Even in a fully automated factory, many deburring operations are carried out manually . To remove or minimize the burreffectively or automatically, understanding of the burr formation which occur at the exit stage of machining is necessary. Burrs can be formed on the feed mark ridges an the edges of the machined parts in machining operations. These burrs are underirable in terms of the surface quality, the precise dimensioning of the machined parts and the safety of operators. This paper demonstrates the effectiveness of using end mill tool on minimizing the exit burr formation in machining . In particular, the experimental relationships between the size of exit burr and the cutting parameters are established in end mill machining . Methods to control the size of exit burr are then explained.
