Design of Numerically Controlled Dome Forming Machine.
Abstract
The report describes the work accomplished on a project to design the mechanical structure and numerical control system for a large capacity Dome Forming Machine, primarily for the production of large solid propellant motor hardware. The objective of this machine design is to provide a production unit capable of forming a two-inch thick disc shaped workpiece into ellipsoidal and hemispherical dome shapes, with a finish diameter from 85 to 160 inches. The approach to this objective is predicted on spinning and roller bending the workpiece. In the design of the numerical controlled machine, a control system was conceived that led to the selection of geometric curve fitting as the method to be used in generating the forming path. The computer program which employs an algorithm expression for the forming geometry, may be modified to correct for excessive forming forces without significant hardware modifications. (Author)
