Abstract
Sheet metal cutting is a general metal forming process. A new cutting method has been invented for sheet metal by the authors. It has been named the MM-shearing method. There are several advantages in the method, for example small cutting force, beautiful cutting surface and no burrs on the cut surface. Moreover, the equipment used in the method is inexpensive. However, there are some important parameters to consider in the MM-shearing method, such as tool angle, clearance between the tool and die, sheet thickness, and cutting speed. In this paper, a series of experiments was carried out to examine the suitable clearance. The experimental material is 1100 aluminum sheet (Japanese Industrial Standard). The cutting force, ratio of sheared and fractured surfaces, inclination angle, burr height, roughness, and Vickers hardness of the cutting surface are examined corresponding to the clearance change. The principle and characteristics of the MM-shearing method are made clear in this paper in terms of the clearance between the tool and die.
