The 10-pass example should be fine if you're running non-notched, postcut mild steel. If the section is notched, precut, or high-strength material, you'll need more passes to achieve desired results. Additional passes allow the material to flow through the mill with less strain. Design the Layout and Roll Tooling

The Euler angle parameterization Rotations
Feb 08, 2021 The most popular representation of a rotation tensor is based on the use of three Euler angles. Early adopters include Lagrange, who used the newly defined angles in the late 1700s to parameterize the rotations of spinning tops and the Moon [1, 2], and Bryan, who used a set of Euler angles to parameterize the yaw, pitch, and roll of an airplane in the early 1900s [].
