### Editing Measurement Parameters

This topic discusses the various Measurement Parameters that are used to measure your gear.

Select the Measure | Measure menu option or the Measure toolbar icon to open the Measurement Parameters dialog box with the Topograph and Pitch/Runout options selected.

Probe Area

- Probe File: Browse to or type the path and name of the probe file.

- Calibrate: Clicking this button will launch PC-DMIS and allow you calibrate your probe. See "Calibrate Probes".

- Use multiple tips: Select this option when using multiple tip angles to measure the gear, instead of single angle. For example, when you select Use multiple tips, and set "A" Angle to 90, SBG will find all of A90BXX angles to measure the gear.

- "A" Angle: Provides the "A" angle that will be used to determine the tips angles that will be used to measure your gear.

- Analog Probe: Select this option if you will be using an Analog Probe.

- Mode: Select either Touch Trigger or Analog Scan to determine how measurement will be taken. The Analog Scan option is only available when the Analog Probe option is selected.

- Scan Speed: Provides the speed at which Analog Scans will be performed.

Alignment Area

- Align File: Browse to or type the path and name of the alignment file.

- Build: Click this button to open the Create Alignment dialog box. See the "Creating a Gear Alignment" topic for information on building your alignment.

CMM Options Area

- Prehit Distance: Provides the distance away from the surface where PC-DMIS starts searching for the part.

- Retract Distance: Provides the distance the probe retracts from the surface after taking a hit.

- Touch Speed: Provides the speed at which the CMM takes hits. The value that is entered is a percentage of the maximum machine speed, and cannot exceed twenty percent.

- Move Speed: Provides the point to point positioning speed of the CMM. The value that is entered is a percentage of the maximum machine speed. It can be set to any value between 1 and 100% of full machine speed.

- Fly Mode: If you select this option the CMM will move the probe around the part in a smooth and round motion. This option depends on the capability of your controller being able to execute circular moves.

Measure Items Area

- Topograph: Select this option and click Define to edit the Topograph parameters. See "Defining Topography Data".

- Pitch/Runout: Select this option and click Define to edit the Pitch/Runout parameters. See "Defining Pitch/Runout Data".

- Master Flank: This option is available when you have selected the Measure | Master Flank menu option have been selected. See "Defining Master Flank Data"

- Use existing programs: Select this option if you plan to use existing Alignment, Topography, and Pitch files.

- Recreate alignment: When this option is selected, the alignment process will be executed again to recreate the gear alignment. See "Creating a Gear Alignment".

- Program Files: Browse to or type the path and name of the Alignment, Topography, and Pitch part program files. Using an existing SBG program allows you to measure the gear without needing to take time to generate programs again.

- Clearance distance: Specifies the distance the probe will retract after measuring each flank.

- Clearance height(Z coordinate): This determines the location above the gear that is considered safe for the probe to change angles.

- Move out after each row of points measured: This causes the probe to move out to the specified Clearance distance from the gear after each row has been measured.

- Apply: Click this button to save your changes to the gear file.

- Close: Click this button to close the Measurement Properties dialog box without saving changes.

- Measure: Click Measure to begin the gear measurement process. All probing points and the machine movement is generated by PC-DMIS Bevel Gear. You will be prompted to start measurement.

Click Yes to start and No to Cancel. PC-DMIS will run your part program automatically.
