Calotte Measurement

In order to increase durability and protect against wear and tear, tools and machine components are coated with special materials. Various coating processes are used to apply one or more layers, with a thickness of one to several micrometers, to the base material. At the end of the coating process, quality is controlled by measuring the thickness of layers as described in the DIN V ENV 1071 standard. To prepare the samples, a steel ball with a defined diameter grinds a calotte-shaped hollow into the sample.

The Calotte Grinding Measurement module is integrated directly into AxioVision, thereby enhancing its functionality to include an application for determining the thickness of layers in accordance with the calotte grinding technique.

• Flexible measurement of coated samples and components
• Automatic calculation of the layer thickness
• Easy generation of reports

Besides the option of dragging out a circle, starting from the outside edge, it is also possible to reconstruct a circle by clicking on any number of points around its edge. The precise positioning of the circle is supported by a freely movable magnifier. Not only can you measure circular indentations, but also the elliptical indentations that occur in the case of cylindrical components.

The sample data, together with the measurement results, are overlaid onto the calotte grinding image in the form of coloured annotations.The colour and font size of these annotations can be adjusted individually. All the data displayed is saved both in the image and in a file. A report containing the image, measurement results and sample information can be generated automatically.
