PROBLEM AND SOLUTION1. The Industrial issue: Milling of thin walled work pieces

I4MS 2016: FOSTERING DIGITAL INDUSTRIAL INNOVATION IN EUROPE · 23rd and 24th of June · Amsterdam

Impeller is a part which is difficult to manufacture. The milling of the piece is faced to the very thin walls and vibration issues.

Consequences: appearance of vibrations which lead to limited cutting conditions and poor surface quality

Solution to improve the machining is to improve the fixture Solutions for intelligent fixtures need to be validated within a demonstrator

Solution of intelligent chuck that provides counter excitation Process adapted counter excitation reduces vibration Complex sensor system to monitor current oscillation pattern

and to provide input data for intelligent chuck

Results Sensor system is integrated in a clamping plate connected to the fixture Sensor data analysed by controller to trigger actuators which provide

counter excitation
