Abstract
Two novel techniques were used to study the formation of ductile mode streaks during
diamond grinding (primary process) of germanium, silicon, and glass that aid the
secondary process of polishing. In the first technique asph~ric surfaces were generated
on Ge and Si at conventional speeds (5000 rpm). In the second technique high speed
grinding (100,000 rpm) of plano surfaces on glass and Si surfaces was carried out Form
accuracy, surface finish and ductile mode grinding streaks are discussed in this paper. It
was found that resinoid diamond wheels gave more ductile streaks than metal-bonded
wheels but better form accuracy was obtained with the latter. Transparent ground
surfaces were obtained more easily with Pyrex rather than with BK 7 glass, thus
necessitating very little time for polishing. Ductile streaks appeared in abundance on
germanium rather than silicon. Both the novel grinding techniques were used on CNC
machining centres.
