Following main S & T results/ foregrounds can be highlighted for the DynaMill project

• Module 1: Process Planning o Process planning CAM tool o Calculation of workpiece behaviour by RCMT model o Different spatial NC code partition approaches • Module 2: Adaptive clamping devices o Systematic know-how/ deeper technological understanding clamping devices for the machining of thin-walled workpieces o Passive damping concepts in clamping o Knowledge how to design passive dampening clamping devices o First promising active clamping concepts • Module 3: Cutting conditions o Systematic know-how/ deeper technological understanding regarding milling tools for the machining of thin-walled workpieces o Several innovative concepts/ prototypes of damping milling tools o Integration of High Damping Metals (HiDaMets) into the milling tool/ Know-how regarding HiDaMets • DynaMill Technology and Process Chain to layout or improve processes o In step 1 a first machining of the workpiece with standard or experience-based process parameters by usage of a DynaMill adaptive clamping device is conducted. o Afterwards (step 2), the measuring of calibration FRFs of the workpiece which is fixed in the machine tool is realized. o In step 3, the measured calibration FRFs are used as input parameter for the CAM planning module to be able to predict the dynamic behavior of the workpiece and to compile the needed NC code(s) for machining. o Finally (step 4), by additional usage of the milling tools which increase process stability, the optimized machining of the workpiece based on the »DynaMill-Technology« can be carried out. o Based on this approach the required thin-walled workpiece quality in conjunction with considerable reduction in manufacturing time and resource input can be achieved.
