Dimensional inspection of high-temperature metal parts in the steel and metallurgical sector is essential to ensure the manufacture of quality products.
For this purpose, specialised instruments are used, such as LASER triangulation sensors, LASER distance meters and other instruments based on an optical measuring principle.
LASER triangulation sensors provide accurate measurements by measuring the distance between two points with an infrared or visible light source.
These devices can detect even the smallest irregularities in the shape or dimensions of a part. LASER distance meters are precise, fast instruments used to measure the distances between two points on the surface of a part. They use LASER beams to measure distances accurately without any human intervention.

Technical insights
Position measurement is also essential for producing quality metal parts for steel and metallurgical applications. By comparing the coordinates resulting from a position scan with predetermined values, position errors on the parts can be detected with an accuracy of fractions of a millimetre.
Thickness measurement
Thickness measurement is also an important factor in the dimensional inspection of metal parts. The thickness of a part can be measured using laser triangulation sensors or laser micrometers, which can measure to an accuracy of 0.001 mm without the need for contact. This ensures fast, precise measurements without the risk of damaging the part during the test. In addition, most modern instruments use computer algorithms to calculate average and point thicknesses from a single scan.
Furthermore, some position measuring systems use computer vision technology, which makes it possible to detect automatically the geometric features of complex shapes, such as holes or grooves on the surface of a part, without the need for contact.
Straightness measurement
Straightness measurement is also necessary to ensure that metal parts meet quality standards before being used in production processes or other applications. Straightness measurement involves measuring the difference between a reference line and the actual surface profile along various intervals of the length of the part under test. Today, various advanced instruments are available that allow measurements with accuracy levels down to 0.01 mm along lines up to 10 m long, without any intervention by the user during the entire process.
Width measurement is another important factor in dimensional inspection, because of its wide range of applications in various sectors such as steel production and others where accuracy is essential. While traditional methods of width measurement involve the use of tape measures or manual gauges, modern technologies allow automatic measurements that require minimal set-up time and provide significantly more accurate results than traditional methods. For example, many laser triangulation sensors are equipped with multi-point scanners capable of quickly measuring widths at several points over large areas, even at high temperatures, with outstanding accuracy.
Solutions for dimensional inspection
RODER offers complete solutions designed specifically for dimensional inspection needs when dealing with high-temperature metal parts in steel and metallurgical applications.
RODER supplies advanced equipment such as the Vision System series, with automated visual recognition algorithms that allow rapid inspections over large areas with little manpower.
Industrial dimensional inspection
The combination of the specialised instruments mentioned above helps to streamline dimensional inspection processes, improving overall levels of accuracy and efficiency. In particular, the unique features of each instrument help to reduce total testing times significantly, while providing reliable results on all types of materials, regardless of the heat treatments applied.
In addition, many modern systems are equipped with intuitive graphical user interfaces (GUIs) that allow users to set up tests easily and to monitor remotely the data obtained throughout the test.
Quality improvement
As well as improving process efficiency levels, these advanced technologies have also helped to reduce human error rates thanks to their automation capabilities. For example, powerful industrial computers now control entire dimensional inspection processes, ensuring the reliability of all tests.
Furthermore, sophisticated algorithms built into the latest models allow these machines to identify anomalies quickly in all the components tested, thus reducing potential delays during production cycles. Finally, the ability to integrate into larger network systems further improves data management capabilities, helping companies to track crucial production metrics more accurately.
Customised systems
In addition, recent advances in software development have allowed manufacturers to create customised programs designed specifically around the customer’s requirements, ensuring that every test produces optimal results every time. In particular, dedicated simulation software packages allow operators to plan test strategies in advance, helping them to determine the best courses of action well before the actual tests begin. Moreover, special analysis tools give users the ability to compare previous tests instantly with current ones through native dashboards that allow operators to achieve better results
