Workpiece Edge Beveling to Control Formation of Burr in Face Milling

Presence of burr at the edge of finished workpiece often leads to difficulty in assembly operation and injury to operator necessitating incorporation of additional processes of deburring. Exit burr formation by milling usually occurs when cutter moves out of the work piece. One method for minimizing this problem is to prevent the tool from exiting the workpiece while removing material. Burr formation can also be reduced considerably by edge beveling of the workpiece. In the present work, the influence of beveling the exit edge of the workpiece on the burr formation in milling has been experimentally investigated to find out the optimum condition to control the formation of burr.
