The springback phenomenon in single point incremental forming has been discussed. Effects of forming angle and shape of the part are analysed using simple experimental method. Tool diameter, sheet thickness, step size, material parameters and the interaction of them are also analysed by using orthogonal test. The results show that the primary factor af- fecting springback is forming angle. In addition, springback is decreased when the specimen has a larger forming angle. The order of the four factors that influence springback is tool diameter, sheet thickness, step size and material parameters. The forming precision will increase if springabck is decreased by optimizing the forming parameters.展开更多
