Appendix A Profile measurement
Magnifying the display of form error whiskers
During the fit operation, points acquired that do not fall precisely on the
nominal profile generate form errors. When tolerances are specified, the
errors are divided into two groups, those that pass (Passed) and those that fail
(Failed) tolerance criteria.
The passed and failed errors can be displayed
as whiskers that extend orthogonally from the
nominal surface. The length of each whisker
is proportional to its magnitude of error.
Typically, the magnitude of most form errors
is so small in proportion to the part displayed
that without magnification they would not be
visible. The Error Mag menu item provides
fixed, automatic and user-definable levels of
magnification for displaying error whiskers.
Error magnification levels are also available in the profile toolbar.
NOTE
The Show/Passed or Show/Failed menu item must be checked or toolbar
icon must be clicked for whiskers to be displayed.
Fixed magnification
Click the Error Mag menu item, then
click the desired level of magnification,
or click the desired level icon in the
toolbar.
Automatic magnification
Click the Error Mag menu item, then
click AX for automatic adjustment of
magnification, or click the AX icon in
the toolbar.
When automatic magnification is se-
lected, the system optimizes the dis-
play of error whiskers based on the
maximum form error value.
