Conclusion
Measuring workpieces and determining the correct amount of material needed
to be removed is one of the tasks performed by the machinist. The machine,

as determined and programmed by the operator. Therefore, as a machinist, it
is essential that one becomes proficient in the use and care of precision
measuring tools and gages in order to machine parts and components to the
correct degree of accuracy. Undersized or oversized work is not acceptable
in most machine shops and waste amounts to money lost. It is hoped that the
information in this lesson will enlighten you on the proper use and care of
the various measuring tools and gages.
