Paper 8: Study of the Finish Produced in Surface Grinding

Abstract
The finish produced in reciprocating surface grinding was studied experimentally and analytically. The 2 n factorial design of experiments technique was applied to determine the relative importance of a large number of variables on the centre-line average (c.l.a.) surface roughness produced without spark-out. The most important variable was found to be table speed which should be low for best finish. The following variables were but one-half to one-third as important as table speed and should be adjusted in the direction indicated for good finish. The peak-to-valley roughness was found to be from four to six times the arithmetic roughness over the entire range of grinding conditions investigated.
