Dynamic manufacturing of thin-walled work pieces by Milling process

Dynamic manufacturing of thin-walled work pieces by Milling process
Summary
Lightweight components are gaining importance in EU key industries with good market growth potential (e.g. aerospace, automotive and power generation). To achieve weight reductions, complex thin-walled structures are combined with high strength materials. However, the lower stiffness of work pieces leads to severe challenges during the milling process: • Difficulty to achieve high work piece quality, due to vibration and process forces, in industries that have very high safety and quality requirements (aviation, space). Therefore, in many cases manual finishing of the work pieces is required. • Achievement of acceptable work piece quality only through time and resource consuming trial and error identification of process parameters that circumvent critical process states. This often results in slow and inefficient processes. To overcome these challenges, DynaMill aims to achieve the complete control over the milling process of thin-walled work pieces. This will be realised through a threefold approach combining the development of process planning, adaptive clamping devices and improved cutting conditions. Subsequently, these three developments will be integrated in the DynaMill Technology as a platform. Throughout the project demonstration of intermediate and integrated solutions will play an important role. The impacts for industry include reduction of production time and costs, increase in process stability, reduction of process set-up time, reduction of wasted raw materials during set-up, improvement of tool life as well as reduction or even elimination of finishing operations. The project results will be disseminated widely through a number of measures such as a project website, publications, conferences and trade fair attendance and the organisation of a stakeholder workshop. The project partners, covering the entire DynaMill value chain, have concrete plans to exploit the project results to ensure a maximum benefit for European industry. For the project, a strong consortium consisting of two research institutes, four manufacturers of key technologies (CAM software, machine tools, clamping devices and tools) and four end users has been gathered.
