In today’s manufacturing landscape, quality control is more critical than ever. Whether producing engine components, aerospace parts, or medical devices, precision is non-negotiable. One of the key tools in maintaining that precision is the Coordinate Measuring Machine (CMM). But not all CMMs are created equal—accuracy plays a defining role in how well a CMM can support your quality assurance process.

Let’s break down what CMM accuracy really means, what affects it, and how to make sure your equipment lives up to your quality expectations.

What Is CMM Accuracy?

CMM accuracy measures how closely the machine’s results match the true dimensions of a part. It’s commonly evaluated by two key indicators:

  • Volumetric Length Measuring Uncertainty (E)
  • Probing Uncertainty (R)

These are clearly defined in international standard ISO 10360-2 and its Chinese equivalent GB/T 16857.2-2006.

According to GB/T 16857.2-2006 (Coordinate Measuring Machines—Part 2: Performance Evaluation by Length Measurement), accuracy evaluation involves:

  • Measuring known lengths at different positions and directions within the machine’s volume.
  • Ensuring that all measured values fall within the maximum permissible error (MPE) stated by the manufacturer.
  • Using certified calibration tools like step gauges or gauge blocks to verify linear dimensions.
  • Assessing probing uncertainty by measuring a calibrated sphere at 25 evenly spaced points and calculating the deviation range.

These definitions align closely with ISO 10360-2 and provide a rigorous and standardized method to compare CMMs across different brands and countries.

FUTURE Bridge CMM

Key Factors That Affect CMM Accuracy

  1. Environmental Conditions: Temperature fluctuations, humidity, and vibration can all distort measurement results. Even clean air or nearby machinery can impact the CMM’s performance.
  2. Machine Design and Build: The structural design—whether bridge-type, gantry, or cantilever—affects stability and stiffness. Lightweight materials and air bearings help reduce friction and increase precision.
  3. Probe Systems and Calibration: The type of probe (contact vs. optical), its extensions, and how often it is calibrated all impact accuracy. Long or angled probe setups tend to reduce reliability.
  4. Software Algorithms: Smart algorithms help compensate for small machine errors, align coordinate systems, and ensure clean data capture during complex measurements.
  5. Operator Skill and Setup: Human error matters too. Part alignment, clamping, and probing technique all influence the final result.
  6. Accuracy vs. Repeatability: What’s the Difference?When evaluating a coordinate measuring machine (CMM), two terms often come up: accuracy and repeatability. While they’re related, they measure different aspects of performance and should not be confused.

Accuracy refers to how closely a CMM’s measurement aligns with the true, actual dimension of the part. It reflects the degree of correctness in a single measurement. On the other hand, repeatability—also known as measurement consistency—describes the machine’s ability to produce the same measurement result when the same part is measured multiple times under identical conditions.

For instance, a CMM might consistently report a measurement that is 5 microns off the true value. In this case, the repeatability is high, but the accuracy is low. Conversely, if a CMM returns results that fluctuate between ±5 microns around the true value, it is relatively accurate, but not highly repeatable.

Both characteristics are essential. High accuracy ensures that you are inspecting to the correct value, while high repeatability guarantees consistent measurement results, critical for maintaining process control. Ideally, a well-calibrated CMM should offer both. When selecting or evaluating a CMM, always consider both specifications to ensure reliable quality control over time.

How to Improve CMM Accuracy

  • Control the Environment: Install your CMM in a climate-controlled room with minimal vibration. Follow the manufacturer’s specified temperature range for optimal performance.
  • Calibrate Regularly: Use certified artifacts like step gauges or spheres to verify both linear and probing uncertainties. Regular checks prevent drift over time.
  • Choose the Right Measuring Volume: Make sure your CMM’s X, Y, and Z axes comfortably exceed the dimensions of your largest parts—ideally double their size—to allow space for fixturing and probe movement.
  • Understand Your Tolerance-to-Uncertainty Ratio: A common rule of thumb is maintaining a 1:5 or 1:10 ratio—meaning your CMM’s measurement uncertainty should be five to ten times smaller than the part’s tolerance.
  • Use the Right Software: Don’t underestimate your software needs. If you’re measuring complex geometries or special features, make sure your software supports it.

