Abstract
The investigation of the effect of processing parameters on forming quality has been one of the highlight researches in spinning. The thickness distribution is an important criterion to evaluate the forming quality. Spinning force affects the processing and equipment design greatly. Combining with the FEA simulation and orthogonal test method, taking the maximum reduction ratio in thickness of workpiece and the maximum spinning force as the evaluation criterion, the esequence of the main forming parameters, such as the feed rate and roundness radius of roller, and the relative height of workpiece were analyzed based on an orthogonal scheme of three-factor and three-level. Both FEA simulation and experiment results show that, during the pentagonal section hollow-part spinning, the influence sequence on the maximum reduction ratio in thickness is relative height of workpiece, feed rate and roundness radius of roller; the influence sequence on the maximum spinning force is relative height of workpiece, roundness radius of roller and feed rate.
