Controlling every stage of production is fundamental to obtaining precise, high-quality mechanical parts. To do it properly, however, a climate-controlled metrology room is needed. What is it?
Precision engineering supplies specific, custom parts to meet the needs of every industry. From the technical drawing to the choice of material and the machining itself, every stage must be carefully monitored. Inspection of precision components must rely above all on a climate-controlled metrology room.
What is metrology?
To understand what a climate-controlled metrology room is, we need to take a step back and look at metrology as applied to precision engineering. Metrology is the discipline concerned with measurement procedures and their applications in every field, including precision engineering. This science arose from the need for uniform, reproducible methods to determine a “quantity” of an object or substance precisely and unambiguously.
The need for certain, precise measurements in precision engineering led to the creation of the climate-controlled metrology room. Essentially, it is an environment with set, controlled and constant temperature and humidity.
To qualify as such under the international standard ISO/IEC 17025, the room must be kept at 20 degrees and avoid variations of any kind.
Climate-controlled metrology room: features and benefits
Thanks to its characteristics, a climate-controlled metrology room allows a range of activities, notably the calibration of measuring instruments and dimensional inspection.
A specialised company producing precision parts with a climate-controlled metrology room can avoid any dimensional variation in materials.
Because temperature and humidity do not change in this environment, their effect on materials is eliminated. Using equipment and instruments for dimensional inspection of mechanical parts, products can be guaranteed to conform to the technical drawing. A climate-controlled metrology room also makes it possible to issue dimensional certification, meeting the needs of customers that require certified measurements (e.g. automotive or medical). T.M.G. has its own climate-controlled metrology room: see our quality control.
