Base alignment match help

[[AG...]]

I have not used Base Alignment Match before. I have a part that is 120" and my table is 60". I have looked up how to use it and i found a programmer that explained how. So i went in and set up my initial Base Alignment for the first part. I then went and ran the alignment. I picked up all my features as it said to do, i projected points on the features that i was going to use for the Base Alignment Match. I then made all my Characteristics like it instructed me to do. Then i went and selected Base Alignment Match placing it after the beginning of my first run  characteristics. I then went and opened the Base Alignment Match and selected the points that i made. I actually have to move this part two times so i have two Base Alignment Match. I start the program and it runs fine. It gets to the first Base Alignment Match and instructs me to manually probe the points which i do. I then click the accept on the pop up window and it takes off to pick up the first point and it goes above the part +Z not even close to the point taken. Information on this will be much appreciated. If there is another way to program this that would be great too! Thank you.

I have not used base alignment match before. I would double check everything in that first alignment match the same way I would check to see what's not right with a base alignment. If you turn on "show probing object", it might give you a clue as to what's wrong with the alignment.

What do you mean by "i projected points on the features that i was going to use for the Base Alignment Match."

I don’t know what feature types you are using  but I would intersected points on a surface, I.e, cylinder intersected to a plane. Unless you remeasure the surface you are projecting to then you may have an issue. I believe your process is right but try a different way to construct those points.

I have a Z plane X and Y plane. These points from these features are exactly how my original alignment is and i chose these points exactly in order in the Base Alignment match. I recalled these planes to make points because the Base Alignment Match does not accept planes only circles and points. I then chose these points for the Alignment.

I am recalling the points to the surface of the planes i created. When the manual probing comes up it says to take the features as i do all three planes. It is getting lost at this point when i finish probing the features. The only thing i can think of is my Z plane that is below my other plane/point features taken it gets lost? It searches for and errors out.

I am sorry i should've included this to show how i am working with this. The Plane 35, i then recalled the plane to make Point 16, Plane 14 i then recalled the Plane to make Point 4 and the Plane 12 i recalled and made Point 3. In my Base Alignment match i chose them in this order of Point 4, Point 16 and Point 3. I made sure that these features are part of the first part of program that it picks up. So i am measuring these twice because the CMM already knows where these features are that i made for the Base Alignment Match. This is what is confusing me because it already gave me dimensions for these.

I think, that only three point won't be enough - at least 5 i would pick. 2 points for Plane35 ( one for each plane ) - same for Plane12 and so on.

RPS will use 6 points - so maybe here too. It's quite bad, that you can use only points and circles ( sometimes spheres )
Perhaps intersections of planes would work too.

The Base Alignment Match, after i put all the characteristics from original alignment like it says and select the Base Alignment match. Am i confusing myself here? Do i put the beginning Base Alignment points in the Base Alignment Match or do i put my second alignment points in the first Base Alignment Match. I hope i am not confusing myself or way over thinking this?

I got it to work with points, i used 9 points. I used 4 for Z, 4 for a Y and 1 for the X. I might have used too many points but this worked for me. I had to move the part two times with two Base Alignment Matches. I used my original alignment for a first move and my first Base Alignment match. Then added another for the second move. The part is 120" long, it was alot of points to use for this to work right plus making sure the part stayed flat when i made the moves. I am not sure if i will do this again but i learned how it works. We dont usually have these long of parts to check like this. Instead of using a steel rule like in the past how they checked the length i didnt want it to be this way. So now the engineers have numbers to work with. This part was definitely a challenge. I took the advanced Calypso class but they didnt show this then that i can remember, of course that was 15 years ago. Thank you all for the help with this, much appreciated.
