Optimal tool orientation in 3 + 2-axis machining considering machine kinematics

In 5-axis machining, the initial orientation and position of the part in the fixture on the machine table are chosen to avoid collisions and to ensure that axes ranges are respected. However, kinematics of the machine is rarely considered for…
