same way. When the cutting process begins slightly differently \u2014 even by a small margin \u2014 the stress distribution changes. One edge may take more load earlier, while another engages later. Over thousands of cycles, this difference becomes visible as uneven wear. Small deviations in profile, edge sharpness, or angle accuracy can alter how the punch contacts the material. And once contact changes, the load path changes as well. This is especially critical in high-speed production, where even minor inconsistencies are amplified. Punch wear is not random.It reflects how force moves through the tool.
