The HIMMOVAL project aimed to develop a new rapid metal removal concept under acceptable surface integrity for fabricating typical jet engine components made of high resistant super alloys that will be based on smart use of non-conventional machining methods, namely water jet technologies and low plasticity burnishing surface treatment, optimised conventional machining and a well-defined sequence of processes. The concept developed shows high productivity, low cost, the capability to create special geometries or cavities and the robustness to be translated to a real production situation. The feasibility of a radical improvement of material removal rate when using conventional machining with defined cutting edges through cryogenic cooling or creative machining strategies were also explored.

The generated results enabled optimum selection of removal processes together with their parameters under stringent surface integrity requirements for high resistant alloys. Moreover, the rapid removal concept contributed to deliver the geared open rotor demonstrator technologies addressed within the CSJU SAGE2 project to demonstration.

The HIMMOVAL consortium was integrated by 1 research organisation, 1 university and 1 SME.
