Stratistics

The trend graph displays the regular trend of the measured values, such as the monotonic and periodic change of the measured values, which can be used for monitoring the abnormality of the production process of producing equipment. Reflecting the status and distribution of fluctuations in product quality, the histogram can intuitively expose information about the quality situation in producing process, which can be used to predict product quality and failure rate.
Through quality diagnosis and analysis with statistical methods, SPC can monitor the product quality and changing trend of the producing process. With SPC we can find the preventive solution in the producing process, so that the subsequent inspection and repair are reduced. Consequently, the producing process control and product quality improvement are achieved.

Video Measuring Machine (VMMs): Precision Measurement in the Digital Age

Video Measuring Machine commonly referred to as VMMs, are advanced metrology devices used for precise and automated measurement of complex parts and components. These machines combine optical and video technology with software-driven analysis to provide highly accurate and repeatable measurements. In this comprehensive guide, we will explore the world of Video Measuring Machines, their working principles, applications, advantages, and their pivotal role in modern manufacturing and quality control processes.

Introduction to Video Measuring Machines

In today’s manufacturing landscape, precision is paramount. Components used in industries like aerospace, automotive, medical, and electronics require extremely accurate measurements to ensure quality, performance, and safety. Video Measuring Machines have emerged as a vital tool for meeting these stringent measurement demands.

A VMM is a non-contact measurement system that relies on optical and video technology to capture detailed images of a part and then uses sophisticated software to analyze these images and determine various measurement parameters such as dimensions, angles, and positions. The key components of a Video Measuring Machine typically include a high-resolution camera, precise stages for positioning, and powerful measurement software.

Working Principles of Video Measuring Machines

The fundamental working principles of VMMs can be summarized as follows:

Image Capture: The first step involves capturing images of the part or component under inspection. The VMM is equipped with high-resolution cameras, often with zoom capabilities, which can provide clear and detailed images of the object.
Illumination: Proper illumination is crucial to highlight features and contours on the part. VMMs often feature programmable LED lighting to enhance image quality.
Data Acquisition: The images captured are processed and converted into digital data. These images are then fed into the measurement software for analysis.
Software Analysis: The heart of a VMM lies in its measurement software. This software can perform a range of measurements, including distances, angles, radii, diameters, and more. It can also perform complex geometric measurements and comparisons to CAD (Computer-Aided Design) models.
Report Generation: VMM software can generate detailed measurement reports, often with visual representations, making it easy for operators and quality control personnel to understand the results.

Advantages of Video Measuring Machines

VMMs offer several key advantages that have made them an integral part of modern manufacturing and quality control:

High Accuracy: VMMs can provide measurements with exceptional precision, often in the sub-micron range. This level of accuracy is essential for industries where tight tolerances are critical.
Non-Contact Measurement: As VMMs do not physically touch the part, there is no risk of damaging delicate or sensitive components during measurement.
Speed and Efficiency: VMMs can quickly capture and analyze data, leading to faster inspection and measurement processes, which, in turn, can reduce production time and costs.
Complex Geometry Measurement: They can measure complex, 3D shapes and irregular geometries that are challenging for traditional measurement tools.
Data Storage and Traceability: VMMs often come with data storage capabilities, enabling manufacturers to maintain a record of measurements for traceability and quality control purposes.
Easy Programming and Automation: VMMs can be programmed to perform measurements automatically, and they are well-suited for high-throughput manufacturing environments.

Applications of Video Measuring Machines

Video Measuring Machines find application in various industries and fields, including:

Automotive: VMMs are used to measure engine components, precision parts, and critical components to ensure compliance with specifications.
Aerospace: In the aerospace industry, where safety is paramount, VMMs play a crucial role in measuring and verifying the precision of components used in aircraft and spacecraft.
Medical Devices: VMMs help ensure the accuracy and reliability of medical device components, including implants, prosthetics, and precision instruments.
Electronics: VMMs are used for measuring and inspecting circuit boards, connectors, and microelectronic components.
Research and Development: VMMs are employed in research and development laboratories for the precise measurement of experimental components and prototypes.
General Manufacturing: They are used in various manufacturing processes, from quality control of consumer products to ensuring precision in the production of industrial machinery.

Future Trends in Video Measuring Machines
