Additive Layer Manufacturing for Aerospace Parts Essay Example for Free

Additive Layer Manufacturing for Aerospace Parts EssayES Technology has revea take that additive layer manufacturing (ALM) for direct part production has been embraced by a number of manufacturing sectors, not least the aerospace industry The ability to produce members in a range of materials including hot-work steels, stainless steel, cobalt chromes and Inconel, cocksure titanium and aluminium anyoys, presents the aerospace industry with too large electromotive force for direct part production using ALM. ALM has already been used to produce small and medium- size of itd aerospace lucks, and having realised the potential of the process, aerospace manufacturers are seeking to produce bigger, more heterogeneous parts. Material Solutions operates an ALM applications development centre with a particular focus on the aerospace sector.Carl Brancher of Material Solutions, said ALM in high-performance materials is well suited for complex thin-walled structures in gas turbines. Ho wever, as a new engine room it is not yet well at a lower placestood or validated by potential users and, like all manufacturing processes, to get the best from metal ALM requires the designer to understand the process capabilities and materials mechanical properties, he added. Brancher said Materials Solutions is bridging this cattle farm by providing make parts, consulting (principally to the aerospace market), and working with equipment and materials vendors to develop the technology for mass production.See moreMasters of chaff John Dryden and Jonathan Swift EssayThe collaboration between Material Solutions and its industry clients has so far led to the production of a range of components over the last three years. This programme has now reached the limit of component size that can be produced using the existing Material Solutions ALM systems. With the continuing pressure from aerospace manufacturers to develop the potency to produce larger parts, Material Solutions turned to Concept laser to explore the potential for building larger components using Concept Lasers M3 linear system. The fundamental principles of the M3 linear make it a novel development in the world of ALM.Unlike other machines the M3 linear does not have fixed optics but a gang of galvo scanning mirrors and linear direct drives to move the scanning head. Already used to build larger majority components, the M3 linear has all of the pre-requisites for up-scaling to enable production of the types of components envisaged by the aerospace industry. It is not only the physical attributes of the system that add themselves to production of large components but the process control and laser scanning strategy already demonstrable by Concept Laser, which will eliminate the potential pitfalls of accuracy errors on large components.Having established the potential of the M3 linear machine, Material Solutions set out to design a test component that would qualify sealed build criteria and whi ch could also be used to educate and inform aerospace designers of Additive Friendly design features and techniques. These implicate reducing supports and using larger flowing radii to assist in reducing the time to build and subsequently, component production and finishing costs. The test part incorporates many features such as small diameter holes, locomote features, thin rib sections and areas of thick material section all typically found in aerospace components.The superlative challenges for Concept Laser were that a component of this size had never before been built and added to this the part was ask in an unexpectedly short timescale. The finished component demonstrates the current capabilities of the technology in terms of size (300mm diameter), accuracy and surface finish. While this part does not yet satisfy the ultimate demands of aerospace manufacturers it clearly confirms the capabilities of the process, the climbable potential of Concept Lasers M3 linear machine an d the sound base which Concept Laser have for elevate development of the M3 linear for large aerospace components.There are also practical aspects to be considered when building large parts. Larger volume components require greater volumes of powder and hence a robust and stable plan to accommodate the weight. Having then built a large volume, and potentially very heavy component, safe and informal removal is essential.The M3 linear machine is built around a substantial fabricated framework and already incorporates a removable build module enabling the module and component to be easily positioned under an overhead crane if required. The success of this exercise and the current collaboration between Material Solutions and Concept Laser will be used to define the future strategies that will eventually see parts manufactured by ALM techniques leave the laboratory and take to the air.
