Prof. Dr.-Ing. G√ľnther Gravel

G√ľnther Gravel is professor for production engineering at the Hamburg University of Applied Sciences. He is the head of the Institute for Production Engineering. For more than 20 years, Dr. Gravel has studied the measurement of gears. He is now developing software for the analysis of gear measurement and for the simulation of errors in gear manufacturing processes; in fact the software mentioned in this article is part of a software deviation analysis suite. This software can be used to visualize deviations, simulate errors, calculate corrections for the manufacturing process, and evaluate ripples on a gear surface. It has been developed in cooperation with Liebherr and Klingelnberg and is available with all Klingelnberg measuring machines.

  • Simulation of Deviations in Hobbing and Generation Grinding (September/October 2014)
    The hobbing and generation grinding production processes are complex due to tool geometry and kinematics. Expert knowledge and extensive testing are required for a clear attribution of cause to work piece deviations. A newly developed software tool now makes it possible to simulate the cutting procedure of the tool and superimpose systematic deviations on it. The performance of the simulation software is illustrated here with practical examples. The new simulation tool allows the user to accurately predict the effect of errors. With this knowledge, the user can design and operate optimal, robust gearing processes.
