Dipl.-Ing. Matthias Ophey
Dipl.-Ing. Matthias Ophey studied mechanical engineering at RWTH Aachen University with a focus on production engineering. Upon graduation in 2013 he became a scientific research assistant in the gear department of the Laboratory of Machine Tools and Production Engineering (WZL). Opheyâ€™s research is dedicated to focusing on hard finishing of gears â€” especially generating gear grinding, and manufacturing-related properties.

- Prediction of Surface Zone Changes in Generating Gear Grinding (March/April 2015)
One process for hard finishing gears is generating gear grinding. Due to its high process efficiency, generating gear grinding has replaced other grinding processes such as profile grinding in batch production of small- and middle-sized gears. Yet despite the wide industrial application of generating gear grinding, the process design is based on experience along with time- and cost-intensive trials. The science-based analysis of generating gear grinding demands a high amount of time and effort, and only a few published scientific analyses exist. In this report a thermo-mechanical process model that describes influences on the surface zone in generating gear grinding is introduced.
