Large measurement range
The measurement range of the probe system is a critical parameter for the control of the CMM: after a probe trigger has been detected, the CMM axes should reach a standstill within the measuring range of the probe system. If this is the case, simply adding the measured probe deflection to the position measurements from the machine axes will yield the measurement point coordinates. The measurement range of the new probe system is more than 10 µm in all directions.

Probe tip size
The long-term stability of the probe system has been optimized by applying low-expansion materials. The complete probe body and the elastic suspension are made from invar®. The stylus is made from tungsten carbide. In addition, the probe system is assembled from only a minimum number of parts, without adhesives or other potentially instable assembly techniques.

Low replacement costs
Products may have small features, such as narrow ridges or small holes, which cannot be measured with a large probe tip. Reducing the probe tip size greatly increases the measurable area of such work pieces. For this probe system, spherical ruby tips with radii between 0.08 and 0.25 mm can be applied.
IBS Precision Engineering is currently developing a miniaturized version of the Triskelion probe system, which has a spherical tip with a radius of only 36 μm.
