Abstract
This paper reports on an experimental investigation of the guillotining of aluminum alloy 5005. The effects of clearance and blade sharpness on performance of the guillotining process are investigated and analyzed. Four parameters are measured in the plastic deformation and fracture zones: rollover, burnish, fracture, and the burr height. It is shown that the burnish decreases as the clearance increases, and the burnish is always higher for the relatively dull blades than for sharp blades. On the other hand, fracture behavior is opposite to that of the burnish. Burr height increases as the clearance increases and as the blade gets duller.
