HxGN Live Hong Kong 2015 - Power of large data for 3D metrology and process c...Tal Vagman
Hexagon Manufacturing Intelligence and other Hexagon group divisions address big data challenges as companies accumulate larger and larger data sets. Investment in technology and Enterprise scale software systems aims to provide better management, interoperability, and analytics.
This way critical insights enabled by Big Data would indeed significantly improve operational performance.
In the Automated Solutions group whose production integrated metrology systems are operating on a 24/7 basis, innovations are continuously being developed in this domain. On the one hand sensors are enhanced to acquire even more data faster than before and on the other hand to compress Big Data, reduce its complexity and make it more accessible to a larger audience of technicians, engineers and managers.

We are learning from our End user and OEM customers that demand for higher accuracy and precision is growing.
As well as increased efficiency and monitoring
Traditional laser calibration has been the “go-to” method for high accuracy error measurement and compensation
But we are learning that more and more, compensation alone is not enough.
We are finding that our OEM customers more and more want to understand the contributing factors to their machine tool errors at the verification stage
They want accurate and comprehensive information and they want it quickly.
This allows them to continually improve the performance and quality of their machines
To do this we need to start thinking about the 6 degrees of freedom …and not just linear
To give an example of how seeing all 6 dofs allows us better pattern recognition and identification of root cause.
Here we see the linear error …quite large
And then we can quickly spot that pitch and vertical straightness have a similar shape
Our rule of thumb is “angles cause translations” so we can know that pitch is causing the linear error…and it is also affecting the vertical straightness
That’s the obvious stuff
But roll is a little sneakier….
Lets say our “point of interest” is offset by about 65mm in Z
We can now see the difference between where we measured previously and what the result is at our POI
We are now sure that there is a roll issue and that it is causing straightness to be much worse at our POI
We would not have seen this if we weren’t conscious of roll
We usually expect rails to be straight and parallel
But this is actually quite difficult to do in order to eliminate roll
This is because roll is present whenever there is a difference between the two rails
And it is almost impossible to make both rails perfectly parallel
Here we start to see what is really going on.
If we look at roll also at the same time, we can see that we have the same general shape as the Horizontal straightness.
Identifying where the peaks are is another way of spotting correlations
Here is the Horizontal
And here is the horizontal and Roll
We can see from the ‘peak’ that the roll is DRIVING the straightness
Roll shows us that this is actually a rotational or rolling motion
This is the REAL problem and fixing roll requires a different approach
Finally, if you are unsure if what you’re seeing is roll or straightness, a way to check, is to measure straightness at different heights to see if Roll is the real issue.
This is because roll makes straightness worse with height….we call this offset errors
Lets say our “point of interest” is offset by about 65mm in Z
We can now see the difference between where we measured previously and what the result is at our POI
We are now sure that there is a roll issue and that it is causing straightness to be much worse at our POI
