In-Line Inspection System Improves Flange Measurement Technique
Mapvision work with real-word quality control issues and solve everyday issues with visual inspection data working in close cooperation with customers. One issue some customers have had in the past is measurement of angles, such as camber and toe angles in automotive parts, and surface flatness, in for example flanges of twist beams.
Mapvision has announced the availability of a new flange measurement method has been released in production to strengthen its portfolio of in-line inspection solutions. The method enhances all the best characteristics of optical measurements and provides superior capabilities when measuring flanges with tight tolerances.
Introducing New Flange Measurement Method
Inspecting the flanges and surface flatness of high-reflecting machined surfaces with visible light may be challenging as surface quality variations and differences in the surface finishing often lead to unstable results. Some traditional methods, such as CMM, on the other hand, may work, but are too slow.
To solve the issue, Mapvision recently joined forces with one of its partners and developed a new flange measurement method that can be connected to Mapvision’s Quality Gate inspection range to achieve more accurate and stable measurement results for challenging high-precision machined surfaces.
Improved Results For Tight Tolerances
In testing, the new system has provided much better results than the alternative measurement methods such as light grids. In a pilot with twist beams with tight tolerances R&R values of under 3 for toe angles (with ±0,1° as the tolerance requirement) and under 10% for surface flatness (tolerance 0,1 mm) were achieved.

For Twist Beams, Axles, Trailing Arms…
“This new addition in our product offering will add value with its accuracy also in inspection of twist beams, axles and trailing arms, and other complex car parts where precise angle measurement is crucial” states Mapvision. “Mapvision Quality Gate can already measure hundreds of features with high accuracy and unrivalled reliability. The cycle time is less than 30 seconds. With the new flange measurement method, we believe it offers a winning combination for the inspection of demanding machined surfaces in the automotive industry.”
