Abstract

The paper analyzes a regulatory document that specifies undercut forming and parameters. We herein show where, according to that document, it is recommended to form such undercuts, and hence dwell upon problems the document fails to tackle. Discussing a standard-undercut part, we demonstrate how and why underforging occurs and propose solving this problem by using movable clamps. We exemplify two model parts to show how movable-clamp forming can produce parts with non-standard undercuts. The paper presents the results of simulation and field experimentation for such model parts. The scheme and the technology of forming with a movable clamp are illuminated. The theoretical component of the shaping of the undercuts and the conditions necessary for eliminating defects during their shaping are described.