CMM Accuracy

 Why Accuracy Matters in Real-World Applications

  •  Aerospace and Automotive: Even a micrometer of error can compromise performance or safety.
  • Medical Devices: Strict tolerances ensure functionality and regulatory compliance.
  • Tool & Mold Making: Accurate molds lead to accurate parts—and fewer production defects.
  • Energy & Rail: Large, heavy-duty components still demand precise fit and alignment.

No matter the industry, the ability to reliably measure within spec is what separates leading manufacturers from the rest.

Conclusion

CMM accuracy isn’t just a technical spec—it’s the foundation of quality assurance in modern manufacturing. By understanding what drives accuracy and how to manage it, you can choose the right CMM and keep your inspection process sharp and reliable.

In precision manufacturing, accuracy isn’t optional—it’s the foundation of quality. Even the smallest variation in component dimensions can lead to performance issues or product failure. While traditional tools like calipers and micrometers have long served their purpose, they’re increasingly being replaced by more advanced, automated solutions. One such solution is the Coordinate Measuring Machine (CMM), a cornerstone of modern metrology.

What Is a Coordinate Measuring Machine?

A Coordinate Measuring Machine (CMM) is a high-precision device that captures the exact dimensions of an object by identifying its geometric coordinates—length, width, and height. Using either physical contact or optical systems, the machine maps out a part’s geometry to ensure it meets specified tolerances.

There are several structural types of CMMs, including:

  • Bridge: compact and precise, ideal for moderate-sized parts
  • Cantilever: open design for easier access to components
  • Horizontal: Arm – suitable for elongated or asymmetrical parts
  • Gantry: designed for inspecting large or heavy components

Whether using tactile probes or non-contact sensors like lasers and cameras, all CMMs serve the same fundamental purpose: capturing detailed measurement data with extreme accuracy.

PRIME Bridge CMM

What Is a Coordinate Measuring Machine Used For?

CMMs are widely employed in industries where precision is non-negotiable. They are essential in quality control processes across sectors such as aerospace, automotive, electronics, and medical device manufacturing.

Different CMM designs serve specific use cases:

  • Bridge-type CMMs are well-suited for inspecting small to mid-sized components in controlled production settings.
  • Cantilever CMMs offer open-sided access, making them ideal for repetitive tasks involving compact parts.
  • Horizontal Arm models accommodate larger, awkwardly shaped items that don’t fit on standard tables.
  • Gantry CMMs are robust enough to measure very large and heavy components without needing to reposition them.
  • Regardless of the industry, CMMs ensure that every part adheres to strict dimensional requirements, helping to prevent defects and improve product consistency.

Benefits of Using Coordinate Measuring Machines

Incorporating a CMM into your production line comes with a wide range of benefits that extend beyond just accurate measurements.

  1. Precision and Consistency

CMMs offer a level of repeatable accuracy that manual methods simply can’t match. Once programmed, they measure parts the same way every time, eliminating operator variability.

2. Greater Efficiency

Automated inspections reduce manual labor and save time. Complex parts that once required hours to measure can now be analyzed in minutes without compromising accuracy.

3. Adaptability

CMM systems are compatible with a range of probes and accessories. They can also integrate with modern software for real-time data analysis and reporting, allowing for greater flexibility as production needs evolve.

4. Reduced Waste

Early detection of dimensional errors helps manufacturers avoid costly rework or scrap. This not only improves the bottom line but also supports more sustainable operations.

5. Enhanced Brand Value

Delivering consistent quality builds trust. CMMs help businesses maintain high standards and a reputation for reliability.

Loong Gantry CMM

How Does a Coordinate Measuring Machine Work?

