Analytical approach for selection of optimal feedrate in efficient machining of complex surfaces

The present work deals with an analytical approach that can suggest feedrate variations over the contour of complex surfaces while finish machining with ball nose end mill. In selecting the feedrate, this approach considers the material removal rate (MRR) and tool life, apart from the consistent dimensional accuracy over the contour. The effectiveness of the proposed approach is demonstrated by comparing its results with those obtained with the approach proposed by Ip [1] and other criteria. Finally, the suitability of the proposed approach for efficient machining of complex surfaces is highlighted.
