What are styli and what are they used for?
Touch probes are special tools that are used in measurement technology. They are used to carry out precise measurements of workpieces or components.
The measuring probe insert consists of a probe that is connected to a sensor unit. This probe is placed on the workpiece to be measured and generates a signal when it comes into contact with the workpiece. The signal is then recorded by the sensor unit and forwarded to a measuring device that displays the measured values.
Touch probes are used in various areas, such as quality assurance, production or research. They enable precise measurements of dimensions, shapes, surface quality and other characteristics of workpieces. This allows dimensional deviations or errors to be identified and corrected in order to improve product quality.

How do touch probes work and which technologies are used?
Touch probes are special tools used in metrology to carry out precise measurements on workpieces. They are used in combination with measuring machines or coordinate measuring machines.
The function of a touch probe is based on the principle of tactile measurement. The probe is placed on the workpiece and generates an electrical pulse by applying pressure. This pulse is recorded by the measuring system and converted into a measured variable, such as length, height or angle. The accuracy of the measurement depends on the precision of the measuring probe and the measuring machine.
There are different types of styli that are suitable for different applications. For example, there are styli with a ball head, which are ideal for roundness measurements, or styli with interchangeable probe tips that can be adapted to suit the measuring task.
There are various approaches with regard to the technologies used for touch probe applications. A frequently used technology is the mechanical measuring button, where the button is pressed mechanically and generates an electrical pulse. There are also optical probes that work with light and can measure the height or surface quality of a workpiece. Other technologies include electromagnetic probes, which work using magnetic fields, and piezoelectric probes, which are based on the piezoelectric effect.
The choice of technology depends on the requirements of the measuring task, such as the required accuracy, the measuring range and the ambient conditions. Touch probes are widely used in industrial production and are used in various industries such as automotive, aerospace, medical technology and electronics.

How accurate and precise are styli and what tolerances can they achieve?
As a rule, styli are very precise and can achieve high tolerances. However, these tolerances depend on various factors, such as the type of probe used, the measuring method and the accuracy of the measuring technology used.
As a rule, styli can achieve an accuracy of a few micrometers. This means that they are able to maintain tolerances in the range of a few micrometers. In some cases, styli can be even more precise, achieving sub-micrometer accuracy.
However, it is important to note that the actual accuracy of a stylus depends on various factors and can be affected by various influences in practice. These include, for example, thermal influences, mechanical loads or signs of wear.
To ensure the accuracy of a touch probe, it is therefore important to use the correct measuring methods and techniques and to check and calibrate the measurements regularly.

What factors influence the accuracy and reliability of measurements with styli?
There are various factors that can influence the accuracy and reliability of measurements with styli:
1. Quality of the stylus: The quality of the stylus itself plays an important role. A high-quality probe insert with low manufacturing tolerance and high repeat accuracy can lead to more precise measurement results.
2. Calibration: Regular calibration of the stylus is important to ensure accurate measurement. A probe insert that has not been calibrated can lead to incorrect measurement results.
3. Environmental influences: The environment in which the measurement takes place can influence the accuracy. Factors such as temperature, humidity, vibrations and magnetic interference can falsify the measurement results.
4. Alignment and contact pressure: The correct alignment of the stylus and the correct contact pressure on the workpiece are crucial for accurate measurements. Incorrect alignment or excessive contact pressure can lead to measurement errors.
5. Measuring environment: The type of surface of the workpiece can also influence the measuring accuracy. Uneven or rough surfaces can lead to inaccurate measurement results.
6. Operating error: Operating errors can also lead to inaccurate measurements. Careful handling of the probe insert and correct operation are therefore important in order to achieve accurate measurement results.
It is important to consider all these factors and take appropriate measures to ensure the accuracy and reliability of measurements with styli.

How are styli calibrated and maintained to ensure their accuracy?
Styli are usually calibrated and maintained regularly to ensure that they provide an accurate measurement. The exact procedure may vary depending on the type of stylus, but generally involves the following steps:
1. Calibration: The stylus is checked using a calibrated reference standard. The deviation of the probe insert from the known measured variable is measured and documented. This can be done either by using testing machines or by comparison with other calibrated styli.
2. adaptation: If deviations are detected during calibration, the stylus can be adjusted to improve accuracy. This can be done, for example, by adjusting zero points or replacing defective parts.
3. Maintenance: Probe inserts must be serviced regularly to ensure that they function properly. This can include cleaning dirt, lubricating moving parts or replacing wearing parts.
4. Documentation: All calibration and maintenance activities should be documented in order to have proof of the accuracy of the probe application. This can take the form of calibration certificates, maintenance logs or other records.
It is important to note that the exact calibration and maintenance method may vary from manufacturer to manufacturer. It is therefore advisable to follow the manufacturer's specific instructions to ensure the accuracy of the stylus.
