Talk about fun loading this in my truck off a loading dock, and then into my garage with only two pallets, a two wheeled handtruck, and a ratcheting strap. It's still mounted to the pallet, but mostly cleaned up, and the bearings were broken in last night.

Today I got in my basic tooling: 6" horizontal Phase II rotary table, some collets, 2 and 4 flute end mills, parallels, and a few other little things.

I'm still waiting on my 4" screwless vise, and clamping kit.

I have a few other things I need to pick up in the near future, fly cutters, slitting saws, boring kits, etc. I think this will give me a good start though.

In any case, does anyone have any recommendations for tweaks or setup beyond the basic clean, lube, backlash setup?

Also, is there a good online source for DOC and speed settings for different materials/cutters?

doc a good rule of thumb should be half the diameter of the mill you are using as for feed and speed it all comes down to the material and how the machine takes it also the type of cutter you will use (carbide, coated, hss) and the number of flute on the tool.

this next chart should help you out

so to calculate your speed the basic formula is
(4xsfm)/Diameter of the tool (if you work on a lathe it will be the diameter of the part) = rpm

now to calculate the feed its
chip load per tooth x N of tooth x rpm

so lets say you have a material that as a sfm of 200 and a tool of .5"
(4x200)/.5" = 400rpm

so you feed is if you have a chipload per tooth of lets say .002" and 2 flutes
400x 2 x.002 = 1.6"/min

but remember all those are affected by the size and power of your mill a 2.5tons mill with a 7hp motor can chew alot more material the a 400pound mill with a 1hp motor, the same goes for the quality of the tool.
those will also affect the longevity of your tool since using the max feed will get the job done faster but will also kill you tool faster
