Published Article / The development of innovative products and their realisation by means of advanced manufacturing methods and process combinations is more becoming a key issue in international competitiveness. The industrial production is subsequently influenced ever more by the possibilities that Rapid Technologies -Rapid Modelling and Reverse Engineering, Rapid Prototyping and Tooling, Rapid Manufacturing can offer. Reverse Engineering (RE) is the process of digitising a physical object to obtain computerised data for further development as opposed to manufacturing a product from a digital model, e.g. CNC machining. This paper reflects experiences gained in the use of RE approaches for industrial applications, comparing specifically the use of tactile methods and digitising techniques based on photogrammetry principles. Process capabilities and the internal process chain are scrutinised. Practical case studies are presented and discussed with an emphasis on project lead times and dimensional accuracy obtained. Particular attention is paid to challenges related to surface recreation and manufacture of tooling for various components. The purpose of the paper is therefore to highlight the capabilities and wide range of applications for Reverse Engineering, while at the same time outlining pitfalls and limitations of this remarkable technology.