While the specific operation may vary by model, all CMMs follow the same basic principle: the probe moves along multiple axes to collect geometric data from an object’s surface.

Here’s how the process generally works:

  1. Part Preparation: The component should first stabilize at room temperature to ensure accurate measurement.
  2. System Calibration: The machine must be calibrated using certified reference artifacts to confirm that measurements are within tolerance.
  3. Measurement: The probe—contact or non-contact—is guided to the designated features. As it touches or scans the part, it records coordinate points.
  4. Data Analysis: Measurement software processes and compares the recorded points to the CAD model or dimensional blueprint.
  5. High-end systems may use laser interferometers or other advanced technologies to boost accuracy further, particularly in demanding applications.

Main Components of a Coordinate Measuring Machine

Understanding the structure of a CMM helps in selecting the right model and maintaining its performance. Key components typically include:

  • Frame and Guideways: These determine the machine’s stability and movement precision.
  • Probes: Devices that perform the actual measurement. They can be mechanical touch probes or optical sensors.
  • Controllers: Electronics that manage axis movement and data input/output.
  • Software: The interface where users plan measurements, view results, and analyze deviations.

Each part plays a crucial role in ensuring the CMM delivers accurate and efficient measurements.

Conclusion: Why CMMs Matter

As manufacturing becomes more complex and quality standards rise, coordinate measuring machines have become indispensable. They not only boost accuracy and productivity but also support smarter, data-driven production environments.

Sheet metal square pipe fitting is an essential component with wide applications across industries. In the automotive manufacturing sector, it is a core element of vehicle body structures, and its quality directly affects the stability and safety of the entire vehicle. In the electronics and electrical fields, from computer cases to mobile phones, square pipe fitting is an indispensable component. Additionally, it plays a significant role in medical devices, self-service equipment, and many other areas. Therefore, it is necessary to ensure precise measurement of these components.

Measureing? Challenges

  • When measuring the wall thickness of small-sized sheet metal square tubing, traditional measuring tools often fail to meet the required precision, and human errors easily occur.
  • Traditional methods only provide static data and are unable to monitor the changes of the fitting sizes in real-time or detect quality issues during the production process.

Recommended Solution

1) Measurement Principle

When measuring square tubing, the operator needs to hold the portable arm and touch the probe on the surface of the measured target. By rotating and moving the elbow, the arm is able to collect coordinate data from different positions on the tubing. Then, the data will be transmitted to the control system and processed and analyzed by the software. Finally we get the required dimensions, shapes, and positions of the tubing.

2) Measurement Steps

  • Establish the Coordinate System

① Compare the workpiece with the drawings. Analyze the drawing requirements and relations between each dimension, and identify the features on the workpiece. Use the measuring arm to detect the relevant feature elements.

② Import the CAD model. After importing the CAD model, the PMT engineer will delete unnecessary components (such as cylinders, connecting blocks, valve islands, brackets, screws, etc.) according to the requirements of the CAD model, and retain the modules that need to be inspected.

③ Establish the coordinate system (usually using methods such as the center point of the plane axis, iteration, etc.). Align the measured data with the nominal data to establish the positional relationship between the measuring arm and the workpiece. This will facilitate the next steps.

  • Data Acquisition

Contact measurement with the portable measuring arm: The engineer will collect data by touching the surface of the workpiece with the ball probe of the arm and use the least squares method to best-fit the measured data parameters.

  • Data Analysis

Based on the technical requirements, we can analyze the position of holes and surfaces. In the measurement system, the shape deviations, position and other parameters of the measured object can be evaluated, and the key dimensions can be marked.

  • Report Generation

Generate a report based on the measurement results. The report should include basic information about the measured object, parameters, results, error analysis, and other relevant content.

  • Feedback of Results

Send the measurement results to relevant departments so the company can facilitate subsequent production, processing, and quality control activities.

  • Batch Inspection

Since sheet metal components are often mass-produced, it is common to conduct random sampling or batch inspection of the same product. In such cases, the creation of new workpiece command in the software can be used for repeated inspections, with no need for data editing or processing, greatly improving measurement efficiency.

