Features
Features consist of data points obtained by probing the geometry of the part.
For example, several points probed along the perimeter of a circle generate a
graphic and numeric representation of the measured circle geometry. In this
guide, a measured geometry is referred to as a feature. Features are displayed
graphically or numerically on the QC200. There are several types of features and
each has different distinguishing information. For example, a circle has a center
and a radius, a point has a location, and an angle has degrees.
Features list
Each feature is added to the features list when it is measured. The features list is
simply a listing of all features measured in a given session. It is displayed on the
left-hand side of the LCD screen and is visible in DRO and measuring modes.
Features are identified by number and an icon indicating its type (i.e. circle, line,
etc.). Up to 200 features can be added to the features list. Use the up and down
arrow keys to scroll through the list. Highlight the desired feature to recall, print,
or send the feature data to a computer. Select features from the features list to
construct new features. Users can also delete individual features or the entire list.
In general, the user should delete old features, datums, and skews from the
features before each new inspection.
Probing Features
There are two probing methods used to collect data points for the QC200:
crosshairs and optical edge detection. To collect points using crosshairs, align the
crosshairs over the desired point and press the enter key. Optical edge detection
takes points at light-to-dark (or dark-to-light) transitions. When an edge is
crossed the QC200 beeps. Press the enter key to accept the point. Systems
equipped with auto-edge detection enter points automatically when an edge is
detected.
