Abstract

Accuracy of machined components is one of the most critical considerations for any manufacturer. One of the challenging difficult areas for manufacturer is the production of monolithic component that is usually associated with aerospace industries. This monolithic component consists of several thin-wall rib and flange sections that need to be machined. Due to the large area and low rigidity of monolithic component, the thin-walled are always machined using numerical control (NC) end milling process. However, owing to various reasons in the machining process, the thin-walled features are very easy to deform under the cutting force which will influence the accuracy and quality. This report investigates the machining performance using the step strategy for machining thin-wall low rigidity component. Four different step strategies namely waterline-step, overlapping-step, three wise-steps and 4-to-1 rule method are investigated by evaluating their machining performance on machining the thin-wall component made of aluminum alloy.
