that reduction process took place only on the larg-est size grain available among grinding media. The grain size of -4060 and -6080 tended to increase when the milling time was 60 min-utes, but the size of -4060 decreased until the milling time up to 210 minutes and was relatively unchanged until milling time was 360 minutes.
The loading of the grinding wheel and adhesion of the workpiece material to the cutting edges of the grinding tool are among the main reasons which limit the process efficiency when grinding ductile materials. The micro topography of the grinding tool changes drastically as a result of loading. Higher grinding forces and temperatures, poorer surface quality and process accuracy are the ...
