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

In the present article, a comparative analysis of the widths and thicknesses of a test specimen prepared by punching a hydraulic press before and after sharpening the guillotine blades is made. The types of characteristics of the punch are considered. The comparative analysis was performed by a non-destructive method using a 3D computed tomography.
