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.

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.

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.

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.

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. Thanks for another great video.

As someone who isn't a machinist. Could part of the problem be the way you rigged that L-shaped piece of stock out? The heavy end L-shaped end hanging out? I know you had something underneath it but, with the good review you gave the bit prior to filming this cut, and the way that the bit seemed to crack/break towards the end of the cut repeatedly. Wouldn't that indicate a possible slight vibration cause the bit to fail? Or was that the intention the entire time?

Hey dude, long time listener, never commented before. When i mill hard material i usually tend to go will a bull-nosed endmill, reason being the corner of the endmill is less likely to break and ruin the rest of the endmill. hope this helps

What about an abrasive cut off wheel? On a side note I cut some ar500 with a lake shore carbide 4 flute .032 round corner. I bored some holes for a guy to hang the plate to shoot at. I went really conservative on speeds and feeds. With lots of air mist.

1:00 yep there are the holes. This is definitely the same piece of ar400 he was testing drill bits on five years ago

Setting 76 will give you the option to turn off the tool release button on the controller so it’s just the button on the spindle. I have it turned off on every machine in the shop.

I had to drill 11/16 hub mounting holes in AR500 sprockets and it sucked donkey balls. I think I was getting only 6 holes before the cobalt drills cried uncle. That stuff just destroys the flutes and once the sides of the dtill start rubbing and squeaking you're 1 hole away from meltdown. Had to get carbide insert drills which work pretty good with high speed and slow feed.

Work with AR plate at the ol steel mill from time to time and can confirm it is a pain in the arse

Bought a chinesium spade bit what for drilling deceased tree carcasses and not only was it bananna like but the centre point was way oorf and induced much vibrations during drilling. Seems to me the material is not the main issue but a lack of precision manufacturing that causes bits to snap unduly.

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?
