Investigation into material removal influenced by edge effect in polishing

摘要: Edge effect is unavoidable in polishing process when the pad passes by workpiece edge, which influences entire form accuracy of free-form surfaces optical components computer-controlled polishing, or even reduces their effective aperture. This article focuses on a theoretical and experimental investigation into material removal influenced edge for along certain path. The contact pressure distribution models are summarized modified four representative models: linear model, skin model divided adopted to calculate profiles orthogonal straight curved path, this article. So, built tool path instead single point. And experiments carried out choose most suitable according comparison e...
