ABSTRACT

Abrasive processes have been employed in manufacturing for more than a

100 years although the earliest practice can be traced back to Neolithic times

(Woodbury, 1959). The lack of machine tool technology meant that primitive

operations were mostly limited to simple handheld operations. An early

device for dressing a sandstone-grinding wheel was patented by Altzschner

in 1860 (Woodbury, 1959).
