Distortion Minimization in the Machining of AM-Structures

Additive manufacturing offers numerous advantages due to its near-net-shape design and the associated resources savings, but also poses challenges such as residual stresses. These lead to distortion, positional- and dimensional-errors, resulting in scrap or further post-processing. To counteract this, the article compares various alternating milling strategies with conventional approaches to show that the errors can be reduced by over 90 % with a suitable process design.
