Abstract
Machinability is a measure of ease with which a work material can be machined, and it is important in process planning and machining operations. Experiments of face milling four kinds of wrought superalloys were conducted at various cutting speeds from 30 to 90 m/min using coated cemented carbide tools. The tool life and tool failure modes were discussed, and two concepts of the cutting speed sensitivity and the critical speed at which the tool failure mode changes were presented. And then a new method to evaluate the machinability of difficult-to-cut materials was proposed. Based on this method, the machinability of the four kinds of superalloys was evaluated, and they could be ranked in such an order as GH605 < GH4169 < GH4033 < GH2132.
