### Gear Measurement Setup

Measure Gear dialog box

Generate: If you select this check box, PC-DMIS Gear will generate a new part program to measure the topography and pitch of the gear according to the parameters specified in the Define Gear dialog box.

Measure: If you select this check box, PC-DMIS Gear will execute the part program specified for the Topo. File and Pitch File options in the Program Files area.

Evaluate: If you select this check box, PC-DMIS will automatically evaluate the gear and create a report as soon as the measurement is complete. Evaluation can be selected only if the Measure check box is selected.

Program Files Area

Topo. File: Type the name of the PC-DMIS program file, along with its full path, to measure the topography. You can click the browse button and select the part program file. The name of the PC-DMIS program file will appear in the box.

Pitch File: Type the name of the PC-DMIS program file, along with its full path, to measure the pitch. You can click the browse button and select the part program file. The name of the PC-DMIS program file will appear in the box.

Alignment Area

Align File: Type the path and filename of 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 icon.

You can click the browse button and select the alignment file. The name of the file will appear in the box. For more information on alignment files, see the documentation on saving and recalling external alignments in the main PC-DMIS documentation.

Probe Area

Probe File: Type the name of the probe file, along with its full path, that you want to use for measuring the gear. You may click the browse button and select the probe file name. The probe file name will appear in the box.

Use Alternate Probe File For Topography: Check this box to specify the use of a different probe configuration for measuring the topography than the probe configuration used for measuring the pitch. When this is checked, the Probe File is enabled.

Probe File: The path and name in this box specify the location of the alternate probe file for measuring the topography.

Use Multiple Tips: To specify that PC-DMIS Gear should use multiple tips to measure your gear, select this check box. If you have an indexing probe and want to use more than one probe tip, you should select this option.

"A" Angle: This option becomes available when you select the Use Multiple Tips check box. Type the “A” angle that will be used for the measurements. The “A” angle of the probe remains constant. If you use a star probe and you do not want any probe head rotation, type zero in this box.

Use analog probe: Select this check box if you are using an analog/scanning probe to measure the gear.

Probe has wrist: Select this check box if your probe configuration is using a wrist. In PC-DMIS, a probe configuration with a wrist uses the tip naming format “T1AXBY”, where X and Y are the angles of the wrist (for example: T1A90B180). For a fixed head probe configuration, PC-DMIS uses tip naming format “TIPX”, where X is the TIP #.

CMM Options Area

In this area, specify the parameters that control the motion of the machine while executing the gear measurement program.

Prehit distance: Type the distance from the theoretical point at which the motion speed changes from Move Speed to the slower Touch Speed. The distance is specified in current part units (inches or millimeters).

Retract distance: Type the distance the probe retracts from the surface after taking a hit. The distance is specified in current part units (inches or millimeters).

Check distance: Type the distance past the theoretical hit location that the machine will continue to search for the surface of the part until it determines that the surface is not there.

Clearance distance: Type the distance the probe will retract in the XY direction. The distance is given in current part units (inches or millimeters).

Clearance height: Type the distance the probe will retract in the Z direction. The distance is given in current part units (inches or millimeters).

Touch speed: Type the speed at which the CMM takes hits. The value entered is the percentage of the machine’s defined top speed.

Move speed: Type the point-to-point positioning speed of the CMM. The value entered is the percentage of the machine’s defined top speed.

Fly On: The Fly mode provides a way to move the probe around the part in a smooth, non-stopping motion. Check this box to select the fly. This option depends on the capability of the controller to execute circular moves.

Fly Radius: Type the radial distance of the arc path along which the probe will travel between move points.

Scan mode: This option is used for analog probes (such as an LSPX1S probe). For an analog probe, you can scan the profile and helix/lead in either Touch Trigger mode or Analog Scan mode. Select the appropriate type in the Analog Scan list.

Click this button to define the scan settings used in the Scan Setting dialog box. For more information, see "Defining Scan Settings".

Move out after each row of points measured: Select this check box to move the probe to the specified clearance distance from the gear after measuring each row.

| This button starts the gear measurement. 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.
