Blue chips
#1
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?
Mike
