A Measure of Optimization of Technological Parameters to Improve the Formability of Aluminum Sheet a 1050 H14 by SPIF Technology

Abstract:

The objective of this paper is to select a set of technological forming parameters including vertical feed Δz, feeding rate of V_xy of the tool (a kind of pestle but no-cutting edges), the diameter of tool D and the revolutions per minute of tool n to achieve the highest forming ability of aluminum sheet A1050 H14 (according to JIS G3101Japanese standard) when forming metal sheet by Single Point Incremental Forming Technology-SPIF. The content of the article consists of 3 processes: Pre-design of experiment (Pre-DOE) to select of a set of reasonable limited parameters when forming aluminum sheet A1050 H14 models when forming on the existent specialized SPIF machine in the National Key Laboratory of Digital Control and System Engineering laboratory (DCSELAB); Performing aluminum sheet A1050 H14 models on the Pre-DOE to obtain the forming angle values; Evaluating the experimental results by analysis of variance; Setting up the regression equation of the angle of deformability with influence parameters; Optimization the regression equation to select an optimal set of forming parameters to gain the highest deformability of aluminum sheet A1050 H14.
