Abstract

Aquantitative relationship is demonstrated between the coefficient of static friction and the milling process parameters. Different levels of surface roughness are obtained by varying the spindle speed, depth of cut and feed which is followed by measurement of surface roughness using stylus profile meter. The corresponding coefficients of static friction are measured for all specimens using inclined plane method. The surface roughness (Ra) value is found to increase with increase in feed rate and depth of cut and vice-versa. The surface roughness is found to marginal decrease with increasing spindle speed. The coefficient of static friction is found to decrease with increasing Ra values.
