My fixtures are as squre to the machine as the bolt pattern on the granite. In cases where it needs to be in better I use the ruby as an indicator so to speak to squre a part in. I do not indicate anything in.
We have a bar that runs across the front granite bolt pattern of the table. If i use a fixture i'm usually running multiple parts & have a loop in the program, but i always set the fixture up the 1st run...always
sigpic.....Its called golf because all the other 4 letter words were taken
I use a Rayco plate and fixturing system so like Craiger my stuff is pretty square by default however I do have a few programs that I use adjustors to get offset datum -A- locations as close as possible.
On a part that it is possible to square up, I square it up. I use the bolt holes in the plate for most stuff. On stuff that needs to be better, I have a section of code that I copy and past in. It prompts you to measure a line and if the vector is too far off, it prompts you to rotate clockwise or counter-clockwise depending on how far off the vector is. Then it goes back to the beginning and you do it all over again. Doing it this way I can get it so the vector is .99999 or greater.
Dang it! He suckered us all! I think the key was he found an old thread with only the opening post. I even looked back to make sure it was current. Must've only looked back to the second post.
So Im working on a fuel cap door, in a fixture, and im having repeatability issues. Im using an sm25 scanning head with a probe change to the TP20 midprogram....
