Abstract
Burr formation similar to chip genesis is a common caution in conventional metal cutting operations in which material removal by direct tool-workpiece contact cause chip generation, variation in hole quality and post cutting finishing. In the present work, effects of various process parameters on burr type, entry, exit burr heights, roundness and diametral error obtained while drilling aluminium alloy 6082 has been investigated. Equations to predict the burr heights to be obtained for different values of machining parameters were also formulated such that a trade-off between MRR and deburring costs can be drawn for subsequent stages of machining.
