Here is a revised calc based on .125 DOC, and .350 width of cut. The feed rate is 4.4 IPM at 745 RPM, requiring 0.11 horsepower. I too suspect your gib adjustments are too loose.

Sep 09, 2014 · Speed and Feed for Carbide Endmill in A36 Steel 09-09-2014, 07:46 AM. I have problems with my TiAIN coated endmills meeting a premature death with my CNC Bridgeport mill. I use the G-Wizard feed and speed calculator but I end up having to back off the feed because the 2hp motor just starts to struggle. Cutting is dry and once a lot of sparks Steel Feeds and Speeds - Practical MachinistMay 13, 2006 · 1018 is the "base" steel around here. It is 1018 in cold finish, and called A36 when in hot finish. (I'm sure that they are a little different in composition, but for all intense and purposes, they are the same) 4140 H.T. is my favorite steel to machine, with A516-70 about second.
2. Adjust RPM & Feeds after Setup to achieve Optimum Tool Life. Use Higher Feed Rates in Soft Materials. Horizon Carbide Grades are Designed to provide Long Tool Life at Higher Speeds and Light Feed Rates. Formula to Calculate Surface Feet Per Minute (SFM):SFM = 3.1416 x Part Diameter, Divided by 12 x RPM HORIZON CARBIDE TOOL, INC.yeah, so we have some A36 steel pieces, pretty small. Only using drill, 3/8 carbide endmills, and 1 small (.078) endmill. It seems to cut worse andget better tooling or check the feed and speed we cut a lot of this stuff , basically it's the same thing as a 44W plate or 1020 steel we never gotA36 should cut like butter. Don't let your SFM get to high and keep the chipload up. For the 3/8 Drill (depending on the MFG) I'd run it around 300Do you have a specific problem, or is it just generally bad.

I've run 60 or so parts, but not much material removed. I'm thinking they should last longer, maybe it's fine. Don't like the fiCrappy material = bad finish Crappy Scale = chipping your end mills Don't think your going to get good finishes or better tool life unless this isIs your material sawed out or torched from a larger piece. What we get here is all torched out of a larger piece of plate. All of the torching hardSaw cut from round bar, no flame cut. 2-op part in the mill, not much to it. It just doesn't seem to be cutting as nice as i'd like it to.That's weird I have that same problem with every job I've ever touched!!! Got some screen shots?

- 1018 Steel Speeds And Feeds For Milling With End MillsMilling Speeds and Feeds Charts The most important aspect of milling with carbide end mills is to run the tool at the proper rpm and feed rate. We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.
