What is the process of displacing air between gage blocks for accurate measurements called?

The process of displacing air between gage blocks for accurate measurements is called wringing. This technique ensures that two gage blocks stick together without air gaps, allowing for precise and consistent measurement of their combined length. Wringing involves a combination of slight twisting and lateral movement to create a tight bond due to atmospheric pressure and molecular attraction, enabling accurate dimensional comparisons.

This method is critical in precision metrology, as even tiny air spaces can lead to measurement errors. By understanding the wringing process, machinists and metrologists can maintain the integrity of measurements and ensure that their setups are reliable for manufacturing and quality control purposes. Other terms such as calibrating, sorting, or aligning do not directly relate to the specific action of removing air from between gage blocks in this context.
