Article Preview

Asymmetric plunge cutting by using grooved knife edge plate was proposed for advanced die cutting of a polycarbonate (PC) sheet. By varying the tip angle U and the tip thickness wU of knife edge in the counter plate, and combining a standard steel cutting rule of 42° center bevel blade, a cutting load response of PC sheet was investigated and also that deformation was observed by a CCD camera. Through this works, the followings were found: 1) there were two deformation modes of sheared profile. 2) The tip thickness wU was a primary factor, compared to the tip angle of U. 3) The equivalent wedge angle effect was revealed with respect to the upper/lower angles  and U, while the PC sheet was bent up by the lower knife indentation.
