Comparison of Measurement Methods to Acquire the Steel Tubes Characteristics

Abstract:

The main paper idea was compared three methods (Contact CenterMax and contactless ATOS TripleScan II, Metrotom 1500) for data acquisition to the output characteristics of steel drawing tubes. Outer and internal diameters, eccentricity and ovality were measured. Steel tubes produced by drawing should accomplish shape and dimensional characteristics. These can be measured by various contact and contactless methods. Each of these methods have advantages and disadvantages. The computed tomography advantages are, that we obtain both outer and inner tube shapes. Output is a 3D model from which you can get the elements to evaluate the characteristics. The data acquisition is limited by wall thickness and material density and that is disadvantage. The 3D scanner advantages are, that we obtain outer tube shapes with different diameters and wall thickness regardless of material density. Output is a 3D model. Problem is to obtain data about complex internal shape limited by tube length and diameter and that is the disadvantage. The advantage of acquiring data by contact method is that we obtain both external and internal tube shape, without thickness wall, diameter or material density limitation. The disadvantage is that we don´t obtain a 3D model of tube, but only a spot-scanned elements.
