| Popis: | This work investigates the effect of cutting conditions on the fatigue performance of the parts generated by turning process. There are various parameters such as cutting speed, feed rate and tool nose radius that are known for their significant impact on the quality of machined parts. The relationship between feed rate as a parameter of cutting conditions and the fatigue performance will be highlighted. In that case three batches of fatigue specimen were realized on an Alpha 1530xs CNC lathe, then tested on fatigue with a stress ratio R=0.1. The results are presented through S-N curves which illustrate the impact of the feed rate on the fatigue life performance. In fact, the feed rate affects the fatigue life performance spatially for low values of feed rate. The fatigue lifetime decrease with the increase of feed rate. |
