Summary

Experiments are described on the indenting and cutting of round wires between 0.063 in. and 0.625 in. diameter of copper, galvanised and straight drawn medium carbon steel, and a special steel with, wedge shaped tools, to investigate the basic mechanics of the operation. Considerable use is made of some theoretically well analysed and analogous cases in the plane-strain cutting of strip and experimental evidence of qualitative agreement is presented. The investigation was carried out to determine the effect on the greatest load required to severe material, of wedge tool angle, of a flat on the end of the wedge, wire diameter and material properties; in particular the logarithm of the greatest cutting load is shown to be directly proportional to the logarithm of the wire diameter. The paper concludes with observations on the physical action and consequences of cutting.
