I recall reading somewhere recently that too slow a speed leads to cutter breakage. Having just boobed and broken ( snapped) a 3/4 by 3 in long end mill ( I engaged the auto up feed by accident when milling some aluminium- took a BIG BITE THEN SNAPPED before I realized what I had done ).
Can someone Shed any light on this? Tom ???
I can follow why too slow a feed might lead to heat and blunting of cutter but too slow a speed leading to snapping?
Moral of story- don't rush especially when engaging auto feed. My mill can autofeed the table up as well as cross feed.
