Abstract: Pockets are widely applied in the design of the aircraft structural parts. For achieving aggressive weight targets, pockets are always designed by thin walls and webs. When machining a pocket, the web is created at the face of the end mill, as opposed to ribs, which are created at the periphery of the end mill. However, difficulty exists for control the thickness tolerance when machining these thin-webs. In this paper, the on the machine measurement technology is adopted to help control the thickness accuracy of thin webs. A typical part is taken to illustrate the proposed method and test results show that the proposed method efficiently improves the machining accuracy of thin webs.

Abstract: The existent studies on the milling of the thin-web components are reviewed first, then the cutter selection strategies are discussed theoretically based on the mechanistic model of the milling cutter, and several experiments are carried out to verify the theoretical analysis. At last, the conclusions are given on the cutter selection strategy in the milling of the thin-web components.
