Check.jpg MAJOR NEW FEATURE: Bend Profile Out-of-round % Measurement

Vtube-step v2.5 bendprofile scanned.png

This feature is unique to FARO systems using VTube-LASER.

VTube-LASER can now measure bend profile regions in order to calculate the out-of-round percentage in multiple slice regions of any bend.

This feature is only possible because the FARO ScanArm uses a surface scanner to collect surface points. (Other measuring methods that do not scan surface points cannot perform this kind of measurement.)

Bend Profile Measure Control

The Bend Profile measure control can be used in the middle of the Uniscan measure.

During a Uniscan tube measurement, you choose if you want to measure a bend's profile region.

To save time, VTube-LASER allows you to skip measuring the profile of non-critical bends.

About the Bend Profile "Slice" Metaphor

The metaphor "slice" is used to visualize the regions like slices of cake in the bend sections.

VTube uses these slice regions to group all surface points inside each of these regions. It then reports the one high and the one low value of the torus surface points in that slice region, and then uses those two values to calculate the out-of-round% values per slice region.

Bend Profile Out-of-round Grid

SLICE COLUMN
In the Out-of-round grid (in Inspection Results), each slice is labeled as "Bend Number - Slice Number".

ANGLE COLUMN
Then next is shown the slice region angles in degrees. The default slice region width is 10 degrees. This value is controlled in the Other tab of Measure Setup.

LOW and HIGH COLUMNS
The Low and the High values are surface point distances from the centerline arc minus the radius of the nominal OD in each slice. (Each slice can have a unique nominal OD.)

OOR COLUMN
The Oor value is the difference between the high to low. This is the technical meaning of "Out-of-round".

OOR% COLUMN
The Oor% value is calculated from the high and the low differences. (The Oor% formula does not use the nominal diameter - so you can change the nominal OD to any value with effect on the Oor%.)

Vtube-laser v2.5 bendprofile oor slice regions.png

Example High OOR% = 10.5

In the image on the right, you can see slices 5 through 10 in our mandrel bent Horn Demo tube.

Slices 7 and 8 have the greatest Out-of-round percentage at over 10.

Look closely at the center of the top of the bend, and you will see a ridge on the top of the tube is at a high point. This is where material flowed toward the top and the bottom of the bend during bending.

You may also detect the slightly reduced width from outside to the inside of the bend. All of this material flow is the reason for the OOR% at its highest in this region of the bend.

In slice 10 (OOR% of 8.4), the ridge on the top of the bend has faded, and the bend width from outside to inside is less flattened. The bend is recovering from the being out-of-round in this slice region.

VTube-LASER Demo Tube 3 OOR% = 17 to 20

This is a closeup image of the bend in demo tube 3 that the FARO account managers carry with them.

This tube was not bent with a mandrel - which allows the material in the bend region to flow more than mandrel bent tubes.

Check.jpg NEW: Bend Profile Radius Calculation

The Bend Profile measure feature also automatically calculates the centerline arc from the cloud data scanned around the bend.

Because huge amounts of data can easily be collected during Bend Profile scans with the FARO ScanArm, the calculated radius value is repeatable.

The calculated measured radii values are inserted in the measure data if VTube finds that you measured the bend profile for that bend.

This is useful especially for reverse engineering tube shapes. If you don't know the radius value in the tube shape, this feature will determine the actual average radius at the center of the bend.

Check.jpg NEW: BEFORE and AFTER TRIM Lengths Grid - Before The Actual Trim

VTube now shows the projected TRIM lengths AFTER the end deviations are removed - but BEFORE the actual trim occurs.

This allows you to know if this part will pass inspection after the excess material has been cut off.

Check.jpg NEW: Communications with AIM Wire Benders

VTube-LASER and AIM wire benders can now communicate using the Supravision Network protocol.

We added a specialized Supravision Network protocol called "AIM SVNet" just for this bender to handle the negative bend angles that arrive in Supravision data from the bender.

(Wire benders can bend in two directions - left or right. They indicate a switch in direction by making the bend angle negative or positive.)

Check.jpg IMPROVED: Best Fit - Automatic End Weight Version 2 - Tighter and Faster Alignments

We're always happy to give you a feature that does more - and does more FASTER than before. This is one of those features.

Version 2 of the Best Fit engine aligns tube shapes faster and tighter than the original. For example, a 25 second alignment is now made in 20 seconds, and a 0.013" average deviation might drop to an average of 0.009".

Version 1 was very good at tight alignments as the measured tube shape started to conform more to the master tube shape. However, version 2 creates a tighter fit faster - and handles shapes that are further from the master shape much better than version 1.

