Deformations of cutting tool and clamping devices and workpiece fixture devices and of the impact on cutting edge and workpiece deflections targeting on their optimization and compensation (A01)

• Subject Area: Engineering Design, Machine Elements, Product Development ; Production Automation and Assembly Technology ; Metal-Cutting and Abrasive Manufacturing Engineering
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 174223256

The TP A01 focuses on solution strategies for the compensation and correction of radial and axial thermal tool errors under consideration of the influence of different cooling strategies. The models developed in phase 2 will be extended to identify thermal characteristics. With these results and a tactile temperature sensor system, a real-time capable correction method is developed and tested on real machining processes. In addition, the change in position of the workpiece due to thermal deformation of the fixture will be investi-gated.
