Abstract
This work investigates the effects of different groove depths and groove widths on grinding performance in creep-feed grinding using circumferentially grooved grinding wheels. Using two constant-width diamond tools having widths of 3.2 mm and 1.7 mm, respectively, square-shaped grooves were cut into the surface of two separate grinding wheels. The grinding forces and spindle power decreased with respect to groove depth with diminishing reductions in forces and power as groove depth increased. It was found that there is little benefit in grooving deeper than ~400 µm. There was not a significant difference in results observed for the two different groove widths of 3.2 mm and 1.7 mm. Groove depth did not influence workpiece surface roughness. The coolant-induced force resulting from hydrodynamic pressure generation in the grinding zone decreased with respect to groove depth up until a certain groove depth. This groove depth was found to be ~400 µm.
