Survey of the geometric characteristics of a test specimen before punch sharpenings

  • 1 Institute of Information and Communication Technologies, Bulgarian Academy of Science, Sofia, Bulgaria


This article analyses the widths and thicknesses of the test specimen after operating the punch before sharpening the guillotine blades. The principle of operation of a 3D computer tomograph with an accuracy of 3μm is considered. The analysis will be performed in two ways: by using a micrometer and a caliper and by using a 3D computed tomography for determining the width and thickness
