  • It’s pretty common for a CMM to be in its own climate controlled room. Parts will be placed in the room and allowed to reach reference temperature for a several hours prior to measurement.

    On production lines you usually skip the absolute measurement of a CMM and use go/no-go gauges. One should fit, one should not. They’ll be made of a material with similar thermal expansion coefficients as your parts. As long as they’ve both been sitting around for a while they’ll be at the same temp. They’ll have expanded or contracted the same amount from reference so their relationship of go/no-go will still hold true.

    The whole field of metrology is a never ending rabbit hole - really interesting the more you get into it.




  • Tangentially: Microsoft Teams and SharePoint web infuriate me daily. All the functions that should be separate programs are rolled up into one inseparable window forcing you into a single task workflow.

    Want to have two folders open at once that you can drag between? Want to copy a file to your desktop? Read a message from a colleague while looking at a planner item? Pretty much any basic task that Windows 95 can handle with ease? You’re screwed.

    These are all things that should be separate programs handled by the OS and a samba share. The MS Office ecosystem has regressed massively over just a few short years thanks to teams.
