"Dimensional Analysis - Porosity Analysis - Deviation Analysis from CAD Design"

Advanced Principles and Applications of Industrial Tomography with a Quantitative Focus

Industrial tomography utilizes advanced techniques for the non-destructive analysis of an object's internal structure by leveraging the principle of differential radiation absorption, such as X-rays or gamma rays.

This methodology relies on the unique property of materials to attenuate radiation to varying degrees, allowing for a detailed examination of the internal composition without altering the object.

Acquisition and Reconstruction Process

When an object is exposed to a radiation source and rotated, the rays pass through the object from various angles, being captured by a detector.

The attenuation of the rays, I, depends on the density, ρ, and the thickness, d, of the material traversed, following the law of exponential absorption:

where I0​ is the initial intensity of the rays before entering the object, and $$μ(ρ) is the mass attenuation coefficient, which depends on the material's density.

By collecting radiographic projections from multiple angles, it's possible to apply algorithms for filtered back projection or iterative reconstruction to calculate the three-dimensional density distribution within the object.

This process results in detailed three-dimensional images, or tomograms, revealing the internal structure.

The Basic Formula for Image Reconstruction

Computational tomography utilizes mathematical algorithms to reconstruct three-dimensional images from radiographic projections collected at different angles.

An example of a formula used in this process is the Filtered Back Projection (FBP) Reconstruction Algorithm, which can be expressed as:

where $$I(x,y) represents the intensity of the point in the reconstructed image at coordinates $$(x,y), $$p(θ,s) is the radiographic projection at an angle $$θ and a distance $$s from the rotation center, and the integral is calculated over all projection angles from $$0 to $$π radians.

Industrial Metrological Tomography

Beyond the simple identification of defects, metrological tomography goes further, combining imaging techniques with highly precise measurement methods.

It uses sophisticated image processing algorithms and advanced calibration systems, not just to visualize but also to accurately measure the dimensions and shapes of objects.

This approach is crucial in contexts where dimensional specifications and geometric conformity are essential for the functionality and performance of the product.

Consider wanting to measure the internal diameter of a small mechanical component with complex geometries.

Metrological tomography employs the concept of 3D volumetric reconstruction, where the dimension $�$D of an internal detail can be calculated through the equation:

where $$(x1​,y1​,z1​) and $$(x2​,y2​,z2​) represent the three-dimensional coordinates of the opposite points of the measured detail.

This precision is crucial for applications such as the dimensional analysis of components in high-technology sectors, where every micrometer counts.

Chapter 8: "Metrological Tomography vs. Traditional Tomography: Key Differences in Application and Purpose"

Differentiating between Metrological and Non-Metrological Tomography: In-depth Analysis of their Features and Applications

The main distinction between a metrological tomograph and a non-metrological one is intrinsic to their purpose and scope of use. Let's explore these differences in more detail:

Non-Metrological Tomography:

The non-metrological tomograph, as the name suggests, is designed for purposes beyond metrology, i.e., the science of measurements.

This type of tomography is commonly used to examine and analyze the internal structure of objects without the primary goal of providing precise dimensional measurements.

Instead, its use focuses primarily on defect detection, material analysis, and three-dimensional visualization of objects without the need for specific dimensional measurements.

The applicative flexibility of non-metrological tomographs makes them valuable tools in a wide range of sectors and applications.

From scientific research and engineering to archaeology and biological sciences, these devices are used to explore the internal structure of objects of various sizes and compositions, providing a detailed insight into their morphology and composition without the need for precise dimensional measurements.

While non-metrological tomographs are capable of detecting defects and anomalies in the structure of objects, their main goal often lies in analyzing the internal structure for purposes of research, scientific exploration, or material analysis.

In summary, the main distinction between a metrological tomograph and a non-metrological one lies in their primary intent and specific application.

While the former is aimed at providing precise measurements of the dimensions and shapes of objects, the latter focuses more on the visualization and analysis of internal structure without necessarily concentrating on dimensional accuracy.

Standards and Regulations in Metrological Tomography: Guarantees of Reliability and Precision

Metrological tomographs must adhere to a series of standards and regulations to ensure that the measurements obtained are accurate, reliable, and compliant with international metrology standards. Some of the main standards used in a metrological tomograph include:

1. ISO 10360: This standard defines the requirements for the verification of coordinate measuring machines (CMMs), including X-ray tomography machines. It provides guidelines for evaluating machine performance, including accuracy, repeatability, and linearity.

2. ISO 16742: This standard provides guidelines for assessing the performance of X-ray tomographs used for non-destructive testing. It focuses on defining calibration, verification, and result validation procedures obtained through tomography.

3. ASTM E1695: This standard, developed by the American Society for Testing and Materials (ASTM), concerns the standard practice for verifying the performance of X-ray tomography systems. It provides guidelines for verifying spatial resolution, contrast sensitivity, and measurement accuracy.

4. VDI/VDE 2630: This standard, developed by the German Association for Information Technology, Telecommunications and Electronics (VDI/VDE), concerns measurement methods for evaluating the performance of X-ray tomographs. It focuses on defining calibration, verification, and validation procedures to ensure measurement reliability.

