Knowledge from the field of coordinate measuring technology

The coordinate metrology knowledge area answers questions about initial sample test reports, component inspection, and accredited calibrations of your prismatic, conical, and spherical workpieces.

What is an initital sample inspection report (ISIR)?

Initial sample test reports document the results from the testing of specified criteria on an "initial sample". The ISIR is thus an important part of the sampling process and establishes the target and actual values. Before series production of a product starts, it must be produced under realistic series production conditions and submitted for testing. The initial sample test report provides proof that products are suitable for series production and meet the quality requirements.  

In addition to the actual dimension determination within the ISIR, roughness measurements (Rz, Ra, Ra max., Rmr, ....) and contour measurements are also carried out, among others.  

Is an accredited calibration possible for prismatic, conical and spherical workpieces?

With our accreditations we have the possibility to measure your components, special test equipment or special workpieces accredited to and to issue a calibration certificate. With a maximum measuring range up to 3 m, even large components can be measured ideally. Here you can find our certificate.

What is component testing?

This term can be used in many ways, we as inspection service provider use this term when creating inspection reports. In addition to an exact determination of the actual dimensions also the form and position tolerances of your workpiece (component) are recorded and evaluated in an inspection report.  

Which gear measurement service can Testo Industrial Services perform? 

The measurement of gears requires a high level of know-how and is very versatile. Different gear characteristics are measured and checked: Profile angle, profile shape, flank angle, flank shape, single pitch and sum pitch deviation of left and right flank, tip and root circle diameter, runout deviations and much more.  

The following gears can be measured, among others: Cylindrical gear, spur gear, bevel gear, worm, racks, internal and external gears, gear gauges, various unknown gears and much more.  

Which contract measurement/order measurement does Testo Industrial Services offer? 

As a measurement service provider, we check the geometric product specification (dimension, shape and position) with the highest accuracy, even for large quantities. Here, we tactilely measure your individual components such as housing elements, clamping devices, assembly measurements, free-form surfaces, production parts, machined parts or any special geometries on our coordinate measuring machines. We use the measuring software Hexagon Quindos/Zeiss Calypso. For optical measurements we use our strip light projector/CT-Scan.
