Improvement of deep drawability by using punch surfaces withmicroridges Because of product miniaturization, demand for cups created by deep drawing has increased. However,because thin sheet materials exhibit poor deep drawing formability, using deep drawing on micro/mesocups is rather difficult. In this study, punch surfaces with microridges were used to enhance deep drawingformability. The concept was based on the observation that punch surfaces with microridges near thepunch nose could disperse the drawing force of punches on sheet materials and delay the cracking of sheetmaterials. In this study, cylindrical cups composed of copper alloy were used. First, punch surfaces withmicroridges were designed and the Deform 2D software was used for analyzing the formability of deepdrawing by using punch surfaces with and without microridges. Second, drawing dies were designedand produced, and an experiment was conducted to verify the results of the analysis. The study resu ...<br clear="both">
