Effects of grinding parameters on residual stress of 42CrMo steel surface layer in Grind-hardening

Abstract: Abstract-Grind-hardening is an integrated manufacturing technology of surface-quenching and grinding process. The residual stress is one of the main characteristic parameters of grinding-hardened surface quality. On the basis of the grindinghardening test, influences of the grinding speed, the grinding depth and the feed speed on residual stress in grinding-hardened layer of 42CrMo steel were systematically studied. Basic regularities of above-mentioned grinding parameters on residual stress and its relationsh… Show more

“…ábra) [6], bár jellege a köszörülés paramétereitől függően igen jelentősen változhat (1. ábra). Számos kutatás számol be arról, hogy a köszörülés technológiai paraméterein keresztül (fogásmélység, sebesség, előtolás, abrazív szemcse anyaga, hűtési mód és folyadék típusa) nagymértékben befolyásolhatjuk a kialakuló maradó feszültségek nagyságát, sőt jellegét (húzó, nyomó) is [5,7,8]. A kovácsolás kisebb mértékű [10], az ütőtestes megmunkálások a fémek felületi rétegében jelentős nagyságú nyomó maradó feszültséget alakíthatnak ki (3. ábra), amelyek növelik a munkadarab kifáradási határát és élettartamát [11,12].…”

“…However these technics cannot be directly applied to gear teeth surfaces improvement due to the specific geometric shape of gear teeth. While the phenomena which occur during machine cutting or abrasive machining process and their effect on the surface layer are widely discussed in the available references [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ] and the industry norms applied in the assessment of microstructure, the question of machining prior to case carburizing of the surfaces to be exposed to considerable and dynamically variable loads is less extensively detailed in research work. However, it is known, that certain external factors related to machining could result in local changes in the carburized case parameters to a point capable of negatively affecting the mechanical performance of the carburized case.…”
