Squaring Issues

[JEL DESIGNER]

Lately I have been having squaring issues with our Torchmate 6 X 14 Table X. We cut a couple of pieces out of the same piece of 7 ga. The pieces are both 6' X 6' Square. I put the pieces together to get only 1 seam for the cross cut to make the pieces both 6' long. These parts were cut out of a 6 x 12 piece. The 2 pieces were cross checked for square and were foung to be a 1/2" out of square on one piece and the other was 3/8" out. I am not sure what is going on. Is there a procedure on squaring the table? I am in need of getting this figured out as our table is down and holding up our production. We have multiple projects that have to be cut and ready for our fit up welders. We have been doing the plate alignment feature when putting new sheets on the table. Is there a written procedure for that in case we have someone new that needst o run the table when our regular operator is off? Any help would be greatly appreciated in resolving these issues.

To check that the gantry is square to the table use the good ol' 3, 4, 5 rule.

Where do I do this from and to what? Is there a written procedure anywhere that states how to do this?

 

[Dnmeistr-LECS]

The 345 rule is used to check a triangle is 90 degrees. Measure down the length of the gantry 3', measure down the length of the table 4' and the two points between should be 5'. See attached this is for a TM3 table but the same principles apply for any table or any frame for that matter.

What is considered the drive side of the gantry? Which end is this going from? Is this done off the end with the fill valve or the opposite end?

Both sides are the drive side and from what end you measure from doesn't matter, you are not measuring from either end of the table. You are measuring the distance across the gantry and the distance down the length of the table.
