The process often involves significant costs and lead times to achieve the required precision. Machining lead times are further amplified by the high demand. Funded by the Natural Sciences and Engineering Research Council (NSERC) and the Consortium de recherche et d\u2019innovation en a\u00e9rospatiale au Qu\u00e9bec (CRIAQ), the objective behind the MANU-1707 project titled \u201cCr\u00e9ation de strat\u00e9gies d\u00e9monstratrices de conception et de fabrication hybrides pour l\u2019outillage a\u00e9rospatial\u201d was to evaluate and integrate AM into tooling production processes when machining aerospace parts while reducing costs and production lead times.<\/span><\/p>\n<h2><span class=\"fontstyle3\"><br \/>\n<\/span><span class=\"fontstyle0\">The challenge<\/span><\/h2>\n<p><span class=\"fontstyle0\"><br \/>\n<\/span><span class=\"fontstyle3\">AM is often considered too expensive when producing parts that do not provide a great deal of value-added. Inconel and titanium aerospace parts with complex and optimizable geometries, however, are often considered ideal candidates for AM. Machining jigs made from 6061 or 4340 aluminum tend to be less so. This is partly due to the lower cost of the material intended for machining when producing the jig; machining 90% of a steel part is typically less challenging than doing the same for a titanium part. If we consider machining costs alone, a commonly used AM design rule states that a part produced through machining will generally be less expensive than one produced through AM. Plus, a jig\u2019s geometry often shows less flexibility to topological optimization due to geometric constraints from the parts they hold, as well as by other sections of the jig. The jigs analyzed in this case study involved high production costs, which the project sought to reduce. It should be noted that these jigs belonged to a set of comparable fixtures that could be optimized through similar methods.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p class=\"link-btn-style btn-yellow\"><a href=\"https:\/\/cqfa.quebec\/en\/etude-de-cas_howmet-aerospace_partie-1_ang-2\/\" target=\"_blank\" rel=\"noopener\">Read the case study<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Centre de m\u00e9tallurgie du Qu\u00e9bec (CMQ), Howmet Aerospace, A7 Integration, Coalia, Electro-Kut, \u00c9cole de technologie sup\u00e9rieure (\u00c9TS), Sph\u00e8reCo Technologies, TRAF Produits Industriels.
