ICTM Aachen – International Center for Turbomachinery ManufacturingBarrel tools for thin-walled blade machining - facing further challenges beyond stability
How to design the machining strategy to fulfil the quality requirements for shape deviation?
Challenge and Motivation
- Due to the larger radius, barrel tools can realize higher width of cut by at the same time, achieving surface roughness values like ball end mills.
- Higher force leads to higher deflection of the tool and workpiece
Objective
- Development of a methodology capable to predict deflections produced by barrel tools.
- Experimental and simulation-based comparison of blade machining with barrels regarding deflection.
