A Comparative Study of Experimental and Simulation Approaches For Flow Forming Of Circular Aluminum Tube (2219)
Keywords:
Flow forming, simulation, experimentation, forming parametersAbstract
Precision thin walled Al tubes are required for several critical applications. Flow forming is commonly used to manufacture such components as it is an economical and efficient process. In this process, wall thickness of pre-form is reduced and the length is increased with out changing inner diameter. The dimensional accuracy is largely affected by various forming parameters such as mandrel speed, roller feed, and roller geometry. This paper deals with important findings during the production of Al tubes for getting the optimum parameters. The experiments were conducted on two roller CNC flow forming machine. The present work compares the results obtained by the experimental approach and the simulation process carried out by DEFORM-2D. The experimental results exhibited a good agreement with the simulated values.
