#### Vision: Gear Measurement Setup

Measure Gear dialog box – Vision

You can use the Measure Gear dialog box as follows by selecting the appropriate check box(es):

Generate: When you select this check box, PC-DMIS will generate your part program, but will not measure unless the Measure check box is marked.

Measure: When you select this check box, PC-DMIS Gear will generate and execute the part program to measure the gear. Otherwise, the part program will be created, but not executed.

Evaluate: When you select this check box, PC-DMIS Gear will automatically evaluate the gear and create a report as soon as the measurement is completed. Otherwise, you will need to open the Evaluate Gear dialog box to evaluate the gear.

Part Program Area

The Create a new part program and Open an existing part program options allow you specify whether PC-DMIS Gear should create a new PC-DMIS program to measure the gear or if it should use an existing PC-DMIS part program. Specify the name of part program by typing the path and name for part program or clicking the browse button to select the part program file. The path to this probe file will appear in the Part program name box.

Alignment Area

Align File: This box lets you determine the alignment file to be recalled and used in the gear measurement program. By default, PC-DMIS Gear automatically selects the alignment you performed using the Align Gear icon. Use the Browse button to select the alignment file (file with an .aln filename extension). For more information on alignment files, see the topics on saving and recalling alignment files in the main PC-DMIS documentation.

Probe Area

Probe File: The path in this box defines what probe file you want to use for the gear’s measurement. Click the Browse button to navigate to and select the probe file to use for the gear’s measurement.

Edge Settings Area

Density Level: This list lets you define the density type when detecting the edge of a feature. It has three options:

Low: Returns a minimal number of points (one point for every 10 pixels). Use this density type if your feature form doesn’t change much in this area, or isn’t a critical area of your part.

Normal: Returns the default number of points (one point for every 4 pixels) for that feature type.

High: Returns the maximum number of points (one point per pixel). Use this density type if your feature form changes drastically in this area or is considered a critical area of your part.

Outlier Filter: This check box determines whether or not outlier filtering is required for this target.

Std. Dev.: This box defines the standard deviation of a point. This is the distance a point needs to be away from the other points to make it considered to be an outlier.

Color Settings Area

Hit Target Color: This list allows you to select the color used for most of the overlaid graphics and text on the Live View tab. This affects probe hits, targets, gages, as well as textual information for FOV coordinates, magnification, and focus. The default color is red.

Nominal Color: This list allows you to select the color used for the nominal line in the targets on the Live View tab.

Magnification Area

Opt. Magnification: This determines the optical magnification percentage to use when measuring.

Illumination Area

This area controls the illumination used for the different styles of lamps. Each lamp has its own check box, slider, and Intensity box. The check boxes switch that specific lamp on or off during measurement, the slider bar and the corresponding box determines the intensity of that lamp. The available lamps are:.

Top Light: This lamp is an on-axis lamp that is directed through the optical path. It can provide better edge and feature visibility on some parts than other light sources that illuminate from above because the light source isn't as diffused. Since it shines parallel to the optics, it's also easier to see into holes.

Bottom Light: This lamp that shines from under the stage. It creates a silhouette of the part to be viewed.

Ring Light: This is a multi-bulb lamp that illuminates from above. This lamp is normally composed of an array of LED lights arranged in concentric rings or circles.

The following buttons are available in this dialog box:

| To start the gear measurement and vision machine movement, click this button. PC-DMIS Gear will generate the measurement program if the Generate check box is selected, measure/execute the program if the Measure check box is selected, and Evaluate the gear if the Evaluate check box is selected.

A message will appear and ask if you are ready to start measurement. To run the gear measurement program, click Yes. To cancel the measurement, click No.

Once the measurement process starts, PC-DMIS Gear will open the Execute dialog box. Follow the instructions in the Execute dialog box to proceed. For more information, see "The Execute Dialog Box".

| This button applies any changes you have made and leaves the dialog box open.
| This button cancels your changes and closes the dialog box.
