Principles of Incremental Forging. Phase II.

Abstract

The first phase of this program, established the feasibility of forging thin web-tall rib configurations typical of many airframe components by an incremental technique. In the second phase of the program, described in the report, the process was further developed by assuring accurate movement of the simultaneously indenting vertical and side anvils, and by feeding the workpiece with a manipulator developed for this task. The effects of process variables such as anvil length, bite, penetration and friction were investigated and the influence of process geometry on material displacement in a single indentation was explored in detail. In its present state of development, the process is capable of producing a thin web tall rib configuration with any number of stiffening cross ribs; rib and web thicknesses of 1/8 in. were achieved on the aluminum used as the simulating material.
