Cutting fluid emissions in grinding processes: influence of process parameters on particle size and mass concentration

Grinding processes are applied to achieve a superior workpiece surface quality and accuracy. In order to fulfill these requirements efficiently, the use of cutting fluid is indispensable. However, during the grinding process, the application of cutting fluids leads to the formation of cutting fluid emissions. These emissions can have a negative impact on the workers’ health, can be explosive, and can result into the drag-out of cutting fluid. This paper presents an experimental approach to evaluate the influence of process parameters on the formation of emissions and the particle size. It reveals a linear influence of cutting speed and cutting fluid volume flow rate as well as a significant impact of the material removal process.
