Lasertube systems, our 2D or 3D laser cutting system for tubes, bars, profiles and tubes from 12 mm up to 610mm (.5" to 24-") in diameter and 18 m (60") in length, are called Lasertube systems.
How do you compensate for that? Traditionally, you are going to come down and touch the face with a sensor that marks the contact point. The tube is then rotated, and the opposite side of the tube is touched. That gives the control an idea of just how bowed the tube is. This method is accurate and can ensure those through-holes work out for the application. But keep in mind that each time a rotation of the tube occurs, the ability to deliver very high tolerances is reduced.
