Abstract

In the press cutting of a square pipe, the effects of cutting parameters such as the top angle of the punch, tool clearance, wall thickness, side length and cut length on the distortion of the cut section and its surface decline towards the axis are discussed. The cutting force is also measured. The horizontal change in diagonal length is kept small, while the vertical one is increased with either decreasing cut length or increasing top angle of the punch. The higher the first peak force, which appears after cutting through the top corner thickness, the larger the distortion. For smaller distortion, the top angle should be smaller, the cut length should be longer and the thickness should be larger. The surface decline is affected by the ratio of the tool clearance to the wall thickness. To decrease the decline, it is suggested that the axial force applied during cutting work should be applied by 3% of the maximum cutting force.
