Shear forming is a kind of spinning process which is used for manufacturing of the components that have a high weight to strength ratio. In this paper, the main parameters for manufacturing of a constant thickness conic shaped specimen have been extracted, using shear spinning process. To this regard a pre designed pre-form was used to improve the efficiency of the shear spinning process of the conic sample of this study. So, the main parameters of shear spinning of this specimen are derived using experimental and numerical tries. 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 experiment. Moreover, a new cup shaped preform has been used. Using of this preform can beneficially improve the quality of the final shape of the specimen. With comparison of the results of the experiments and numerical study, the optimized efficient forming parameters of the offered preform have been derived. It was observed that using of the designed preform will cause in better cone part specifications due to its close dimensional and geometrical specifications. It was shown that the proposed method can beneficially lead to better results in the shear spinning process.
