An extension from qualitative to quantitative flow measurements of the cooling lubricant supply during grinding is achieved using shadowgraphy and particle image velocimetry. As a result, the measurement results in a grinding machine show the general feasibility of optical measurements despite severe optical disturbances in the two-phase flow. While using tracer particles enables closer measurements to the grinding wheel, both measurement approaches provide similar results. This enables investigations for the identification of flow characteristics, which are responsible for an efficient cooling.
