Investigation of the incremental tube forming process and the influence of the vital process parameters on the quality of final product

Manufacturing structures with light weight and high strength in the industry is growing. Therefore, use of bent profiles and tubes in structures is increasing. In this paper, method of the incremental tube forming for bending tube is investigated. In this method using combination of spining and bending tube simultaneously improves the bending process for high-strength metals. The analytical model for incremental tube forming process is provided. The model is used for understanding the physics of the process and determine the amount of the required bending moment. In addition, numerical modeling of the incremental tube forming process for to forecast failures caused by bending is performed. The numerical modeling has been used to evaluate the effective parameters on the incremental tube forming process, such as feeding the second step, the rotational speed of spinning tool, feeding tube axis in the whole process and the effect of attack angle the spinning rolls and the results show The numerical model can be used to examine defects related to the speed of the process and Before producing the appropriate parameters to produce higher quality final product selected.
