Initial situation:

Planarity measurement for gasket surface on casted aluminum plates

Client is in automotive industry and needs to validate the straightness (planarity measurement) of the casted aluminum plate. Client’s tolerance is in the range of 0.01 mm. Gasket surfaces can be exposed to high pressures of gas or oil. Surface imperfections are vital for gasket surfaces since can cause slip and leak. Therefore client needs to be sure that it has surfaces to be within the tolerances.

Particular challenges

Gasket surfaces can belong to gearboxes or engine oil pans of a car so they have to be planar. Manual inspection of such features is not feasible. The parts have to be measured in a very short time and the measurement process has to be robust and must detect all parts out of specs.

Quelltech solution

Contactless Quelltech Q6-C15-45 Laser product will perform the planarity measurement with a high repeatability and velocity. The Quelltech Laser Line scanner produces 3D point cloud of the surface and software will compare the data with a tolerance channel to discriminate the units which are out of spec.  Software indicates regions which are violating tolerance level so this region can be worked upon or the part scrapped.

Benefits for the client

Thanks to Quelltech`s high resolution laser line scanners, the quality requirements for planarity measurement can be satisfied and the rejection rate can significantly be dropped. A 100% inline inspection with high process robustness ensures the desired quality level.
