3D measurement: Optical, tactile and by white light

Dimensional tests are central components in quality assurance. It is of crucial importance to ensure that the geometric condition of a component meets the requirements necessary for its later application. If there are deviations, this can lead to complications during assembly or even premature failure of the component.

In order to check components according to their drawing specifications, dimensional tests are carried out, among other things. The characteristics examined can include a variety of dimensions, including lengths, radii, and angles, as well as form and position tolerances.

The methods for checking these dimensions cover a wide spectrum, from simple gauges and calipers to high-precision coordinate measuring machines. When carrying out these tests, it is crucial to choose the appropriate measuring instrument to ensure accurate and reliable results.

The principle of 3D measurement

3D measurement is a versatile process that can be carried out from us with three different types of sensors. The first is the tactile sensor, which uses probes to touch or scan the components. The second is the optical sensor, which uses a camera to capture edges and contours. The third is the white light sensor, which is used to record surface points.

We use a fully automated coordinate measuring machine that allows software-supported evaluation. The measurement programs can be flexibly created and individually adapted to each component. The subsequent evaluation can also be individually adapted to the drawing specifications.

Before the test, it is essential to clean the components. Contaminants such as oil can affect the measurement and distort the results. Therefore, only clean samples are measured on the device. The coefficient of thermal expansion also plays a crucial role in the conformity of the components. For this reason, dimensional tests take place in a climate-controlled measuring room.

For the test, the components are firmly clamped on the machine. Then a program for measurement is created. With unchanging clamping, the same components can be measured one after the other. This ensures efficient and accurate measurement.
