Özet

This study was carried out in order to examine the influences of grinding wheel structure on surface roughness and grinding forces during surface grinding. Grinding tests were carried out using Al(2)O(3) grinding wheels at different table speeds and at different depth of cuts. The structures of the grinding wheels were 3, 5 and 7. AISI 1050 steel (50 HRc) was used as the workpiece material. For measurement of the grinding forces developed during grinding, a previously designed and constructed dynamometer was used. This dynamometer was also connected to a personal computer to save the grinding force data. The ground surface roughness values were also measured. Increasing grinding wheel structure resulted in significant increases in surface roughness values. However, its influence on grinding forces was marginal. The highest cutting force was obtained when grinding using grinding wheel having the lowest structure at the highest depth of cut.