The alignments shown on the right are the results of the two different kinds of alignments now available in version 2.5. We used the same master/measured data. When qualifications are on the edge of the tolerance, then the new version 2 of Best Fit has a better chance of qualifying a tube.


Note: We understand that some customers are very careful when approving new part alignment algorithms - so we were careful to leave the original version Best Fit option in the VTube Inspection Results menu to give you time to learn to trust and use Best Fit version 2.

Check.jpg IMPROVED: The MEASUREMENT COMPLETE Window is Redesigned for Simplicity

The Measurement Complete window is the window that displays when you finish measurements. It has been redesigned to make it even easier to use.

We've removed all the extra alignment buttons and now there is only one. There is a new dropdown box that allows you to chose the alignment - and make it the instant default in the current project. (This means that all other interface objects in other windows that show these settings change instantly when you change the alignment type here.)

Here's another enhancement: We caught a user accidentally pressing "Do Nothing and Close" after a measure. This basically deletes the current measure. So now VTube will always ask for confirmation before accepting that as your choice.

Check.jpg FIX: Floating Point Numbers with Commas

Previous versions of VTube had difficulty handling number systems that uses commas as a decimal symbol.

For example, Inspection Grids would not display colored cells like they should.

This has been fixed.

Check.jpg NEW: Project File Save Notification Proves the Project Was Saved

Vtube v2.5 savedfilewindow alone.png

Previous versions of VTube were quiet when you saved a project file. That made some of our customers understandably nervous.

So now VTube always shows a quick notification at the top of the screen when you save a project file.

The window displays for a few seconds then disappears automatically. But you can even keep working when this window is open because you can click on other parts of VTube even while this notification is on the screen.

Check.jpg NEW: HOT Keys Control-L (Load) and Control-S (Save) for VTube Project Files

These new hotkeys are a simple thing- but they'll make your life much easier if you're a hotkey user.

Try it. Press CTRL-L to load a project file, then CTRL-S to quickly save it again. It's about as easy as it gets.

(The new project save notification window described above will display every time you press CTRL-S.)

Check.jpg NEW: CALCULATE TUBE ELONGATION PERCENTAGE FEATURE

Now VTube-LASER can calculate Tube Elongation Percentage by subtracting the current CUT LENGTH from the MEASURED LENGTH - then calculate the percentage by comparing that change to the total ARC LENGTHS in the measured tube.

The formula used is (Measured Length - Cut Length) / (Arc Length Sum for Whole Tube) X 100

Check.jpg ENHANCEMENT and FIX: The PROBE RADIUS COMPENSATION Feature

If you measure the ends of tubes with the ball probe, and the probe radius compensation directions at either end are ever different, then this update is critical for you.

CHANGED CAPTIONS IN SETUP
The captions in these boxes used to read "Offset End A" and "Offset End B". This was too vague, so we changed the English to "Probe Radius Compensation - End A" or "...End B".

IMPORTANT FIX FOR TACTILE END MEASURES
Also, we discovered and fixed a bug where VTube always used the probe compensation setting End A for End B too.

This would have created an incorrect compensation direction if the settings for either end were different.

For example: They would be different if you were tactile measuring the end wall of the tube on End A, then tactile measured where a flange meets the tube diameter on End B (on the tube side of the flange).

Check.jpg FIX: Transfluid XYZ Output (BKT File) Repairs

This feature allows you to output new XYZ data to the bender from inside VTube-STEP (which is part of VTube-LASER).

The output engine for Transfluid XYZ data was updated and repaired from errors we found that would stop the export.

Also, the linear units are now converted to whatever the current linear unit is in the VTube user interface. This was added because the internal Transfluid data can be either inches or millimeters.

Check.jpg NEW: Tangent Point Reports

VTube can now output Tangent Point reports.

Tangent points are the point locations where the straights meet the bends on the tube centerlines.

Check.jpg NEW: Huntington Ingalls Data Import

VTube can now import Huntington Ingalls data for shipbuilding applications.

Check.jpg OTHER CHANGES

  • When decreasing the point count in VTube-LASER without clearing the project, the reports would continue to show the previous expanded point count for the Tangent Points and Midpoints list. This has been fixed.

  • The Overbend Calculator incorrectly swapped the Proportional and Fixed values in the springback formula for the springback grid inside the calculator. This has been fixed.

  • The Springback compensation, when enabled, was not calculated correctly in outgoing Supravision files. This has been fixed.

  • The End B Length Adjustment feature would not draw the tube diameter correctly when set to more than or less than 0. This has been fixed.

  • The default straight tolerance value is now used to automatically fill in tolerance fields in the grids with tolerances. (Previous versions would always use 0.039" or 1 mm for the tolerances in inspection grids.)
