Ad-Proc-Add project publishes results on the process chain of additive-subtractive manufacturing

April 26, 2023

In the Advanced Processing of Additively Manufactured Parts (Ad-Proc-Add) project, researchers have developed new tool concepts, strategies for Additive Manufacturing metal components, sophisticated post-processing methods, system prototypes for monitoring devices, and additional services, all compiled in a digital compendium. The knowledge acquired is intended to aid system and service providers in developing new products with enhanced functionalities, while empowering end-users to implement ASM process chains with greater productivity and improved economic and ecological efficiency.

The Ad-Proc-Add project consisted of a systematic and comprehensive investigation of additive and subtractive manufacturing (ASM) process chains in order to achieve a detailed understanding of influences and interdependencies of parameters, strategies and boundary conditions with respect to the material and workpiece properties of additively manufactured and post-processed parts in various applications.

The goal of the project was to achieve the capability to adjust the workpiece properties (e.g., geometric, surface, and subsurface characteristics) throughout ASM process chains so that pre‐defined requirements can be fulfilled. This would enable a targeted layout and implementation of ASM process chains in various industrial sectors. For this, an international approach of research associations and institutes was chosen, which combined the necessary experience in the areas of Additive Manufacturing, material removal processes, process monitoring and control, machinery and equipment, simulation, and optimisation as well as energy efficiency analysis.

Ad-Proc-Add was carried out by nine research institutions from Germany, Austria, Belgium and Switzerland is supported by a user committee comprising SMEs from all relevant market sectors. The coordination of the project was carried out by the Forschungskuratorium Maschinenbau e.V. (FKM), whilst technical management was conducted by the Institute for Machine Tools (IfW), University of Stuttgart.

The digital compendium is available for free download from the project website.
