The final object of this study is to establish the operation standard of face milling with carbides in terms of tool life. As well known, milling process involves various complicated factors to govern the tool life, whereas most of them have not been clarified. In this report, the most suitable carbide grade, the best combination of tool shape, the effect of cutting speed, feed, depth of cut, engage angle and width of work material or frequency of shocks upon the tool life are investigated. It has been stressed that the feature of the tool wear in carbide milling is characterized by the fact that the shock against the tool tip due to the engagement with work material plays an important role in the process of the tool wear, whereas the temperature plays only a minor role. Summarizing the test results, it can be concluded that the key point of face milling with carbides is how to prevent chipping from every standpoint
