Abstract: 
The machining process 'grinding' is generally critically assessed concerning the amounts of heat produced during the process operation. Relatively high friction effects in abrasive machining cause heat generation which can lead to thermal damage in the surface layer of machined parts. Furthermore an inefficient cooling and lubrication system can result in higher tool wear and surface roughness. Therefore the application of cooling lubricants is of utmost importance in grinding. Usually the optimization of the coolant supply system including the selection of the coolant itself is based only upon empirical know-how or practical trial-and-error-tests. Systematic approaches using broader experimental investigations and thus resulting optimized grinding parameters or using fluid mechanical investigations in the coolant supply nozzle or in the grinding gap are not or only rarely applied. This Dr. dissertation presents three methods for the investigation and optimization of cooling lubrication in grinding of the ball bearing steel 100Cr6: 1) modeling and process optimization using experimental data, 2) flow visualization in fluid supply nozzles and 3) grinding fluid pressure measurements in the contact zone.
