4 Uses Of A CMM Machine In Your Business

Coordinate Measurement Machine

It’s of extreme importance that the object’s geometric characteristics and physical dimensions match that of the 3D model in manufacturing functional prototypes and end-use parts. The entire production process can get jeopardized by even the slightest measurement errors. 

As a result, manufacturers have to go back to the first step. Of course, that’s something that businesses wouldn’t want to experience regardless if they’re doing high or low volume manufacturing.

Optical comparator and hand tools were the conventional methods for visually taking measurements. The problem with these tools, though, is that they have limited accuracy. They also require significant time to work.

There was a need for a more accurate and faster method. Thankfully, coordinate measuring machines (CMMs) came. Using coordinate processing technology, a CMM measures a part’s height, width, and depth. Coordinate measuring machines can also measure the target object, record the measurement data, and get geometric dimensioning and tolerancing measurements automatically.

What Is A Coordinate Measurement Machine And How Does It Work?

There are plenty of resources online to help you find out more information about CMM machines, including their various types. However, there are some pieces of information in this article that can help. 

Coordinate measuring machines or CMMs are devices that measure an object’s physical and geometrical characteristics. They may be computer-controlled or controlled by a human operator manually. The CMMs can also be used for testing an assembly or part against the design intent in the manufacturing and assembly procedures. A probe that’s usually located in the device’s third moving axis helps define the measurements.

A coordinate measurement machine generates points, which companies can analyze using regression algorithms. The CMM does that by precisely recording the object’s coordinates. The analyzed points can then be used for feature construction. As already mentioned, a probe helps collect these points. It can be positioned via Direct Computer Control or manually by a human operator.

The CMMs that use DCC or Direct Computer Control is like a specialized industrial robot form because they can measure the same parts repeatedly if programmed that way. 

What Are The Uses Of CMMs In A Business?

There’s a whole range of uses for a coordinate measurement machine in a business. Here are the primary ones:

Measuring Complex Surfaces

The measurement of complex surfaces is CMM’s primary purpose. The device works to its full potential when used for parts or components with atypical finishes such as pump impellers, airplane wings, and turbine blades. If you’re making the same parts in large batches, automating them is possible even if they’re so precise and have to be checked one by one. However, a machinist manually measures such parts in the majority of cases.

Checking Of Form Deviations And Relationship Of Parts

Dimension errors aren’t the only things that characterize most of the high-quality parts in the manufacturing industry. These components are also about their position or relationship to one another and their surface forms’ precision. Ensuring the smoothness of movement and decreasing vibration in revolving parts require the checking of those deviations. The good news is that manufacturing businesses can do it fast and accurately with coordinate measurement machines’ help.

Quality Assurance

The success of the outcome of the production of a functional part or prototype entirely depends on the component’s accuracy and precision. That’s why measurement technologies like a coordinate measurement machine are essential now that rapid manufacturing techniques can produce more complex objects.

The best thing about CMMs is that they offer manufacturing businesses a more reliable and quicker path to measuring parts. They don’t require components to be removed from the production floor or taken to a laboratory, unlike other measuring methods.

It’s no wonder why many companies are also utilizing coordinate measurement machines as a cheaper yet more effective form of quality control. Yes, you heard it right. That’s because although various tools that can digitally perform measurement and analysis of parts exist, few are as reliable as CMMs. You can confidently verify your design’s every aspect through CMM services like reverse engineering, tool certifications, CAD comparison, and dimensional analysis. 

Ultimately, coordinated measurement machines reduce production costs and time.

Sending Out Warning Signals

Thermal drift, tool wear, and other errors or defects can be indicated by the measurement of machine parts. There’s a need for businesses to remind their relevant personnel to take timely remedies or measures if oscillations, increased friction, and dull knives are found by measuring the form error’s geometrical parameters. The CMMs can help catch these inaccuracies.

Final Thoughts

The aims your business wants to achieve should tell you how to use a coordinate measurement machine. The device gives manufacturers like you many opportunities because of its precision and versatility. Businesses can utilize CMMs as part of their automated manufacturing machine. The device can also be used after machining or when measuring existing components set to be redesigned. Indeed, coordinate measurement machines are a revolutionary technology that will benefit anyone in the manufacturing industry.
