Tactile Measurement Technology
How does tactile measurement work?
Tactile measurement technology enables highly precise, contact-based measurement of objects. This process uses probes that touch the surface of the component and record measurement points. Using specialized software, these measurement points are then used to generate various 3D elements that are used for measurement purposes, such as calculating diameters, areas, curves, and much more.
What measurement tasks are performed?
Tactile measurement technology is used in industrial metrology for a wide range of measurement tasks. These include, for example, determining shape deviations of free-form surfaces and measuring dimensions such as diameters, distances, and angles. Tactile measurement can also be used to inspect surface finish, roughness, and contours. As a provider of 3D measurement services, we offer reliable and precise execution of various measurement tasks using tactile measurement technology.
- Measuring Control Geometry
- Measuring Free-Form Surfaces (Measuring Against a CAD Data Set)
- Initial sample submissions with a test report in accordance with VDA
- Routine measurements
- Aptitude Tests
- Determination of Measurement Uncertainty
- Support for Machine and Labor Shortages
Accredited tactile measurement to ISO/IEC 17025
We carry out tactile measurements on our WENZEL coordinate measuring machines as a testing laboratory accredited by the Swiss Accreditation Service SAS (STS 0629). The scope of accreditation covers the testing of dimensional, form and position tolerances according to SN EN ISO 1101 on workpieces made of metal and plastic, with a measuring range of up to 800 × 1500 × 700 mm. For you, this means traceable measurement results with stated measurement uncertainty – a reliable basis for initial samples, series inspection and complaints. More about our accreditation.
When is tactile measurement the right choice?
- tight tolerances on easily accessible features such as bores, fits, distances and angles
- form and position tolerances according to the drawing, for example flatness, roundness, parallelism or position
- measurements for which an accredited inspection report is required
- comparison of freeform surfaces with the CAD data set
Internal geometries that the probe cannot reach are captured with industrial computed tomography. Which method is suitable depends on part size, properties, tolerances and the required features – a combination often makes sense. More in the article CT or tactile measurement?
What you receive
An inspection report with nominal and actual values, tolerances, an assessment of each feature and information on measurement uncertainty. The coordinate measuring machines automatically compensate for temperature to the reference temperature of 20 °C. Turnaround time is usually three to four working days.
