There are plenty of ways to crash your machine, but you have to remember: CNC machines don't crash, operators crash them!
Machining parts is easy... work-holding is the hard part! Fixturing, part setups, and work holding is a never ending skill. Any time I have the chance to tour a factory, walk a trade show, or talk shop with another machinist, I try to learn as much as possible about workholding.
We had the pleasure of having Keith Rucker attend one of our NYC CNC training classes. Keith is a great guy who does some impressive manual machining. We asked if there was ever a collaboration project we could do - especially where we could use our Tormach PCNC 1100! He said that it was perfect timing, as he volunteers at the Georgia Museum of Agriculture where he's helping restore a locomotive!
I love automation – there’s just something about watching a robot making parts you’re going to sell. A machinist friend of mine (Hi Peter T.!) refers to his bank of older CNC lathes as his money printing presses. They sit there with their bar pullers grinding out parts for him to sell all day long and about all he has to do is change bars and inserts from time to time.
