An 8 in. diameter grinding wheel, 1 in. wide, is used in asurface grinding operation performed on a flat piece of low carbonsteel. The wheel is rotating with a surface speed of 5,000 fpm,depth of cut of 0.002 in./pass and cross feed (w) of 0.15 in. Thereciprocating speed of the workpiece is 20 ft/min., and theoperation is performed dry. Letting C = 300 per in2 and the ratioof chip width to average undeformed chip thickness equal to 20,estimate the undeformed chip length. Estimate theundeformed chip thickness. Calculate the required grinding power inlb*in/min. What is the amount of cutting force required for thisoperation?
