Grinding Monitoring | SpringerLink
For monitoring with the help of fluid flows, the fluid is applied through a flapper nozzle, issuing air and measuring the flow resistance/pressure. For free chipping space, the flow resistance is smaller than for loaded or worn grinding wheels. Monitoring the flow field of the coolant is yet to be found in literature.
