Elimination of burr formation during end milling of Polymethyl Methacrylate (PMMA) through high speed machining

A burr is a raised edge or small pieces of material remaining attached to a workpiece after it has undergone machining. The Burr, Edge and Surface Technology (BEST) Division, the Society of Manufacturing Engineers defines a burr as “an undesirable projection of material that results from cutting,...
