Numerical and Experimental Approach for Incremental Thread Rolling Process of Micro-Sized Screws

Abstract:

In this paper, finite element analyses of thread rolling process for the micro-sized screw with the diameter of 800 μm and the thread pitch of 200 μm are firstly carried out. For the finite element analysis of the thread rolling process, hardening behavior of SUS has been estimated by the compression and tensile tests. And then, process design has been conducted with the aid of simulations and the prototype of the micro screw finally has been fabricated. In order to verify the CAE based process design for micro-sized screws, the deformed shape and dimensions obtained from the CAE are compared with those from the experiment. The deformed shapes of the pitch part and the top part of threads can be demonstrated the feature of experimental result.
