Designed for resource-efficient, flexible, and automated production, a newly developed milling kinematic enables versatile, high-precision machining of materials ranging from fibre composites and aluminium to tempered steel — with manufacturing tolerances of up to 0.1 millimetres. This globally unique innovation was unveiled at Automatica.

The Fraunhofer Ifam in Stade, Germany, has developed a pioneering technology to improve the dynamics and precision of industrial robots, combining intelligent, model-based control strategies with innovative drive technologies and an optimized mechanical structure of the robot. This development enables dynamic errors to be compensated for and vibrations to be effectively damped. That significantly improves path accuracy, even at high feed rates and complex path movements.

A particular advantage is the optimized disturbance rejection which ensures constant precision even with highly dynamic process forces. This drive concept therefore enables machining with higher material removal rates as well as the ability to operate with higher jerk settings, both of which lead to a significant increase in productivity.
