I understand that blue chips are not a good thing; something is getting too hot.
Rockwell vertical mill.
Cutting 1018 cold roll steel. 1/2 inch, 2- flute, HSS end mill, end cut ~.015 deep, .250 - .375 wide. Hand feed, tried both fast and slow. ~800 rpm
Do I need to slow down the mill, slow down the feed, speed up either or both? I also tried a 4-flute mill with no discernable improvement.
Where am I going wrong?
