Hello everyone.
I have some issues with getting the feeds and speeds dialed in with end mills. I am running a 1/2 TiALN Coated Endmill in 1018 steel. Our machine is a NL3000y mill/turn center.
I was running the end mill at 220 SFM, 0.0035 feed/tooth, recommended by local supplier. Full length of cut (1") and a .06 step over. After the first part, roughly 40 minutes of work I was seeing a dull edge and tiny, tiny chips on the flutes already, coating also seemed to be showing signs of wear. What are the first adjustments I need to make to prolong tool life?
Also - if I make the switch to 1045 material, how much do my variables need to change?
Thanks everyone for your help.
