 note = {This paper presents a comprehensive view of the shearing procedure attained by detailed observations. In order to provide a fundamental approach to blanking operation in general a simplified shearing model with scissors-like tools is proposed and treated in detail in the first half of this research. According to this model, the penetration of the tool can be resolved into three imagined constituent components, and by means of this resolution, a new interpretation of the shearing performance has become possible. The same model is analyzed theoretically in which slip-line solutions consistent both kinematically and statically could be proposed. The phenomena occurring in various blanking processes will be adequately understood by taking account of their own external constraints and so modifying the scissors type shear. In the latter half, behavior of metal in the circular blanking has been investigated. A particular visioplasticity and a strain gauge method are employed for the observations of material flow. It has been found that the time when the ultimate crack initiates depends on the discontinuity of average radial velocities of material across a boundary of the product and the scrap.},
