What is Metrology in Simple Words?

In simple terms, metrology definition is the study of measurement systems. It is originated form Greek ‘metro’ which means measurements and ‘logy’ means study.

What is Metrology in Engineering?

In engineering, the metrology definition is he since of measurement results, with theoretical and experimentation determination at any uncertainty level in any field.

What is Metrology in Manufacturing?

In context of manufacturing, it refers to the quality assurance and measurement methods employed to calibrate the machines during production for measurement results with accuracy in metrology reports.

What is the Purpose of Metrology?

The purpose of metrology is to ensure accurate and precise measurement results for trading, safety and quality of life and environment. It is performed under supervision of government to ensure that the right level of credibility and reliability.

Key Concepts in Metrology

There are a few main concepts in metrology.

Tolerance

It is an acceptable change in part’s dimension. The part’s functions are important to understand before setting the tolerance. The measurement method in Metrology helps in verifying the fitness of manufactured part within its specified tolerance.

Accuracy

It refers to the close average of measured value to the reference value, say X. This shows the difference between the actual product and technical reference drawing in metrology reports.

Precision

It refers to difference of each measured value with the average of the measurement results. The standard deviation in metrology is ±2. This refers to 95% confidence in measured value within ±2 of required value.

Repeatability and Reproducibility

Repeatability refers to variation in measurements observed by a single instrument under the same condition. Reproducibility refers to entire experimentation that can be reproduced in its completeness.

What are the Three Main Areas of Metrology?

Metrology has three main areas that covers entire areas in the field of technology. These are scientific metrology, legal metrology and industrial metrology. These all concerned with measurement method, metric system and calibration to ensure the safety reliability and quality of life.

Early Metrology Practices to Modern Industrial Metrology

The basic practice of metrology is same, but the equipment and the measurement methods are evolving with the advancements. The purpose remains the same which is ensuring reliability, and verification to precise specification in manufacturing.

What is Metrology in Semiconductor Manufacturing?

Semiconductor metrology refers to the measurement system and characterization of physical, chemical features of semiconductors devices in electronic parts manufacturing. It ensures accuracy and precision in measurement of thickness, surface properties, dimension and composition of semiconductor materials.

Subfields of Metrology

There are subfields of metrology that cover all the areas from medical to engineering and technology to ensure reliability in metric systems and standards.

Scientific Metrology

It involves the development of metric systems and advancement in measurement methods. This helps in realization of measurement system and to track the quality of standard of transfer to users and consumers.

Legal Metrology

It involves the accuracy and exactness of measurement methods. This covers the areas where it has an effect on transparency of trade, health and safety, law enforcement and the influence on environment.

Industrial Metrology

This involves the employment of measurement system to manufacturing and production and the quality assurance of measurement results. This ensures the appropriateness of measurement methods, their calibrations and quality controls.

Quantum Metrology

It refers to the employment of quantum mechanics to improve the sensitivity and resolution of devices. This is related particularly to biological applications like imaging, stimulation and sensing.

Types of Metrology

The main types of metrology are scientific metrology, legal metrology and industrial metrology. But the important and common point in all these fields is the five basic elements of metrology. These are measurement methods, measurement devices, quantities and units or metric system, properties of measuring devise and measurement standards.

Metrology Tools and Equipment in Manufacturing

There are many metrology tools and devices are used in manufacturing. Some of them are explained below:

What is Metrology Equipment?

• Vernier Caliper:this is the basic tools precise tool used in any industry. Its measured depends on the employment of tool, for example different clamping pressure can show different measurement results.
• Surface Plate:it is made of granite which has extremely flat surface. It is commonly used as reference material to measure with dial indicators or height gauges.
• Dial Indicator:they are high precision and cannot measure total variance in any part. This means it provides relative measurements. If it is integrated to the lathe, it measures the deviation in diameter of part. Or it measures the surface flatness of a plate.
• Height Gauge:this is used on a flat surface to measure height of any component. This measure height precisely and remove the variance formed by human errors.

Advancements in Metrology Technologies

Integration with artificial intelligence and machine learning is the greatest evolution in metrology. This provides auto decision-making, predictive analytics, and adaptive control. This further enhances the precision and efficiency of measurement methods.

Measurement Best Practices

It is important to follow best practice in metrology to get good metrology reports and measurement results.

Calibration of Measuring Instruments

It involves the adjustment and checking of accuracy of measurement system. It ensures to provides reliable data that aligns with international standards and improves the product quality, with safety and regulation agreements.

Environmental Control in Measurement

Environmental control is the most important part to eliminate all the risks. It includes the experimentation or practice of any data collection activity must be assessed by all the physical, chemical, or biological environmental factors that can affect human health and safety.

Training and Operator Competence

It is important to ensure the complete knowledge transfer of measurement systems, metric system and laboratory practices in metrology reports to all the operators. It is important to consider the measurement uncertainty, data integrity, traceability, basic stats, and measurement assurance.

Metrology Challenges in Modern Manufacturing

Nanometrology

It involves measurement methods to address the materials properties at nano level. It is important for the development of nanotechnology and nano-enabled products.
