Insert milling tools are used for processing cost reduction in hard metal cutting. However, tool life will be shorter because insert tools have tip runout caused by machining error of cutter body and insert tip casting problem. In this paper, we have developed a control method for longer tool life by adjusting feed rate for each tip runout and by reducing cutting speed temporarily. The experimental results described here show how this method effectively improves tool life in machining difficult-to-cut materials.
