is an international standard that defines the rules for indicating the state of edges that are not explicitly dimensioned in a technical drawing. iso13715

According to ISO 13715:2017 , a burr is described as a material overhang. Measured Edge Length ( Use the symbol on a specific edge if

In the world of precision manufacturing and engineering drawing, sharp edges are rare. Nearly every machining, casting, or stamping process leaves behind a microscopic, and sometimes macroscopic, protrusion known as a . Controlling these edges is critical for assembly, safety, and functionality. Measured Edge Length ( In the world of

In applications like aerospace, medical devices, or high-precision automotive components, loose burrs can break off and damage critical systems. D. Cost Reduction (Deburring) By specifying a maximum allowable burr size (e.g.,

: Means either a burr or an undercut is allowed, with a maximum deviation of
