According to the structural characteristics and cutting performance of titanium alloy TC17 large twist grazing blisk channel,“plunge milling+lateral milling around”high efficient and low cost method for rough machining was put forward. The large margin of blade passage in plunge milling was removed through lateral milling finish around the blade surface approximation processing to semi finishing or finishing convenient for subsequent leaf. The experiments show that compared with the traditional side milling slotting rough machining, the“plunge milling+ lateral milling around”mode can reduce tool costs, so that the rough machining efficiency can be increased more than 1 times.
