A coarse grift is required when the contact area is relatively large, as in surface grinding with cup wheels, cylinders or segments, to provide adequate chip clearance between the abrasive grains. As area of contact becomes smaller and the unite pressure tending to break down the wheel face becomes greater, finer grit wheels should be used.

The grinding pressure and back pressure are then released simultaneously. Figure 9 shows the grinding pressure and flow rate of the injector nozzle when the outlet is at atmospheric pressure during the ASFM process. The red dotted line represents the grinding pressure, and the black line represents the flow rate of the injector nozzle.

De-powdering. "De-powdering is a major issue, especially the smaller and more intricate the internal channels are," he says. "It's not trivial," especially when figuring out how to de-powder delicate parts with thin walls. Green parts are fragile and can break under too much pressure, so options like vacuums often won't work.
