Quite a process though. Imagine there was a production run and they got the settings wrong on the lathe. Back to square one!
They wouldnt, what they tend to do is do a dry run first without any material (to make sure there are no completely wrong settings that could break the whole machine) then a second with the material, which then goes through a series of tests to double check everything is as it should be. If not, the process is started again, so they dont really lose out on a lot of material during this stage.
I think you took me a bit too seriously here....................well it is Sunday morning
Yeah i just got that
