在模具设计时，模拟钣金件的成形过程是目前保证可行制造的标准。相比之下，模拟回弹及其计算机支持的补偿仍在开发中。通过实例说明回弹模拟技术的现状。将讨论并举例说明与回弹引起的形状偏差补偿相关的各种策略。对于内部零件，说明了使用计算机辅助模拟和回弹补偿的必要步骤。该示例展示了如何将回弹模拟集成到拉深工具的开发过程中，以便在工具生产之前根据回弹结果确定工具曲面的补偿。另一个例子演示了如何使用专用软件从回弹相关的形状偏差中快速确定新的拉伸模设计，以最大限度地减少或消除形状偏差。对形状偏差补偿过程的原理和可能出现的问题进行了说明。讨论了“回弹”补偿方法的可能性和局限性。在模具设计阶段，模拟板料零件的成形过程是目前保证可行制造的标准。相比之下，模拟回弹及其计算机支持的补偿仍在开发中。通过实例说明回弹模拟技术的现状。将讨论并举例说明与回弹引起的形状偏差补偿相关的各种策略。对于内部零件，说明了使用计算机辅助模拟和回弹补偿的必要步骤。该示例展示了如何将回弹模拟集成到拉深工具的开发过程中，以便在工具生产之前根据回弹结果确定工具曲面的补偿。另一个例子演示了如何根据回弹相关的形状偏差快速确定新的拉伸模设计，以最大限度地减少或消除形状偏差。
Simulating the forming process for sheet metal parts is currently the standard for guaranteeing feasible manufacturing at the time of tool design. In contrast simulating springback and its computer‐supported compensation is still under development. The status of the technology for simulating springback will be illustrated and demonstrated using examples. Various strategies related to compensation of shape deviations due to springback will be discussed and explained using examples. The necessary steps for the use of computer‐aided simulation and compensation of springback are illustrated for an inner part. The example shows how the simulation of springback can be integrated into the development process of a deep‐drawing tool to determine the compensation of the tool surfaces — based on the springback results — before tool production. Another example demonstrates how a new draw die design, that minimizes or eliminates the shape deviation, can be quickly determined from the springback‐related shape deviations using special software. The principle of the procedure for compensating for shape deviation and problems that could still occur are explained. The possibilities and limits of the “springforward” compensation procedure are also discussed.Simulating the forming process for sheet metal parts is currently the standard for guaranteeing feasible manufacturing at the time of tool design.
