The data above applies for test conditions as follows:

  • Stylus length 50 mm (1.97 in)
  • Stylus velocity 240 mm / min (1.57 ft / min)
* Test performed on a CMM specification U3 = 0.48 μm + L / 1000

3D measuring performance

To standard ASME B89.4.1 – 1997 for point to point measurement.

Typically, the 3D measuring performance (spherical characteristic) is better than 2 μm. This means that no matter from which direction the probe triggers, the maximum error will be less than 2 μm when standard qualification techniques have been employed using styli up to 50 mm long.

The 3D measuring performance of the probe considers the following sources of probe error:

  • Unidirectional repeatability
  • XYZ pretravel variation
  • Stylus ball sphericity
  

The table below only applies to TP7M with the additional styli:

Typical performance data for TP7M probe

The following information provides examples of the expected measuring performance of the TP7M when using M2, M3 and M4 styli in accordance with the stylus selection guidelines given earlier in this document.

In all cases, the ‘contour' lines show probe performance figures using straight or right-angled stylus configurations.

For the configuration shown, where M2-M3-M4 adaptors and M2 styli are used, the expected measuring performance from the probing system would be within ± 1.5 μm.