5. NISTIR 7034: This document, published by the National Institute of Standards and Technology of the United States (NIST), provides guidelines for assessing the performance of X-ray tomography systems. It focuses on defining calibration and verification procedures to ensure that the obtained results are accurate and repeatable.

These are just some of the standards used in tomographic metrology.

It is important to note that the choice of standards often depends on the geographical region, industrial sector, and specific applications of the metrological tomograph.

However, compliance with such standards is essential to ensure the quality and reliability of measurements obtained through metrological tomography.

"MPE: The Barometer of Reliability in Measurements"

The term "MPE" stands for "Maximum Permissible Error."

When referring to "Measuring Accuracy," it is common to use the term "MPE" to indicate how much the maximum allowable error in a measurement can deviate from the true value of the measured quantity.

"Measuring Accuracy" refers to the ability of a measurement system to approach the true or accepted value of a measured quantity. This concept is essential in metrology, where the precision and reliability of measurements are crucial.

The "Maximum Permissible Error" (MPE) defines the maximum limit within which the measurement error can vary from the true value of the measured quantity without compromising the reliability of the measurement itself.

For example, considering a metrological tomograph that provides dimensional measurements of a mechanical component, the MPE will indicate the maximum error allowed relative to the actual measurements of the component.

If the MPE is, for example, ±0.05 millimeters for a particular measurement, this means that the measurement error can vary up to ±0.05 millimeters from the true value without the measurement being considered unreliable.

In summary, the MPE provides a critical parameter for evaluating the precision and reliability of measurements made by a measurement system, such as a metrological tomograph.

A lower MPE value indicates higher precision of the measurement system, while a higher MPE value indicates lower precision.

"MPE (Maximum Permissible Error) metrological verification"

In a world where clarity and precision of information are paramount, especially in the manufacturing sector of measuring instruments, how the technical capabilities of a product are communicated can make a difference in perceiving its value.

In the context of metrology, the science of measurements, there are often communicative challenges related to the interpretation and use of technical terms.

This overview aims to shed light on how, in the fervor of marketing, some of these terms can be interpreted differently, used improperly, or even exchanged, creating fertile ground for misunderstandings and misconceptions.

The crux of the matter lies in the tension between the need to communicate the qualities of a measuring instrument accurately and the desire to make this information accessible and compelling to a broad and diverse audience.

In this perspective, marketing strategies play a crucial role, shaping the perception and interpretation of technical terms in a way that is both accurate and engaging.

However, the challenge lies in maintaining technical integrity without overwhelming the consumer with complex details that could hinder understanding rather than facilitate it.

This balance requires careful navigation, where communication clarity marries with the authenticity and precision of technical information.

The manufacturing sector of measuring instruments, therefore, finds itself at a communicative crossroads: on one hand, the need to remain faithful to scientific and technical rigor, and on the other, the necessity of speaking a language that is both accurate and accessible.

Overcoming these challenges would not only help build greater trust between manufacturers and consumers but also elevate the level of understanding and appreciation of the subtle dynamics that govern the world of metrology.

Precision vs. Accuracy:

• Precision: Refers to the consistency of measurements, i.e., the ability of an instrument to provide results close to each other under repeated test conditions. It is important to note that a series of measurements can be precise without being accurate, meaning the results can be close to each other but far from the true or accepted value.

• Accuracy: Indicates how close a measurement is to the true or accepted value. An instrument is considered accurate if its measurements are close to the reference value, regardless of the repeatability or consistency of those measurements.

Improper Use of Terms:

• In the realm of marketing and product presentation of measuring instruments, the terms precision and uncertainty may be used interchangeably or inaccurately, generating confusion. This approach may be influenced by the positive perception associated with accuracy and the negative perception associated with uncertainty, leading to an optimistic presentation of a product's capabilities.

Accuracy Statements:

• Manufacturers often provide accuracy statements that should qualitatively describe the performance of a measuring instrument. These statements, however, may include quantitative values aimed at depicting the measurement capabilities of the instrument across a wide variety of conditions, although there is a trend towards standardization to make these statements more representative of actual performance.

Maximum Permissible Error (MPE):

• MPE is a key concept in defining accuracy, establishing an upper limit to the acceptable deviation for a measurement from a reference value. This limit helps ensure that the instrument is reliable for a specific measurement task, defining the maximum tolerance beyond which the precision of an instrument is considered insufficient.

Traceability and Uncertainty:

• Traceability refers to the ability to link measurements made by an instrument to national or international standards, ensuring that the results are universally recognized. Measurement uncertainty is a fundamental component of this process, providing an estimate of the expected variability around the result of a measurement. By defining an extended uncertainty, limited by the MPE, manufacturers can establish a level of confidence in the measurement capabilities of an instrument, ensuring that it is suitable for the intended purpose.

Through a comprehensive understanding of these concepts, it is possible to more accurately assess the performance of measuring instruments and the reliability of the results obtained, facilitating the selection of the most suitable tools for specific needs.
