It take me back to my apprentice days, it's all about feeds and speeds. I was milling j-preps for welding on a clapped-out manual machine built in Russia in the 60s, using a profile cutter with carbide inserts. This machine was design for HSS tooling. I got her running just happy (with the table locks hammered on to stop the leap due to backlash) and the Supervisor wants the speeds and feeds up. The tools instantly destroys itself and I get to take another 2 hours resetting the machine with a new tool.

[@crazyguy32100]

I've seen the table drive gear blow in a $3,000,000 transfer machine because management wanted it to index faster to increase rate. $85,000 in parts and 90 man-hours later it was replaced.

Way too much chooch, not enough chach. Surface footage is too high, and tool chipping is from vibration, the ole haas aint rigid enough to do what you're trying, gotta slow S&F way down. Member Chipping = vibration Burnt edges = too many rippems Worn coating = worn out lol Also, the reason for air over coolant is not just thermal shock, but most coatings actually have an operating temperature for best tool life, if you're running coolant it may never get there and will wear right off.

Look into G-Wizard for your feeds and speeds. You should be spinning at like a 970 RPM or so and a FPT of 0.002 for rough 1600 RPM and 0.0045 FPT for finish. If you feeds and speeds don't match your cuts you're wasting your time no coolant

[@Normjohanson]

Modern machine shop has bunches of articles on this topic.

[@TheWidgetWorks]

Surface speed to high, especially with chinesium tools. Probably would run for many more time units at about half that speed or less, other than that looking good. Also thermal shock from the coolant isn't that harmful, lots of tooling companies have done the tests and, except for some cases, it make very little difference and in a lot of cases it can reduce chip recutting with is by far worse than thermal shock (unless your running ceramics, coolant and them = pow! busted tools). In my opinion, coolant isn't a great idea is if you running really high surface speed (well over 1000 fpm) in steel/iron. Then the thermal shock can really be hard on the tool life.

Cutting hard steel with end-mills has been troublesome for me. I switched to insert milling and never been happier. Sure, those things don't last as long, but at least they're VERY consistent. I also use a Kolroy system that has part A and B for roughing so, part A will cut a certain height and B on another, Both blades are on the same APMKT insert, so you just have to buy one set.

[@leftyeh6495]

We have all our targets cut by waterjet. Any heat that discolors will actually soften the AR400, causing large crators when hit with the lead injection. We bolt everything to conveyor belt and just deal with a new bolt here and there, targets last a super long time given the ability to shed energy and move along with no disruption of the heat treating/hardness/toughness.

[@EdgePrecision]

To much surface footage for the hardness. When that tool gets red hot with the flood coolant you get thermal cracking. It would be better to cut dry.

[@neilbrown3359]

Uhhhhhhh, turn the spindle rpm down! The material your cutting is too tough for high rpms, I don't care what carbide tooling you use. With all that vibration a HSS endmill won't last long much less a carbide endmill

I've used those chinesium carbide endmills from AliExpress a few times. I've noticed that they have some bad geometry on the ends, which might be where your face milling pain is coming from. If you look at the bottom of the flute that would be cutting if you were plunging, they put a flat that is vertical as far as I can tell. No sharpness to it at all, with very little relief. Comparing that with my american endmills, they'll continue the helix down and not put that flat there, which gives the cutter more positive rake. These were endmills designed for aluminum supposedly.

[@vc1343]

The shop I work at has a rule: you wear it out; we replace it. You do something stupid: you do. So forgive my old school conservatism... But we work a lot of AR 400 plate... It does not take much imagineering failure to spend a weeks wage on bits. Chinese or otherwise. For surfacing I find a fly cutter is the safest, fastest way to get through the hardest layer at the most cost effective tool/time/set up cost. Finish is remarkably good too if you slow the feed rate down and take light passes.... 10 thou inc to maybe 40 as you get deeper. Another approach a buddy of mine uses is to simply grind the surface finish off by hand before machining. I tried it, and with a new disc it goes pretty quick and made a big difference later on the mill. The worst situation for me is when the cutting table guys give me an inch or two of AR that they cut too fast. Flame hardened holes, reverse draft angles, slag fused edges... Its honestly faster to cut and drill it myself... You have a beautiful machine there but AR plate is one material I prefer to work on the power assist manual machine when a sketchy set up or crappy rough cut part hits my bench.

If those edges are torch cut you will have better luck conventional mill through the torch slag, I know it's a cnc but conventional for that application. I used to heavy machine and am a Toolmaker currently. You need to get below the slag and you don't pull the slag through the cutter.

I typically just touch the tools off on the workpiece with a piece of paper and scribble down the tool# and the z offset. The z offset is almost always negative from the limit switch down. Hard milling is crazy lower feed use the wear resistance of the tool to eat away at the material. Try single profile thread milling die steel (enginerds and the hole locations they give)

I really like the helicals. I’ve found tool steels and harder steels we work with love that light and fast cut. Moment you slow down or go deep you butter the bird.

Why don't they use lasers to probe the workspace? Seems like at a minimum you could use several of them for roughly creating a 3D space to avoid breaking probes... Although I'd imagine you wouldn't need the probes at all if its done well?
