Abstract: The structure and the production process for flying shear machine are introduced first. Then, a quintic polynomial is applied to the design of an electronic cam system for the rotary knife axis in short materials cutting. The dimensionless equation for a quintic polynomial cam curve is deduced. Finally, the curve is plotted with the cam constructor integrated into Siemens engineering development software SCOUT and it is tested with a laboratory platform, which consists of a motion controller SIMOTION and motor drivers SINAMICS S120. The results show that the running stability of the flying shear machine and the position control accuracy of the rotary knife can be effectively improved by using the curve designed in this paper.
