Problems solved by technology

This sag or deformation can cause the actual dimensional characteristics of the incrementally formed part to deviate significantly from the desired or design-intended configuration
Additionally, residual stresses in progressively formed workpieces can lead to undesired deformations that can lead to dimensional inaccuracies
Dimensional inaccuracies can accumulate as the workpiece is formed

Abstract

The invention discloses a method for gradually forming a workpiece. The method may include incrementally forming a reinforcement on the workpiece and incrementally forming a component on the workpiece. The gap between forming tools can be reduced to reshape the part.

Description

technical field [0001] The present invention relates to a method of incrementally forming a workpiece. Background technique [0002] In incrementally forming a workpiece, the workpiece is formed into the desired configuration through a series of smaller incremental deformations. Small incremental deformations may be provided by moving one or more tools along and against one or more surfaces of the workpiece. Tool movement may be performed along a predetermined or programmed path. Additionally, the tool movement path can be programmed in real-time adaptively based on feedback, for example, from measurements from sensors such as load cells. In this way, incremental forming may be performed step by step without removing material from the workpiece while moving at least one tool. Further details of such a system 10 are disclosed in US Patent Application Serial No. 12 / 369,336, which is incorporated herein by reference in its entirety. [0003] In a fixture assembly, an unsupp...
