Influence of Different Parameters towards Milling Burr Minimization at Wet Condition

Undesirable burrs are created in most of the machining processes. A burr is a plastically deformed material that remains attached at the workpiece edges after machining, and must be removed for making the parts to function effectively. The main objective of the present work is to explore the suitable condition to obtain minimum or negligible burr around the edge of a machined product at wet condition. In this work, experiments have been carried out on a vertical axis CNC milling machine to perform face milling on aluminium alloy (Alloy-4600M) blocks with single inserted coated carbide tool on a 54 mm diameter cutter for observing the nature of burr formation.
