Abstract:
Additive Layer Manufacture (ALM) is a technique whereby freeform structures are
produced by building up material in layers. RUAM (Ready-to-Use Additive Layer
Manufacturing) is an innovative concept for building large scale metal ready-to-
use parts. The design for RUAM has several process steps: the geometric design
of the parts taking the complex process behaviour of the arc welding process
into account; FEM to predict temperature and stress distributions to minimise
part distortions; and efficient robot tool path design. This paper covers these
essential design steps from a technical as well as practical point of view.
