Abstract:Thinwalled parts mainly refer to parts with wall thickness less than 2mm，because of its high specific strength，relatively light weight and other advantages，are widely used in aerospace，electronics，mold and other industrial fields.Through the analysis and demonstration of the processing method for aluminum alloy doublesided thinwall frame web，the method of dangling machining for thin wall parts is described from the aspects of the design of process plan，the reasonable selection of cutting parameters，the selection of cutting tools and the choice of machining and clamping methods.The method provides a reference for solving similar problems.
