Customized thermal profile for tactile measurements

‍

Another important advantage of gear measuring machines is the ability to create a customized thermal profile for tactile measurements. Temperature fluctuations can have a significant impact on the precision of measurements. It is therefore important that measuring machines are able to take these fluctuations into account.

‍

Gear measuring machines are usually equipped with advanced thermal compensation systems that can detect and automatically compensate for temperature changes. These systems can create a thermal profile of the machine and use this information to correct the measurement results accordingly. In this way, companies can be sure that their measurements remain accurate even under changing operating conditions.

‍

A customized thermal profile is particularly useful for tactile measurements where the probe is in direct contact with the measurement object. As the heat transfer between the probe and the object can influence the measurement results, the thermal profile helps to minimize such effects.
