| Abstract: | Classification and forming principle of different kinds of odd-shaped pinholes are introduced.It is pointed out that the non-circular curved surface pinhole is the development direction of pinhole structure of the high-speed high-load pistons.The machining method of odd-shaped pinholes and problems are analyzed,and limitations of the existing machining technology are pointed out.A new magnetostriction material boring bar is presented for precision finishing of different types of odd-shaped pinholes,and structural optimization and test validation are carried out.Test results indicate that the optimization results are rational, and it is a new way for odd-shaped pinhole machining. |
