Numerical and experimental investigation of the effect of different parameters in shear spinning process of a conic sample

Shear forming is a kind of spinning process which can be used for manufacturing of components that have a high weight to strength ratio. this process can benefichially used in the conic or semi conic shaped specimens as it done in this paper. In this paper , the main parameters for manufacturing of a constant thickness conic shaped specimen have been extracted, using a pre-form design. These parameters include mandrel rotational speed , roller feed rate, tailstock pressure and friction ratio . To this regard, the optimized efficient parameters were extracted and the obtained data has been compared and validated with the experimen . Morever , a new cup shape preform has been used. With comparison of the results, the optimized efficient forming parameters of the offered preform have been derived . It was observed that using preform will cause in better cone part specifications due to it's close dimensional and geometrical specifications . It was shown that the proposed method can beneficially lead to better results in the shear spinning process .
