Description / Abstract:
General
This standard covers the specification and measurement of
out-of-roundness of a surface of
revolution by the evaluation of a typical cross-sectional profile in
terms of its radial deviations
from a defined center. While this standard deals primarily with
precision spindle instruments for
out-of-roundness measurement and polar chart presentation, it is not
the intent here to exclude
other methods which will provide valid radial deviation data. This
standard does not define the
design requirements for roundness suitable for specific purposes, nor
does it specify the
manufacturing process for production of roundness.
Appendix Sections
The complexity of roundness measurements has necessitated the
publication of a series of Appendix
sections which describe other out-of-roundness indication methods,
their applications and
limitations. Other general information and specific examples of
out-of-roundness measurement may be
found in the Appendix, which the reader is urged to study. The
Appendix sections shall not be
considered a part of this standard.
