Influence of ultrasound on forming force in thin sheetmetal microforming using molten plastic as flexible punch

In this paper, a measuring force method was proposed for a special ultrasonic microforming method -- Micro Ultrasonic thin Sheetmetal Forming using molten plastic as flexible punch (short as Micro-USF), and the unique force change law in Micro-USF was observed. Using a flexible punch of the methyl s...
