I work on equipment automation, the worst errors we get are intermittent.
One of my guys is working on a machine in Phoenix that manufactures computer wafers, we redid the robotics on it. The customer provided the initial program that we were supposed to modify, it had a lot of bugs in it that we had to deal with. The total overages were 280K on a 110K project that I had eaten, we reached a settlement with the customer and split the losses, some of the stuff was due to my guys not understanding, and some do to the bad program. I am OK with the settlement, and the customer has placed an order for more machines, with very defined scope that I should make up the rest on, and I will manage so we stay in scope.
This machine has a large (30 inch) carbon disk with five small (6") holes in it for silicon wafers. This is a lot like the old multi CD changers that had big disk with holes. The machine has to home the disk so the other robot can load and unload wafers. It would error out randomly about every 100 wafers. We had to devise a trap to look for these events and it caught the event this morning. We have to build traps sometimes when looking at a program just does not disclose the error.
We have been looking for this particular issue going on two weeks now.
