Abstract

This paper presents the results of a numerical simulation study on the influence of process parameters on the deformation ability in the nosing process from a hollow cylindrical workpiece made of Bimetal F11. The Deform 2D software is used in numerical simulation. The process parameters studied include coefficient of friction (µ), die angle (α), and nosing ratio (K_T). The deformation ability is evaluated through the wall thickness difference Δs (mm) of the product. The response surface method (RSM) aims to determine the relationship between input parameters and the objective function. ANOVA analysis of variance shows that wall thickness difference decreases when increasing the friction coefficient, increasing the nosing ratio, or decreasing the die angle. The optimization algorithm determines the minimum wall thickness difference to be 0.05 mm at the coefficient of friction of 0.15, the die angle of 15°, and the noising ratio of 0.8. The obtained results allow analysis and selection of reasonable process parameter ranges of the forming process, serving to manufacture details as case, bullet of infantry cartridges.
