Abstract: This paper presents an experimental remeshing process for the large strain analysis of fine-blanking. The research is to be carried out mainly because the severe and localized deformation of fine-blanking greatly obstructs the measurement of strains. In order to solve this problem, a new experimental remeshing process was developed to measure the strain in the major deformation areas of fine-blanking. Without this newly developed process, a more intensive and practical strain analysis of fine-blanking could not have been achieved. Therefore, a study of this remeshing process, with a step increment of 20 per cent, until the total punch penetration is 80 per cent of the material's thickness, is to be performed to verify its effectiveness. Low-carbon steel sheets of JISG3101 were used to split blanks. As a consequence, findings showed that an increase in the total punch penetration will clearly induce an exponential increase in the effective strain, and the severity of deformation will be augmented with the increase in the total punch penetration.
