Abstract
This paper describes a pushing-cut process of stacked polycarbonate (PC) sheets. In this work, the cutting line force of a 30°/90° facet blade on the upper PC work sheet and the deformation of its PC work sheet were simulated by an FEM code (MSC.MARC-2005R3) in order to reveal the effect of stacked structure on deformation flow of the PC work sheet mounted on a PC underlay. The deformation profile of the work sheet was observed with respect to indentation of the blade by varying the friction coefficients of the work sheet with the blade and that with the underlay, and also the anaphase work-hardening effect of the PC sheet was discussed for estimation of the final cutting stage.
