Analysis of the Radial Forging Process for Manufacturing Rods and Tubes

Abstract

The slab method of analysis was applied to study the mechanics of radial forging of rods and tubes. The analysis has been computerized by taking into account the effects of strain, strain rate, and temperature upon the flow stress of the material being forged. Forging loads were predicted for selected conditions in radial forging of rods at room temperature. The predictions were compared with experimental data, published by another investigator. The results indicate that the analysis developed in the present study is sufficiently accurate for practical purposes. A parametric study was conducted to determine the relations between various process variables in hot radial forging of tubes.
