@hearkat I am not (nor do I really understand) “most people” though, so it still doesn’t make sense to me. I’m not saying you’re wrong, just that I’m not understanding a world I’ve never been a part of. One where limited function is okay so long as it looks fabulous_and even when you can have both. I don’t think sacrificing function for style, especially when you don’t have to, will _ever make sense to me.
To illustrate one difference between us though, you work a desk job. Take away your desk (including the PC), the wall clock, and the wall. How would you tell time at work? Would you reach into your pocket and grab your phone when your hand is covered in oil and aluminum dust? No, I think you’d wear a watch. Probably one that is either a bit on the tough side, or utterly disposable. But it’d have to have a countdown timer too.
As for the math, tell me the RPM and feed rate for a ¾” 3-flute end mill that will have a surface speed of 4200 ft/minute and a chip load of 0.006”/tooth. The formulas are easy, but I find multi-variable equations like that a bit much for doing in my head; it’s a bit more complex than calculating the tip on a restaurant bill. If you can do and IPM = RPM * 0.006 * 3
where RPM = (3.82 * 4200) / 0.375
in your head, you’re smarter than I am.
No, I think our different opinions here are due to us coming from vastly different environments, having different needs, and otherwise generally you not being me and me not being you.
