Abstract

   A desk-top type of forming machine was developed for single-point incremental micro forming, which did not require any die and any backing plate. Single point tools with round tips 5-100 μm in radius were used for micro forming. Forming conditions, that is, tool rotational speed, in-plane feed speed and stepwise axial feed were optimized to maximize the forming limit or elongation of thin foils. As a result, blank sheets of aluminum foil 12 μm thick was able to elongate by 128% and 74%, for forming miniature pyramids with bases of 1 mm x 1 mm and 100 μm x 100 μm, respectively. Miniature letters were also formed successfully on aluminum foil 6.5 μm thick. [This abstract is not included in the PDF]<br>
