Burr Minimization in Milling: Through Proper Selection of In-Plane Exit Angle

A burr is an undesirable projection of material formed in machined parts that makes handling as well as assembly of machine parts difficult, and hence, it needs be subsequently removed or its formation needs be suppressed to allow the parts to meet specified tolerances. One way of reducing milling burr formation may be to prevent the tool from exiting the work piece. From this idea, in-plane exit angle is varied in the present work aiming at minimization of burr formation. The experimental observation is analyzed to recommend the condition when burr formation becomes negligible, or eliminated, thereby increasing productivity as the need of deburring will be either not required, or, required to a very less extent.
