Chat with an old timer at the shop made me rethink my feeds and speeds
Was running a tough stainless job yesterday, fighting chatter. Guy who ran this machine for 20 years walks over, watches for a minute. He just said, 'You're scared of the machine. Let it eat.' Dropped my feed rate by 15% and bumped the spindle up 200 rpm. Cut like butter, finish was perfect. How do you guys approach a noisy cut on a new material?