Advantages of the Portable Measuring Arm in Pipe Fitting Inspection

① High Precision

The PMT portable arm employs advanced angle encoder technology, enabling high-precision measurements that meet the requirements of most industrial production and quality inspection processes.

② High Efficiency

Compared to traditional methods, the PMT measuring arm is easy to install and calibrate. Operators can quickly learn how to use the machine, an process and analyze the data through the software, reducing the workload associated with manual calculations and data handling, thereby increasing work efficiency.

③ Strong Flexibility

The PMT portable measuring arm can rotate and move flexibly, adapting to the measurement needs of square tubing of various shapes and sizes. It can also be used in complex environments.

Other Applications

In industries such as mechanical manufacturing, automotive manufacturing, and aerospace, square tubing is widely used in the production of various structural components. For large square tubing structures, such as steel structures in construction or bridge structures, the PMT measuring arm is able to perform rapid on-site inspection to ensure construction quality control.

During the research and development of square tubing, the PMT portable arm can provide precise measurements of samples to optimize the design process. It can also compare different schemes and select the optimal design for customers.

Conclusion

The PMT portable measuring arm is the ideal tool for measuring sheet metal square tubing. With its high precision, high efficiency, and strong adaptability, it meets the high demands of industrial manufacturing, provides reliable quality assurance, and plays an important role in the research and development stage, showing great value across different industries.

China’s auto exports and annual sales take the lead in the world amid the rapid development of new energy vehicles. The nation is moving steadily toward a new phase of growth for its auto industry featuring intelligence, sustainability and innovation.

Price war has become the norm since the rapid development of the market will inevitably bring fierce competition. However, the market has proved that car companies have been raising their competitiveness, and the trend has shifted from low-priced competition to applications of cutting-edge technologies, exceptional performance of products, and branding development. This will help reshape the industry.

3D measurement technology has been playing an increasingly important role in modern manufacturing. It can provide high-precision measurements for different sizes and shapes, which is of great significance for improving product quality and production efficiency. As an advanced 3D geometric measurement system, PMT ALPHA has a built-in counterbalance system which is specially designed for on-site inspection. The structure of the equipment is simple and balanced, thanks to its perfect equal arm length design, which delivers an outstanding arm-operating experience. PMT portable arm is compatible with many measurement software and widely used in manufacturing industries as follows.

 

Reverse Engineering

In scanning clay sculptures or similar kinds, the Alpha M ScanArm can quickly model with its collected data without pasting marking points, which greatly shortens the design cycle and thus improves efficiency. Here is an example from a car manufacturer who used reverse engineering to do 3D modeling of a prototype car during the process of creating a new model. It all only took two weeks, saving about 40 percent of the time compared with traditional methods.

 

 

Molds and Production Tools Inspection

Use ALPHA Arm to do regular inspection of molds and production tools, and to analyze the wear condition so repairs or replacement could be made. For example, the customer used the PMT Alpha arm on their auto parts production line to inspect the mold on a regular basis. They detected and fixed a slight wear problem in time, helping prevent production delays and cost increases caused by mold damage.

 

 

CAD Model Comparison

Using ALPHA Arm to measure 3D coordinates will help ensure the accuracy of auto parts. We can see deviations between the actual workpiece and the CAD model by comparing the measured data with the nominal data. For example, in a process of quality control of key components, the operator used the ALPHA arm to detect dimensional deviations in a batch of components, and feedback was immediately sent to the production department. It effectively helped prevent the customer from producing batches of substandard products.

 

Tool Alignment

We can make adjustments to the assembly position according to the obtained accurate data of the auto parts so as to make sure the accuracy and quality of the whole process. For example, on the assembly line of a high-end model, the application of the PMT ALPHA arm has improved the assembly accuracy by 20 percent, significantly enhancing the quality of the vehicle and customer satisfaction.
