I work 15 feet from a station where they use giant lead sledge hammers to straighten out Harley cranks, on the other side of me are 2 5 axis machines that churn out ported cylinder heads. my machine will only make the sounds comming from the machines to my left or right if something breaks horribly. usually I phase out the sounds and listen to my Newen drone on but some times one of the sounds will sync PERFECTLY with me running my machine.
Only a cnc operator knows how fast you can hit a 1/2" button from 20 feet away without even realising youve moved
