Limitations of Optical Measurement in Industrial Inspection
Optical measurement systems are widely used in industrial inspection because they provide fast, non-contact, and highly detailed measurements. Video Measuring System (VMS) are commonly applied in quality control, dimensional inspection, and manufacturing environments where repeatability and efficiency are important. However, optical measurement is not suitable for every inspection condition. Factors such as surface reflectivity, material […]
Batch Measurement vs Individual Inspection in Video Measuring Systems (VMS)
Inspection efficiency is important in manufacturing and quality control. In Video Measuring System (VMS) operation, measurements can be performed either individually or through batch inspection methods. Both approaches have advantages depending on the application, production quantity, and inspection requirements. What Is Individual Inspection? Individual inspection measures parts one at a time. Each component is positioned […]
Feature Selection in Video Measuring Systems (VMS)
Video Measuring Systems (VMS) include many measurement and analysis functions designed for different inspection tasks. However, more features do not always lead to better measurements. In many cases, selecting the correct feature for the application is more important than using every available function. Effective VMS operation focuses on obtaining meaningful, repeatable, and efficient measurements. By […]
Designing an Efficient Inspection Workflow Using Video Measuring Systems (VMS)
It is common to view a Video Measuring System (VMS) as an efficient inspection solution. In practice, however, the efficiency of inspection does not come from the system alone, but from how the workflow is designed around it. A Video Measuring System (VMS) is a powerful tool, but without a structured inspection approach, its capabilities […]
Manual vs Automatic Video Measuring Systems (VMS)
Dimensional inspection systems such as Video Measuring Systems (VMS) play a critical role in modern manufacturing by providing accurate and repeatable measurement data. However, as production demands increase, accuracy alone is no longer sufficient. The ability to perform measurements efficiently and consistently across large numbers of parts becomes equally important. While both manual and automatic […]
Statistical Process Control (SPC) Using Video Measuring Systems (VMS) and Coordinate Measurement Machines (CMM) Measurement Data
Dimensional inspection systems such as Video Measuring Systems (VMS) and Coordinate Measurement Machines (CMM) are capable of producing highly accurate and repeatable measurement data. However, collecting precise data alone does not ensure process stability or product quality. In many cases, manufacturers rely on pass/fail inspection without fully utilizing the generated measurement data. As a result, […]
Tips for Selecting the Right Measurement Equipment for Industrial Production and Quality Control
Selecting measurement equipment for production is not just a purchasing exercise. It is a process control decision. Inaccurate or unstable measurement systems can lead to false rejects, undetected defects, and unreliable quality data. As production tolerances tighten and compliance requirements increase, the impact of incorrect equipment selection becomes more severe. This article is intended for […]
Environmental Control in Precision Measurement Laboratories
Precision measurement requires more than advanced equipment and skilled operation. The surrounding environment plays a critical role in ensuring that measurements are accurate, consistent, and repeatable. Even small variations in environmental conditions can introduce errors that affect the reliability of measurement results. In precision measurement laboratories, environmental control is implemented to minimize external influences that […]
Edge Detection Techniques in Video Measurement Systems (VMS)
In Video Measurement Systems (VMS), measurement accuracy depends not only on optical resolution or system stability, but also on how precisely the system can identify the boundaries of a feature. This process, known as edge detection, is fundamental to determining dimensions such as lengths, diameters, and angles. Unlike traditional contact measurement methods, the Video Measurement […]
Thermal Expansion Effects on Video Measurement System (VMS) and Coordinate Measuring Machine (CMM) Measurement Accuracy
In precision measurement, accuracy is often assumed to depend primarily on the capability of the instrument. Systems with higher resolution, advanced sensors, and sophisticated design are expected to deliver reliable results within tight tolerances. However, even the most advanced equipment can produce inconsistent measurements if one critical factor is overlooked: temperature. Thermal effects refer to […]
Understanding Measurement Uncertainty in Video Measurement System (VMS) Inspection
When inspecting a precision component, the measured dimension is often treated as an exact value. In reality, every measurement carries a degree of uncertainty that must be considered when determining whether a part truly meets its tolerance requirements. Understanding measurement uncertainty is therefore essential for reliable dimensional inspection. This article explores the concept of measurement […]
The Science Behind Non-Contact Optical Measurement in Video Measurement Systems (VMS)
Non-contact optical measurement refers to the acquisition of dimensional and geometric data without physically touching the measured component. Instead of mechanical probes, these systems rely on controlled illumination, precision optics, and digital imaging to extract measurable information from reflected or transmitted light. As manufacturing tolerances continue to tighten and component geometries become increasingly intricate, traditional […]
Introduction to Industrial Metrology: Why Measurement Matters in Manufacturing
Modern manufacturing is built on the expectation that components will function reliably under demanding operational conditions.

To maintain dimensional accuracy throughout production, industrial metrology systems are integrated directly […]
Boosting Productivity in High-Volume Manufacturing with Automated VMS
High-volume manufacturing requires fast output, stable quality, and consistent accuracy. As production increases, even minor delays or inconsistencies in inspection can create bottlenecks and increase costs. Many factories face this challenge when relying on manual measurement tools, which are slower, operator-dependent, and difficult to scale. To solve this, manufacturers are increasingly adopting Automated Video Measurement […]
How an Automotive Supplier Reduced Defect Rates with CMM
In automotive manufacturing, even small defects in components can lead to serious issues, from assembly problems and production delays to increased costs and safety risks.
