#### Defining Scan Settings

Scan Setting dialog box

The Scan Setting dialog box appears when you click the Scan Setting... button from the Gear Measurement Setup dialog box.

Profile Area

Point Density: Determines the amount of allowable hits per mm that will be created during a Profile scan.

Scan Speed: Allows you change the speed at which the CMM will scan the profile. The value that is entered is a percentage of the maximum machine speed. This is only used for an Analog Scan type.

Helix/Lead Area

Point Density: Determines the amount of allowable hits per mm that will be created during a Helix/Lead scan.

Scan Speed: Allows you change the speed at which the CMM will scan the helix/lead. The value that is entered is a percentage of the maximum machine speed. This is only used for an Analog Scan type.

Boundary Area

Boundary Type: Boundary types are described in the "Boundary Type area" topic of the Core PC-DMIS help file. Select the needed boundary type from the drop-down list:

- Plane

- Sphere

- Cylinder

- Cone

- OldStyle

Crossing Number: Determines how many times a scan crosses the selected boundary type before stopping the scan. See the "Boundary Type area" topic of the Core PC-DMIS help file for more information.

RADIUS or ANGLE: This value determines the radius for Sphere or Cylinder Boundary Type and the cone apex angle for a Cone Boundary Type.

Execution Mode: In DEFINED mode Gear will calculate all nominal scan points according to the gear parameters and insert them into the scan command. When executing the scan, PC-DMIS will pass through every point. In RELEARN mode, Gear will also calculate the nominal scan points, but when executing the scan, PC-DMIS will recalculate all scan points according to the start point, the end point and the scan direction. All learned measured data will replace the existing measured data. The Execution Mode options are only available for an Analog Scan mode.
