Nickel-based alloy GH4169has high temperature strength, good resistance tooxidation and hot corrosion. It has been widely used in the aerospacefield. However,it is very difficult to machine. D406A is low alloy high strengthsteel, it has good overall performance, it is widely used in the shell of aircraftengine. It is significant to make it suitable for machining these two difficult tomachine materials by sharpening the standard high-speed steel.
Firstly, after introducing the research condition of the t...
