Introduction
Video Measuring Systems (VMS) use cameras and intelligent software to measure parts accurately. Whether in manufacturing, medical device making, or aerospace, VMS can help you get precise measurements quickly and automatically. No more fiddling with calipers or guesswork—just clear, reliable results.
Here’s a walk-through of VMS, how they work, the different types, and how they’re changing industries.
What are Video Measurement Systems?
Video measurement systems (VMS) are precisely as they sound. They’re cutting-edge tools that harness the power of video technology for accurate measurements. A VMS uses powerful cameras and special software to analyze an object’s size, shape, or position.
Instead of using calipers, the system captures an image or video of an object and digitally analyzes it for precise measurements. Thanks to this tool, you can now measure even hard-to-measure objects like tiny machine parts. It’s like taking a picture of the object and then using it to figure out how big or well-made it is.
Types of Video Measuring Systems
Video Measuring Systems also have various types. Each one offers specific capacities for different applications.
1. Standalone Video Measuring Machines
“Standalone” refers to the ability of these machines to operate without a separate computer. To measure an object, you simply place it on the machine’s platform and let its camera shoot images. Such a machine is a common manufacturing and quality control centerpiece to verify a part’s dimensions.
2. Integrated Video Measuring Systems
In contrast to Standalone VMMs, this one integrates one or two external equipment. It’s common to have an integrated video measuring system with a CNC and a coordinated measuring machine (CMM).
3. Portable Video Measuring Devices
VMS aren’t always bulky, as seen in most of their applications. They can also be compact and handheld, like a Portable Video Measuring Device. This mobile device allows its users to measure objects on the go, making field inspection much less challenging.
4. Multi-Sensor Video Measuring Systems
This device packs the prowess of an optical camera and the unmatched accuracy of lasers and touch probes. The optical camera is responsible for visual measurement, the laser for depth, and the probes for precise contact measurement.
5. CNC Automation Systems
These systems are key to unlocking automated video measurements. The CNC automatically moves the object following a three-axis path, making consistent and repeatable measurements possible without manual intervention. You’ll often find these systems working in high-precision, high-volume manufacturing.
6. Manual Systems
Manual systems are the old-school method, in which you measure by hand. You adjust the equipment and measure parts with tools like calipers or manual video machines. It’s slower but still useful for custom jobs or small batches.
Key Components of Video Measuring Machines
Here are the components that build up a video measuring machine as a dynamic system.
High-Resolution Cameras
The centerpiece in VMMs is high-definition cameras that capture clear and precise photos for visual measurement. Think of these as the “eyes” of the machine. They take really clear, detailed pictures of the part you’re measuring. The sharper the camera, the more accurate the measurements will be.
Precision Optics and Lenses
High-quality lenses and optical systems boost the cameras’ precision and resolution. Just like a good pair of glasses helps you see clearly, precision optics ensure the camera captures every little detail of the part without distortion.
Measuring Stages
This is where the part sits during measurement. It’s like a platform that can move the part around in different directions (up, down, side to side) so the camera can take measurements from all angles.
Lighting Systems
Lighting is key for clear pictures! The machine uses special lights to ensure that the part is well-lit and that shadows don’t hide any details. Good lighting helps the camera see everything clearly, which leads to accurate measurements.
Image Analysis Software
After the camera takes the pictures, this software processes them. It looks at the images, identifies edges and shapes, and then calculates your exact measurements. This software automates much of the work, making the process faster and more accurate.
Control Systems
These are the buttons or screens you use to control the machine. With these controls, you can move the part, adjust the settings, and start the measurement process. It’s like the “remote” for the whole system.
Calibration Systems
Calibration ensures the machine is working correctly. Over time, parts can wear out or shift slightly, so the machine checks itself to make sure it’s still giving accurate readings. It’s like tuning up your car to keep it running smoothly.
Core Functions of Video Measuring Machines
Precision Measurement Capabilities
The VMM’s main job is to measure parts with extreme accuracy. It can measure tiny details—down to micrometers—without needing to touch the part, which means it’s perfect for delicate or complex shapes. Whether you’re measuring the width of a small hole or the length of a part, it gives you precise measurements every time.
Advanced Imaging Capabilities
The VMM uses high-definition cameras to take detailed images of your parts. These cameras capture everything clearly, even small features that might be hard to see with the naked eye. This lets you get a really good look at the part and ensures you can measure even the tiniest details.
Geometric Analysis
Once the images are captured, the VMM analyzes the part’s shape and geometry. It calculates angles, curves, and distances between features for precise measurements. The system automatically checks if parts meet shape requirements, like circular holes or 90-degree corners.
Tolerance Verification
Tolerance is the amount of variation that is acceptable in the part’s measurements. The VMM can compare your part’s measurements to the design specifications and check if they fall within the allowed limits. If the part is out of tolerance, the machine will alert you, making it easier to catch errors early and ensure quality.
Automation Controls
Many VMMs have automation, so you can set them up to take measurements independently. You don’t have to adjust anything manually—the machine will move the part, adjust the camera, and check different points automatically. This saves time and keeps everything consistent, making it perfect for high-volume work.
The Role of Video Measuring in Different Industries
Here are the various industries where and how video measuring is being employed.
1. Manufacturing industry
In manufacturing, VMMs are a game-changer for quality control. They ensure parts are made to the correct size and shape, reducing mistakes and speeding up the process. Since they can work automatically, they help check many parts quickly and consistently, which is perfect for busy production lines.
2. Medical device manufacturing
It’s important to get the measurements right when making medical devices like implants or surgical tools. VMMs help ensure these parts are the right size and shape, which is crucial for safety. They also make the process more efficient and accurate, setting aside human errors.
3. Aerospace industry
VMMs measure parts for airplanes and spacecraft in aerospace, where safety is everything. These machines check that every part meets strict performance and safety standards. VMMs ensure every little detail is perfect before a part is used in something as critical as an airplane.
4. Automotive industry
In the automotive industry, VMMs measure all kinds of car parts, from engines to interior components. They help ensure everything fits together perfectly and meets safety standards. Whether checking for tiny defects or ensuring parts are the right size, VMMs help keep the production line running smoothly.
5. Electronics and semiconductor industry
In electronics, parts like microchips and circuit boards are tiny and must be measured precisely. VMMs check if tiny details like solder joints (the connections between wires) are correct. It’s like making sure the pieces of a tiny, delicate puzzle are in the right spots so the whole thing works properly.
