Abstract: In order to solve the difficult problem of how to machine a deep, narrow, irregular and even curved cavity of difficult-to-cut material integral component, a new process of combined electrical machining with digitized manufacturing technology is put forward in this paper, that is an organic combination of numerically controlled electrochemical machining (NC-ECM) and numerically controlled electro-discharge machining (NC-EDM). By this advanced technology the irregular cavity of thin-wall and complex integral components on the aerocraft engines and the aerospacecraft engines can be machined, and with top quality, optimum efficiency, low cost and prompt response, which will have the important practical and wide application and show us the brilliant future.

Key words: integral component, irregular cavity, combined electrical machining, digitized manufacturing
