Quality of cut faces of (sheet) metal parts after cutting@ blanking@ trimming or piercing; general introduction@ characteristic values@ materials

This document establishes a standardized framework for assessing the surface quality of metallic sheet components following machining processes such as shearing, blanking, trimming, or punching. It defines a comprehensive set of terminology and characterizes the geometric and morphological properties inherent to these cut edges. The text provides detailed guidelines on identifying and measuring specific features that arise during manufacturing, ensuring consistency in evaluation methods across the industry. By specifying the characteristics and underlying materials relevant to these operations, it enables engineers and technicians to systematically analyze edge conditions. The content focuses on the technical parameters required to describe the state of the surface, facilitating clear communication regarding quality expectations and production outcomes. This approach supports the uniform application of criteria in industrial settings without introducing subjective interpretation, thereby promoting reliability in quality control procedures for metal fabrication.
