In the forming grinding of a cemented carbide microdrill, edge burrs are generated. To explore the formation of the edge burrs, the grinding parameters, such as feed rate, grinding depth, wheel service time, and wheel rotation, are analyzed experimentally. Results show that the burrs on the microdrill edge are caused by material plastic flow and cumulative effect of deformation under the ...

Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

When Grinding Is Like Turning Modern Machine Shop. It is able to do this because the wheel is very thin and the grinding forces imparted into the workpiece are very low compared to plunge grinding with a wider wheel, especially when grinding wheel peripheral speeds are in the 80 to 180 m/sec. range (40 to 50 m/sec. are common with typical cylindrical grinding operations).
