I added a basic module to the new FlexIO program this week to assist in detecting moved XYZ tables. After a frustrating day at the office, I came home, had a few beers and came up with this solution to try and fix my problem for the next time. A common problem I faced was after a drawing had been created for a part, the actual part itself had been moved in virtual space. Then when the bend file had been created, the tables were completely different because of the move. Because of this, how to correctly determine if the table is actually correct, or if there was an actual geometry change in the design that had been overlooked?
The module I created just looks for simple X/Y/Z direction movements, it gets a little more complex when looking for parts that have been rotated in 3D space, so the model doesn’t look for that yet. It works by asking for the first row of coordinates from the drawing, and calculates the differences between the X/Y/Z in the bend file. If its just a case of simple movement, the offset is applied to the remaining points and the new table when updated will then identically match the drawing (if there is no geometry change). If you start seeing some points being a little off, you can check in CAD to make sure there is no rotation, and put the difference to being a design change which requires the original part designer to submit a revision change.
It’s a start, and saves me a lot of time when verifying a large number of drawings at one time. Still lots of other verification code to add to other areas of the program 🙂
