Chapter 3- Edge Requirements and Standards (eChapter)

Diverse definitions and approaches all contribute to the lack and necessity of edge requirements and standards, which is the focus of this chapter.  Clear communication of the desired edge condition is a low-cost method of reducing deburring and edge finishing costs.  Furthermore, costly scrap and functional problems arise from three aspects of the standards and edge requirements issue, which are discussed in this section.  Simply writing burr-free on a drawing inadequately reflects product needs. Standards provide a means of expressing which level of quality users and producers expect to receive or produce.  The Worldwide Burr Technology Committee (WBTC), a group of leading deburring authorities from the major industrial countries, provides seven different standards for use by small and large shops around the world.  Standard terminology is necessary to ensure better communication among individuals involved in the deburring process. This glossary provides the terms and definitions with which those individuals should be familiar. It can be appended to the sample standard included in this chapter or it can be appended to a company’s existing standard.
