A new method is proposed for curvilinear slitting or cutting of thin sheet materials, in which a rolling mill and piano wires are used as a versatile cutting device and tool. Various curves can be generated at the entrance of the rolls by using a computer controlled guide which moves the piano wire in the direction of the width of a sheet. A relationship between the movement of the guide at the entrance of rools and the generated curve at the exit of rolls is derived from geometrical consideration. The effects of wire diameter d and roll gap G on the quality and dimensional accuracy of slitted products are also examined experimentally. The experimental results show that the slitting of aluminium sheet of 0.1 mm thickness can be successfully carried out by using a wire with diameter equal to or slightly larger than the thickness of sheet and by setting the roll gap G slightly larger that the wire diameter d. The quality of the edge of slitted sheet depends on the shape of wire used, but it should be emphasized that there is no burr at the slitted edge. It is also shown that not only the curvilinear slitting of sheet materials but also other value added processes such as tapered slittting and in-plane bending of a sheet with curvilinear hem can be easily achieved by this new method.

提出了一种利用轧机和钢琴丝作为多功能切割装置和工具，对薄板材料进行曲线纵切或切割的新方法。通过使用计算机控制的引导件，可以在辊的入口处产生各种曲线，该引导件在片材的宽度方向上移动钢琴线。从几何角度导出了导卫在轧辊入口处的运动与在轧辊出口处生成的曲线之间的关系。实验还研究了钢丝直径d和辊缝G对纵切产品质量和尺寸精度的影响。实验结果表明，采用直径等于或略大于板厚的金属丝，并将辊缝G设定为略大于金属丝直径d，可以成功地对0.1mm厚的铝板进行纵切。分切板的边缘质量取决于所用线材的形状，但应强调分切边缘无毛刺。它也表明，不仅板材的曲线纵切，但也可以很容易地实现其他增值过程，如锥形纵切和平面弯曲的板与曲线折边这种新方法。
