I tested the Maritool brand of hard milling end mills. I think they are re-branded from HTC. This 1/2" EM cut AR 450 plate nicely, but vibration kills em instantly.
There are so many interdependant variables for optimizing feeds and speeds that you really only have one option to get it right: trial and error. The formulas, spreadsheets and software only
narrow the spread.

When I was doing a lot of programming at my last job I had a couple charts I randomly found on the confuser and I always started there. After running the tool I had a tool chart next to each machine that I would scribble out what I ended up going with in the end.
It’s important to keep tool charts for each machine too. Each one has it’s own character and preferences. Especially if they are different size machines.
could be that your tool is wobbling, because you used a torch for the shrink fit, it should be done on a propper device designed specifically for that, to get the optimum result. Bad runout eats endmills for breakefast.
I need someone to make a compilation of his funniest moments
I have found in almost 40 years of machining , the parameters the tool salesman gives you, are for perfect conditions. There are very few jobs you will have with perfect conditions. And they are in the business of selling tools, that’s where the money is at.
All I know is you need aluminum vice grips
Run it till it breaks then back it down 10% hahaha
So…are you looking for an apprentice?
Keep your tool holder in a tool holder holder
I guesstimated from your 1st cut , from sound, that it was too high rpm for sure.i guessed your spindle speed was at 2200 to 2500..you said 2000 rpm.. damn i was close
. i was figured slow rpm to about 1250/1350 rpm and feed of 8.0 to 8.5.. keep uppin the feed till chatter goes away .. been machining 25+ years and 1st thing i do is listen, then look at spindle loads and chips.. experience is the formula foe show. Programmers rarely get feeds and speeds correct on an unproven program, even if it worked for same material, same tool, same holder..there is always some contour or tool path the endmill just dont like.
You had her singing in a tune of D#, Mr Chreees!
Well Done , not many people have managed that for any length of time.
You are have no idea how you help us out on many subjects Brother.
Cheers & keep you dick in a vise.

Many comments on my videos people ask about feeds and speeds depth of cut exec. I hesitate or don't like to give this kind of information. There are so many variables involved here that wont be the same from setup to setup. I have even run the exactly same parts with the same tooling on the same machine that didn't work the same the second time (Differences in material probably). Everybody has their ideas that they think work. But the thing I have found is it generally wont work the same for you. Even if you have the same machine and same tools. You are going to have to experiment until you get it correct for your setup. The trick is to have enough experience to make the right changes and not to wast to much tooling and material. Thanks AVE!
