cost. This article will present the pro-cess of reverse engineering for a finished product with the manufacture of a new one with a different material in order to check the feasibility of this change. The purpose of the work is to carry out the reverse engineering process to obtain a new product from 08G2S steel, replacing the old cast product from 110G13L and the manufacture of a sample for additional hardening surfacing with flux-cored wire. A robotic complex CRP-RH1-10 was used as an installation for additive electric arc growth. For the manufacture of the beater, Sv-08G2S wire with a diameter of 1.2 mm was used. After the model was created and agreed upon with the customer, electric arc growing was performed, after which the product was cut off from the lining. Smudges and irregularities formed during the growing process were removed. Then the product was sent for mechanical processing on a turning and milling machine. The total time for growing the prod-uct was 12 hours. The work performed demonstrated the effectiveness of the WAAM additive technology for the manufacture of individual products and reverse engineering using a robotic complex, including for products of varying degrees of complexity
