An experimental approach to temperature measurement in the contact zone when grinding brittle-hard materials

Temperature is an important process factor in grinding. Cryogenic cooling has proven to be very successful in metal machining, for example, as oxidation is prevented by lowering the temperature level. This enables significantly higher cutting speeds and longer tool life. In our research, we aim to determine whether similar effects occur when grinding brittle-hard materials, which is why the temperature in the contact zone is explicitly examined here. This article presents a very simple and extremely cost-effective approach using a germanium window and an infrared temperature sensor. It explains how the system is constructed, what results can be achieved with it and how the system compares to other commercially available approaches.
