True Variable-Depth Milling of Nickel-Based Alloy In-718

Abstract

investigated deeply by researchers, notch wear has been somewhat overlooked, despite the fact that it hasan important role in the tool replacement decision. Notch wear happens due to impact forces at the depthof cut particularly during intermittent cutting. To avoid frequent tool change decisions, varying the depthof cut constantly during machining has been proposed as an alternative. In this study, milling experimentswere conducted on the nickel-based alloy IN-718 where the depth of cut was varied throughout the cut.Results show favorable findings towards eliminating notch wear without compromising from machiningefficiency
