Why metrology solutions are vital for automotive manufacturers

Displacement sensors, displacement transducers and other precision-measurement technology have already played an enormous role in the development of the automotive industry, not least in giving cars a much longer road life, and their influence is only growing. 

The standardisation of pats is integral to the successful operation of automotive production plants, in particular as the volume of automated manufacturing grows. The ability to precisely measure parts and ensure exact standards are met accurately, time after time, is critical. And it is this accuracy and repeatability that LVDT sensors and other metrology systems help provide. 

Focusing more on the standardisation of parts, the advance of automotive technology is another factor that is underscoring the indispensability of advanced engineering measurement techniques and the right metrology partner. 

As automotive innovation continues to push boundaries, so parts are becoming increasingly sensitive. The tiniest change or difference in size can have an enormous impact on the performance of components and the products of which they are a part. Accuracy, reliability and repeatability are vital – they are a principal foundation of the manufacturing process.  

 

How gauging probes are used in the automotive industry

An example of the use of measurement sensor technology in automotive production is the role that gauging probes play in ensuring the quality of cylinder heads. The very high resolution and the excellent linearity of these probes and their high data speed capabilities are critical to the accurate calculation and checking of cylinder head diameter and centre point measurements. 

Another example is the use of standard pencil probes and single-leaf flexure probes to check the dimensions of crankshafts. In an automotive manufacturing factory environment, which can be oily, humid and abrasive, this easy-to-use and low-maintenance technology quickly takes precision measurements and has the data ready for review. 

Gauging probes are also used to measure glass automotive parts. These measurements need to be precise and delicate: too much tip force on delicate surfaces can result in incorrect data and costly damage. Low-tip-force probes, such as feather-touch and ultra-feather-touch probes, are designed to overcome these challenges, avoid errors and spoiling, and deliver the high level of result accuracy required.
