Configuring RevWorks for Romer Digitizers

 

Romer portable CMMs require no hardware configuration for use. When RevWorks first attempts to communicate with a Romer device, RevWorks automatically initializes the communications parameters to default values. You may need to select an alternate communications port if your Romer device uses serial communications and is not connected to the default serial communications port. You can also modify several default options to customize the behavior of your Romer device.

To Configure RevWorks for a Romer Digitizer

1. From the RevWorks toolbar, select ,
   or select Options… from the RevWorks menu.

The Options dialog appears.

2. Select the Current Devices tab.

3. From the Current Device drop-down list box, select Romer if it is not already selected.

The Options tab automatically reflects configuration options for the Romer device.

Note: If the Romer selection does not appear, RevWorks did not find a supported version of WinRDS installed on your computer or the Romer device was not selected for installation with RevWorks. This Romer-supplied software is required to communicate with the Romer device.

4. Select the Options tab.

5. In the Communications group, Select USB as the Communications Port, or
   select the serial communications port your device is connected to if it uses serial communications.

6. Select Sounds to Configure Romer Sounds.

7. Select Use As Mouse if you want to activate the ability of the Romer device to act as a mouse when not collecting point data.

8. Select Boost Thread Priority to increase the responsiveness of the Romer Device when being used as a mouse, if necessary.

9. In the Probe group, select Auto Detect to activate the automatic detection of probe definitions as you switch probe tips.

Note: Some older and customized probe tips may not support automatic detection.

10. Change the default value for the Probe Approach Tolerance if you wish to change probe motion sensitivity.

Note: The Probe Approach Tolerance must minimally be set larger than twice the inherent accuracy of the device.

11. Select Button Assignments for Remote Mouse and Data Collection Actions for each of the three available buttons.

Note: The Romer Infinite 7-axis arm has three physical buttons, but two of them (the white buttons) have the identical function and operate as button #2. If you use an external switch with three buttons, the individual button assignments apply as expected.

12. Select OK to accept the specified options.

Your Romer digitizer is now ready to start.

Probe Approach Tolerance

RevWorks tracks probe movement to assist in determining the proper offset direction for features measured with a ball probe. The sensitivity for probe movement may be adjusted by changing the probe Approach Tolerance. The probe Approach Tolerance specifies how much the probe must move before that movement registers as probe motion for the sake of determining the offset direction. The default value of 2 millimeters should be adequate for most measurements. If you are measuring features, such as a bore with a ball probe that is nearly the size of the bore, you may want to reduce the probe Approach Tolerance, if the probe cannot be moved at least the specified amount before the first point is taken. RevWorks may not be able to determine the correct offset direction unless you approach the first point of the feature by at least the distance specified by the probe Approach Tolerance. If RevWorks seems to be randomly offsetting in the wrong direction, the value for probe Approach Tolerance may be too small.

Note: RevWorks displays measurements in the same units as the currently active part or assembly document. You can enter values in any other supported unit of measure by adding the recognized abbreviation after the value you enter.
