Description
Summary:Burr is observed on a machined job attached to its edge. Problem is experienced due to the presence of burr in the production line affecting product quality and causing possible injury to an operator, and hence, a strategy for prevention or minimization of burr formation needs to be adopted. Usually, deburring is done to eliminate burrs in industry incurring additional cost. To tackle this problem, many investigations were made in the past on formation of burr and its minimization. The aim of the present work is to find out the condition to suppress burr formation effectively during face milling of 45C8 steel specimens, which are widely used in Indian Railways. First, in-plane exit angle is varied, and it shows that an in-plane exit angle of 30° reduces burr height remarkably. Next, with the provision of 15° exit edge bevel, it is noted that burr size can be reduced effectively to a negligible value by keeping an in-plane exit angle of 60°.
