Advanced grinding technology of new aircraft engine materials

Objective

The European aircraft engine industry is aiming to use new advanced materials, such as gamma-titanium aluminides and single crystals, which offer improved mechanical properties. By means of these advanced engines the fuel consumption will decrease, emissions and noise will be reduced. A manufacturing technology for those new materials which is efficient and highly reliable has to be developed. A key technology for the manufacturing sequence is the grinding technology. The innovative process, variant speed stroke grinding with super abrasive grinding tools, is proposed as a corresponding approach. For the realisation of this new grinding technology a concurrent development of a new machine tool concept, adapted super abrasive grinding wheels and an adaptation of the process itself is required. Focus is also on ensuring work piece properties while machining with the proposed technology.
