PSA: a new guy asked why I still crank handles by hand, and his reason made me stop and think
Had a 20 year old kid on the floor at our shop in Dayton ask me why I bother turning handles manually when the rapids do it faster, and when I said "because you feel the cut" he just nodded and said nobody ever explained that to him. Made me realize we spend all our time teaching codes and offsets but skip the part where your hand tells you the tool is about to chatter before your ears do. How do you all get new operators to actually feel what the machine is doing instead of just trusting the screen?
The whole "trust the screen" thing is only half the story though (the screen won't lie to you, but it also won't tell you when the insert is getting dull or the material is harder than last batch). Your ears and hands catch stuff the readout never will, like a slight jump in the load meter or a sound that changes pitch halfway through a pass. So yeah, teach the codes, but get them on the handles early where they can feel a good cut versus a bad one before the part gets scrapped.
