A Study on the High Speed Machining of Major Structure in Aircraft

The study on high speed machining was conducted for wing and rib parts of major structure in aircraft in order to investigate a optimal cutting condition and machining method using a high speed machine with 33,000rpm. Preliminary tests, such as high speed cutter test and spindle vibration test of high speed machine, were performed and the high speed machining was conducted in 3times after the preliminary test results were applied to a NC program for manufacturing.
