A Measure of Optimization of Technological Parameters to Improve the Formability of Stainless Steel Sheet SUS 304 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 Vxy 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 stainless steel sheet SUS304 (according to JIS Japanese 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 SUS304 stainless steel models when forming on the existent specialist SPIF machine in the National Key Laboratory of Digital Control and System Engineering laboratory (DCSELAB); Performing SUS304 models on the Pre-DOE to obtain the forming angle values; Evaluating the experimental results by Analyzing of the 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 stainless steel sheet SUS304.
