Machining Burrs Formation & Deburring of Aluminium Alloys

Abstract

Machining burrs formed in various cutting operations are rationally designated by the combination of two systems of classification: (1) by cutting edge directly concerned and (2) by the mode and direction of burr formation. The size of burr is shown to be reduced by (1) reducing the undeformed chip thickness, (2) selecting the cutting conditions so as to reduce the shear strain undergone by the chip and (3) designing the tool and workpiece geometry so as to strengthen the edge of workpiece and also to turn the direction of cutting force toward the workpiece.
