Burrs form due to the plastic deformation of materials during machining processes, such as milling and drilling. Deburring can be very difficult when the burrs are not easily accessible for removal. In this study, abrasive flow machining (AFM) was ad

Various types of burrs are formed during machining, press forming, and laser cutting. Deburring tools with cutting edges as well as wire brushes are widely used for deburring when the burr edges are accessible. When the burr edges are difficult to re
