Geometrical model of a conical angled stitching

This dataset contains the geometric model of the part of the case study of the following conferral article: Hybrid manufacturing ranges: Intermediate geometric models for the realization of complex parts This article deals with hybrid manufacturing sequentially combining Direct Energie Deposition process additive manufacturing and machining operations. WAAM additive manufacturing makes it possible to produce complex parts at low cost (compared to other additive manufacturing technologies) and with a high deposition rate. However, the surface condition obtained remains non-functional, so it is necessary to remanufacture these surfaces. On the other hand, some parts of complex geometry produced in a unitary way are not machineable in the mass because of accessibility problems. Hybrid manufacturing (additive manufacturing, machining) can make it possible to carry out these types of parts. The division of these complex geometries into segments manufactured sequentially makes it possible to increase accessibility in machining, and to facilitate deposition into additive manufacturing. The alternation of additive and machining operations raises problems with the quality and stability of processes (projection on finished surfaces, collapse). In order to avoid these defects, a more massive/gross part (protuberance) can be left voluntarily, at the interface between the segments. In the case of complex geometries, the creation of intermediate geometric models becomes necessary in order to calculate the trajectories to manage these interfaces. By producing a proof of concept, we show the feasibility of a hybrid manufacturing range for a complex tubing. We show the interest of these intermediate geometric models. ***
