Conventional blanking is the single-stroke shearing of closed contour profiles. However, the blanked pieces have inherent errors like fractured cut surface and blank dishing necessitating further sizing and/or finishing operations. Fine blanking is a more precise version of the blanking operation with lesser errors such that post-forming steps required will be minimal. Thus, it is an ideal candidate for manufacturing precision machine components. This review paper starts with the introduction to the process. Then, studies aimed at the analysis of fine blanking tooling and process parameters and their effect on fine-blanked part characteristics are presented. Inferences from studies on the design of equipment for fine blanking, deformation mechanics involved and the fine blanking performance of different materials are also discussed. The use of finite element simulation studies to understand the process better has also been determined. Various reported strain measurement techniques are then discussed. The recent improvement in techniques like in situ digital image correlation enables accurate experimental measurement of strain in the shear zone which can be used to validate the findings from FE simulations. Fine blanking process modifications that aimed at cost reduction or improvement in product quality are summarized as well.

传统的冲裁是封闭轮廓轮廓的单行程剪切。然而，落料件具有固有的误差，例如切割表面断裂和落料凹陷，这需要进一步的上浆和/或精加工操作。精细落料是落料操作的更精确版本，具有较少的错误，因此所需的后成型步骤将最少。因此，它是制造精密机械零件的理想选择。这篇综述文件从流程介绍开始。然后，提出了旨在分析精冲工具和工艺参数及其对精冲零件特性的影响的研究。还讨论了对精冲设备设计，所涉及的变形力学以及不同材料的精冲性能的研究推断。还已经确定使用有限元模拟研究来更好地理解该过程。然后讨论了各种报道的应变测量技术。诸如原位数字图像相关技术的最新改进使得能够对剪切区中的应变进行精确的实验测量，从而可以验证有限元模拟的结果。还总结了旨在降低成本或提高产品质量的精细冲裁工艺修改。诸如原位数字图像相关技术的最新改进使得能够对剪切区中的应变进行精确的实验测量，从而可以验证有限元模拟的结果。还总结了旨在降低成本或提高产品质量的精细冲裁工艺修改。诸如原位数字图像相关技术的最新改进使得能够对剪切区中的应变进行精确的实验测量，从而可以验证有限元模拟的结果。还总结了旨在降低成本或提高产品质量的精细冲裁工艺修改。
