it doesn't really matter here, my question is more for my own education, I may only be a hobbyist, but it sometimes doesn't hurt to learn...
so as can be seen by the pic below, my surface finish sucked big time... lots of chatter... noisy as all get out too...
now, there were no finish passes, just roughing, as I dont really care about the surface finish here, but still am I correct in thinking that looks a bit rough even for a roughing pass
this was using:
Center Cut End Mill - 17mm
31810 - TTS M8 - Medium
tooling
at 0.100" DOC, 40% width of cut, 5100RPM and 43ipm
my uneducated guess is that is a lot of force on the relatively long tool?
I have one more part to do, would it be good to drop to say a 20% width of cut?
or could my inserts be getting dull or something? (if so, that would be great!!! be the first time I ever had a tool die of old age, vs a violent death! be a cause for celebration I would think?)
