Im new to cnc mill programming and operation but have caught on pretty well. We have 2 brand new Hurco cabinet mills, a vm10 and a vm20. We have 3 guys that run the 2 machines on 1 shift. They don't run non stop, they probably sit more than they run. We are a prototype shop so most jobs are just a one time run. Anyway, I'm trying to implement a tool library and i am wondering how other people approach this? We have a "library" within our programming software but whatever is in the machine isn't always what's in the software library for that tool number. Im just trying to come up with something simple we can agree on and follow. Also, do you guys use re-grind cutters and if so how or you implementing those into the mix? Just looking for advice, oppinions, feedback or whatever you can offer.
