Carburizing is a commonly used for increasing the strength and wear resistance of gearing. Carburizingfollowed by quenching leaves residual compressive stresses which aid resistance both to contact and bending stresses.Residual compressive stress is generated in the carburized case because of the delay in surface martensite formation dueto the high surface carbon content. After carburizing it is necessary to finish the gear by process such as grinding. Thesefinishing processes develop the precise geometric form required while improving the surface finish. Finishing processchange the residual stress imparted by carburizing and subsequent heat treatment processes. This paper focuses on toevaluate the variation of residual stress distribution of the carburized gear due fine grinding operation. Residualstresses were measured at different locations on the tooth from each gear using X-ray diffraction method. Numbers ofmeasurements were made in this study to determine the variation of residual stresses on the surface prior to and aftergrinding. The results are compared with the un-finished carburized gear on residual stress values.
