Computed Tomography in NDT and Metrology for Additively Manufactured Aerospace Components

摘要

This study conducted by RAMEM S.A, TRUMPF Laser- und Systemtechnik GmbH and YXLON International GmbH investigates the joint impact of additive manufacturing (AM) in combination with computed tomography (CT) on the production process of engine rakes. Rakes are the support parts for a series of tubing that are connected to sensors which analyse the engine behaviour. Their high required load capacity as well as their complex geometry made them a particularly interesting case study. Rakes conventionally are produced by using subtractive manufacturing, i.e. they undergo a series of different machining steps, assembly and welding along with dimensional inspection and NDT on the sub-assemblies. This manufacturing complexity with its numerous production steps results in costly parts with long processing times which are a hurdle for the aerospace industry.
