This work investigates the effects of material hardness and feedrate on burr dimensions created in grinding processes. Once burr have been formed, macrographs are taken and burr length, height, and thickness is recorded. Correlations between material hardness and feedrate were not consistent from one burr dimension to the next. The unhardened workpieces produced the smallest burrs and the next smallest were found on workpieces in the 57-59 Rockwell C hardness scale. There is evidence of the material having an ideal hardness value for producing minimum and maximum burr size.
