  • Cylinders keep tipping over!

    OK, so here's the skinny on my cylinder issue.

    I am checking several Cylinders (shaft holes, and pockets) using auto features. Of the four that I am checking, two of them keep lying down.

    It looks like my vectors are getting screwed up some how. Any suggestions?

    See the attached image for clarification. In the photo I am only showing the pocket that is having problems, I also have a shaft hole experiencing the same problems.

    BTW, I hate Saturdays at work!

    Generally:

    Cylinders measure best with:

    Use three rows instead of two will probably do it.

    Measure the furthest extent of the cylinders, as close to the end as is practical.

    It also helps if you don't use four points per row.

      Why is it that the simple solutions always evade me?

      Thanks a lot! You made my Saturday a little bit better. If you can get me a case of Coronas it'd be a perfect day!

        Try Polar Instead Of Rect, Three Rows Instead Of Two, Are You In A Quiet Environment, Are Your Measured Dia. Sizes Correct, Or Close?

          Ha...just had a run along the same lines. Instead of four pts in two rows, I bumped it to five and all was well. Of course with 30+ holes it was an annoyance....
