Experimental Researches Regarding Strain Measurement of Incrementally Formed Sheet Metal Parts Done Using an Industrial Robot

Abstract

This paper aims to provide results regarding the measurement of the strains in the material of sheet metal parts which have been incrementally formed. The incremental forming of the steel sheets has been performed with the aid of a KUKA KR 6 industrial robot on a specially constructed stand, and the measurement of the strains has been done using ARAMIS optical measurement system. The trajectory of the forming punch which is attached to the robot was designed using CATIA V5 and the movements of the robot were designed and simulated in DELMIA software. DELMIA generated the program code needed for the robot to execute the desired movements in order to form the sheet metal parts.
