The Ultimate Guide To Selecting A Good Vision Measuring System

Vision Measuring Systems

Vision measuring systems, also known as video measuring machines, are measuring instruments widely used in different industries. Many components and products in these industries have to meet a high degree of geometrical conformance and few metrology equipment can sufficiently address such rigorous demands. This is where the video measuring system comes in – it is able to inspect, measure, evaluate and/or identify objects in a fast and accurate manner.


How Are Vision Measuring Systems Different from Optical Comparators?

A vision measuring system makes use of zoom optics with better lighting and multiple sensors for a clearer resulting image. With these features, they can measure both 2D and 3D parts up to a certain precision, depending on the accuracy of the machinery. 

On the other hand, the optical comparator can only measure the 2D profile contouring of the object. 

So now you understand how a vision measuring system works. With so many companies offering a large selection of vision measuring systems, which do you choose? Below are some things to consider when selecting a good vision measuring system to meet all your metrology needs.


When Selecting a Good Vision Measuring System

1. Work with an established company with a good track record.

An established vendor, preferably with over 5 years of experience, typically manufactures their own machines or has partnerships with various distributors, giving you a wide range of products to choose from at a much lower cost. Their products offered also have significant uptime and low failure rates.

Your vendor should always be up to date with the latest functions and technological trends. As vision measuring systems make use of PC-based software, it must be regularly updated so you can get the most accurate results in an efficient manner.  

It is also wise to ask for benchmarks and sample reports so you can have a good gauge on their past track record. This is proof that they will provide reliable equipment with uncompromising quality, giving you a peace of mind that you’re in good hands.

2. Good staff training is key to getting the most out of your measurement machines.

Some vision measuring systems require trained operators to operate them. Ample support, like training and metrology seminars, should be provided by your vendor.  Some vendors even provide in-house training on the operation of the machines. Well-trained operators who understand the ins and outs of the video measuring machines can make a world of difference to your research applications, production quality, design and performance specifications.

3. Opt for a machine that meets your needs.

There are many variations of the video measuring machines, each with their own unique features to suit your needs. Some machines can be manually adjusted while others are equipped with a digital colour camera.

A few vision measuring systems also have multiple sensors like a touch probe or laser on a single machine. These multi-sensor video measuring machines are highly useful for difficult-to-reach part features. Measurement accuracy varies amongst them too.

Discuss with your vendor and opt for a machine that best suits your specific needs to maximise your budget.

4. Get a vendor that provides responsive and reliable technical support.

If your machine goes down, you need answers fast. Nothing is more frustrating than having an unresponsive vendor. Relieve yourself from this stress and work with a vendor who has fully trained service engineers that can fix and calibrate your machines quickly.
