Abstract: A method of orbital shearing of elongated stock such as tube stock comprises passing the stock through aligned dies, then causing relative lateral displacement, arcuate or linear, between the axes of dies, and causing a relative orbital movement between one die and the stock held in the other die. The lateral movement causes partial shearing, which is propagated around the stock by the orbital movement. One die may be fixed, while the other performs both the lateral and then the orbital movement. The stock may be rotated, in which case the moving die only has to move laterally to achieve the orbital movement as well.
