Temp Gage

[[Ja...]]

Hello,
My company just got our Duramax set up and online. Now the question raised is how does the machine and software know what type of material the part being measured is?

Also a side note, what is the max weight a probe tree can be on a VAST XXT probe head?

Thanks

VAST-XXT TL-3 max weight is 15 grams

You have to activate Temperature Compensation, then enter the material's coefficient of expanse (COE). This value is metric and is the amount in microns per meter per degree (C). Even when working in inches, enter the metric value.

Then, you have to be able to take an accurate measurement of the temperature of the part and enter the reading when you begin the program.

You might find more information if you search Temperature Compensation in the help section.

This link to a previous thread may help for finding the correct expansion coefficient values. I find Matweb the biggest help, a great resource site to sign up with if you're not already.

Tom, I thought the metric only input got fixed quite a while back. If not I've been entering the wrong values since.

Hi Jack,

That could be true but I just looked at the Temp Comp window on 2018. The Correction Value is always shown as "microns per meter per degree C". The coefficient value doesn't change when I change from metric to inch. So, at this point, I feel like these values are still all metric. If someone from Zeiss is reading this post, maybe they can chime in.
