Contactless and Fast Tube Measurements
The market for tube bending is becoming more and more demanding. Tube inspection is no longer simply about comparison of intersection points between straights.
HP-L delivers a high-density point cloud and also reveals shape imperfections against the CAD model by scanning the cylindrical surface of the tube. The user is able to analyse tube shape deviations on the cross-sections at any specific location of a tube.

With the HP-L laser scanner, the inspection on the CMM can be performed in automatic mode.

Measurement of Unmachined Crankshafts
In the past, unmachined crankshafts have been measured with sometimes more than 500 tactile measurement points. With the contactless solution, the HP-L laser scanner captures the shaft with the help of a specific part program, resulting in a coloured report that arrives at the customer combined with the unmachined crankshaft.

The customer now has a much broader view on the quality of its parts, as they are now able to compare results from all over the surface, not just single points. The time-saving with the HP-L laser scanner is more than 40%.

Trimmed Edges on Sheet Metal Parts
The trimmed edges of most sheet metal parts are analysed with the help of measurements made by touch probes. In a predefined distance, depending on the workpiece, the probe collects points on the edges. For larger parts, this results in an enormous amount of measurement points. 

The HP-L laser scanner only captures one single scanning-path over the edge. The points can be extracted afterwards.

In some cases, companies need to take 300 tactile measurement points, resulting in a process time of 1 hour and 10 minutes. With the HP-L laser scanner, this now takes only 15 minutes.

^{*Values are including expanded measurement uncertainty according ISO/TS 17865:2016. Measured using a manufacturer supplied sphere and plane artefact, each certified by an independent accredited lab.}

Accuracy Specification
The specification of the accuracy of the sensor complies with the standard ISO 10360-8:2013. Other standards (ISO 10360-2 or ISO 10360-5) that were occasionally used before the introduction of ISO 10360-8:2013 are now obsolete for this purpose. Their significance on the optical measurement is too low; the values thus obtained were not tailored to an optical measuring system. If desired, an individual report can be created for each HP-L sensor according to the current ISO-10360-8: 2013 standard. The measurement for creating the report is based on certified artefacts (sphere and plane). This ensures that the functionality of the sensor can be checked at any time.
