Taking granite as machining object,we studied influence of cutting speed,feed rate and depth of cut on tool life by means of variance analysis and regression analysis. The result indicated that cutting speed had a more remarkable effect on tool life; feed rate ranked the second; depth of cut had no significant influence on tool life. Scanning electron microscope (SEM) was used to observe wear morphologies of gravers. It was found that abrasive wear was the main wear mechanism.展开更多
