Estudo do processo de estampagem incremental em chapas de aço AISI 430

Abstract

This paper presents a study about physical and thermal behavior of AISI 430 steel sheets submitted to the Single Point Incremental Forming process (SPFI). In the tests were used the following resources: CNC machine center with three axes, incremental forming tools, a blank holder, lubricant oil, infrared thermometer, software CAD (Computer Aided Design) /CAM (Computer Aided Manufacturing). During the experiments, parameters such as: tool rotation, type of lubricant and temperature of the sheet during the process, were taken into account. In order to obtain a better understanding of the behavior of the AISI 430 steel in the process, procedures such as tensile testing, metallographic analysis and measurement of roughness parameters were performed before and after each SPFI test. The tests showed that the steel presents a good formability for the incremental sheet forming process.
