Tesa 300 questions

[kbotta]

A few questions:
1. Is there a trick to doing the manual alignments? Can't seem to get it to work like normal CMM. Keeps asking me to pick something out in space...??

2. Does Pcdmis lock up on you a lot using tesa 300? V4.2 ....

3. Can you somehow marry the "cad screen" and the "live screen" so I can see my features that have been measured on the live portion of the software???

Locked up, and I lost everything...(I know save3, save often--> Not my 1st carnival...:) )

1 are you using manual hit targets or automatic hit targets? In either case you should be able to manually position the targets over the feature.

2 dont know as I run a mycrona

3If you want to see both screens at once look at the magnification tab in your probe toolbox while viewing your graphic display. That will give you both views.

I have it in manual mode when selecting my manual alignment features. The plane points seem to work fine.
The line pts and the circle are screwed though.
How is it that I should be able to position the target over the feature? My target is moved WAY off. Can I click and drag the target over my feature??
Thanks!

Could you post code? Maybe a screen cap as well?

[kbotta]

Here's what happened. I got it to work. I had to origin 1st, than rotate, than level in order to get the manual alignmetn to work. Completely backwards from the normal CMM. But - it works.

I'm glad you got it resolved. Welcome to the joy that is PCDMIS vision. Watch out for anything requiring top lighting. It requires much tweeking to the hit targets, illumination and a lesser degree focus. Even then top lit features have given me sketchy results. Hopefully, V4.3 will resolve these issues.

V4.3 has some improvements to Matching Edge algorithm (the best algorithm to use with top lit parts), particularly for multiple field of view circular features.

[kbotta]

is 4.3 available yet?

[slesholdofthreep]

Kbotta,

Officially no. But you might check out ftp://ftp.wilcoxassoc.com/Vision/. Proceed at your own risk

[slesholdofthreep]

I just checked out ftp://ftp.wilcoxassoc.com/Vision/TESA/ and there is no V4.3 link. I guess this will take further investigation.

You might try seducing Ironman. . . :rolleyes:

I'm not sure what gives with this thing, but it deleted the recall porition of a bunch of my alignments. Won't read a fresh dcc alignment to "find the part" before it does measurments....GGGRRRRRRRRR!!!!!!!!!!

[kbotta]

Update,
I believe I have the alignment deal licked. It still doesn't like small arcs and radius's - location seems to move.
I'm still having problems with the laser and -z- axis. I would love to be able to use iterative alignments, but without the laser acting properly (like actually picking up the surface) I cannot use the 3 points to "level"...

The laser on the VISIO300 is not a measurement sensor, it is a positional laser pointer, so will never do measurements. You would need to use the video auto focus to measure the Z (vision surface point features). As a rule of thumb, set the measuring time In seconds) to be double the distance (in mm).

[kbotta]

what is the positional laser for? Does it help in detecting a edge? There for what?

[nkayWAI]

It's primary purpose is positioning. As it's in line with the optics, if you are struggling to position the camera on a feature (when programming or manually aligning), you can switch the laser on (the Laser toggle button in the bottom right of the probe toolbox). You can then see the laser spot on the part, and move the stage so the spot is over the feature to be measured.

It's secondary purpose is that it can help auto focus on parts/materials where you are failing to illuminate properly with just the lamps. There is an option in the focus parameters (Laser On/Off) - which if on will switch the laser on during the video focus operation. It is still doing a video focus, not a laser focus. Having the laser can sometimes help to illumination surface texture, which will help the focus algorithm - which is looking for image sharpness.

Vision systems with TTL or WLS lasers (Optiv, Mycrona, VISIO500) will use Laser Surface Point features to make the laser do the actual measurement.

Thank you for the clarification!!!
