【Abstract】 Cutting is an important manufacturing process of metal. The chip formation in met cutting is one of the typical deformation problems. Based on the analysis of structural characteristics of a kind of thin-wall long shells, the machining process of aluminium alloy parts were analyzed. Base on the material and property and process method, the working-principle and technical characteristic were introduced. The key steps of this technique were presented and analyzed. A manufacturing process combing turning and welding for those parts was presented. Numerous experiments prove the feasibility of this applied process.更多还原
