CNC machining a custom nut | Hermle C400 | SolidCAM | iMachining | trochoid | TPC

Just Machining - 03
In this episode of "just machining" I machine a custom-made M13,2x2 nut out of AlMgSi1 (3.2315)
To get the material roughed away I use a plunge mill followed by a 4.5mm end mill running on an iMachining job with a high feed for that little cutter.

thank you! and yes it is really not the smartest thing to cut aluminum dry, but for the video it looks better :)))

[@3073Sean]

Bavaria - I LOVE your machining strategies. I learn a lot and have adopted some of them for my self. Thank you! One question, what is the width of the tab you leave post slit saw?

[@BavariaCNC]

Thank you! This is good to hear! The leftover material is 0,1mm after cutting (0,004")

[@chongsiu7893]

@@BavariaCNC Are the tabs located off-center so the part would lean away from the saw as the tab gets really thin, or is that not necessary?

[@BavariaCNC]

@@chongsiu7893 It is not 100% necessary, but it will help for a nicer surface, if the part is getting heavier you will have to increase the thickness of the left material

[@chongsiu7893]

@@BavariaCNC That makes sense, thank you.

[@varadero311]

Really efficient program ! How do you clean the backside to reach a proper surface finishing and get rid of the little flange ?

[@BavariaCNC]

Hi, the backside i did just some sandpaper job on. On the inside I missed to film one chamfer job with a dovetail end mill =)

[@gcbefree68]

Sehr schöne Videos von euch, Kanal ist abonniert! 👍👍👍 Habt ihr auch eine Minimalmengenschmierung an der Hermle? Da würden sich die Schneiden nicht mehr so zusetzen und man kann trotzdem was sehen. Klappt an meiner Haas sehr gut!

[@BavariaCNC]

ich hab leider weder an meiner hermle noch an meiner Haas eine MMS aber ich bin dran mir was zuzulegen 😊 im normal Betrieb fahr ich natürlich nass aber fürs Video ist das dann ein wenig Zuviel Wasser :)))

[@jonijoni12345]

Top Video 👍🏻 warum benutzt ihr hauptsächlich unbeschichtete Fräser?

[@BavariaCNC]

Komplexe Frage ;) primär weil ich den großen Mehrwert von beschichteten Fräsern bei meinen Einsätzen hier nicht erziele, Drehzahl ist auch jetzt am Limit und Späne gehen gut weg. Da wäre der Mehrpreis nicht immer gerechtfertigt. Außerdem bin ich persönlich der Meinung das unbeschichtete Fräser im Alubereich nen Tick schärfer sind wie beschichtete, aber das ist mein persönliches Gefühl ich könnte die das nicht beweisen.

[@fabianbrock]

Did you cut a second batch of parts out of the rest of the stock? Just realized that there would be enough stock left, if the tools can reach it without touching the vise.

[@BavariaCNC]

yes I did that, I even start with an extra layer before

[@fabianbrock]

@@BavariaCNC That's clever and once you see it, it is so obvious (or maybe it is normal for you professionals). Great way to get more parts out of one setup.

[@danielredmayne6956]

Great 5axis vid. But im sure lathe with live tooling would be so much quicker to produce?

It was difficult to get a sense of size. And now I’m watching all of your videos. Amazing programming, amazing machine, amazing camera work. Thank you for sharing!

[@VictorHernandez-nt3tw]

Nice video. When you program this and start the next 4 PCs. At the different height, how do you program it? Just different offsets and copy and paste that program multiple times using different offsets?

[@BavariaCNC]

at which part of the video you mean that?

[@VictorHernandez-nt3tw]

@@BavariaCNC it wasn't in the video. I just though with the extra material you had, you would get a tall piece of material and keep repeating the program to cut more parts with the same material

[@owievisie]

Really nice I feel like I'm one of the few who chamfers a hole before tapping What is the reason for tapping and then chamfering?

[@BavariaCNC]

i do it this way as I want to ensure that the tapping won’t make a burr and especially cold forming will make burrs for sure

[@ShInYaKu88]

i am drilling, chamfer, cold forming and then deburring. if i dont put on a chamfer before forming, the former will pull out some material and then deburring it not enough to make a great flat surface around the thread... :D

[@hanswerner6882]

would be more scared off pushing in a burr with the chamfer tool. Not a problem in aluminimum but on harder steels like 1.6582 its another other deal

[@BIGOS-CNC]

[@Grazy1967]

da würden mir Einsätze in SAW Filmen einfallen, Nein Quatsch, ich finds Toll, ich hätte gern so Maschinen als Spielzeug - leider fehlt der Platz und ein bißchen was anderes ;-P und eben erst zuende Geschaut, ich bin leider seit 2006, wegen Krankheit, raus aus der Materie aber fressen sich heute wirklich immernoch Werkzeuge voll an Allu? (vielleicht heißt das heute anders aber so sagten wir halt) oder lag das nur an der fehlenden Kühlung?

[@BavariaCNC]

Platz und Strom gell ;) und ja alu ohne Kühlung ist schon schwer aber fürs Video Versuch ich’s immer weil mit Wasser siehst du halt leider gar nix

Right now I dont have that. So i pre lube for videos.

[@marekchilinski2259]

There was 2nd OP after as there is no chamfer machined on the second side of the main thread and surface after cutting off by using saw cutter doesn't look as shown at the end of the movie :)

[@BavariaCNC]

Hi Marek! You are right, I missed that tool on the video, it is a "simple" 45° dove tail end mill that I take for that befor cutting the part off ;) You have a good understanding of the process.

[@briancr1934]

What causes the bottom few mm's of DOC on the surface finish to be matt compared the top of the DOC?

[@BavariaCNC]

I think you mean it for the first roughing tool. Here you can you which part of the tool has been used a lot and which not, the lower 5mm are used probably 10 times more often then the upper rest, so those parts will cut better.

[@briancr1934]

@@BavariaCNC Thanks for explaining, I was wondering what caused this effect on my parts sometimes. Looks like its the slightly worn tool tip then

[@BavariaCNC]

@@briancr1934 this is one of the reasons why you will see in some of my videos that I use the same tool twice. I use one for roughing and the other one will only do the finishing job. As soon as the roughing tool is done the finishing tool will become the roughing tool and so on.

[@frp1276]

Occasionally spraying coolant just makes chips stick. Use through spindle air instead. I also can't see any reason for the initial roughing... I'd just use the roughing end mill from the start.

[@BavariaCNC]

I don't have through spindle air :) You could also only use the end mill, this is correct, but I really like to do the first plane job to ensure there is no mistake in the pre cutting. The end mill is pretty small, and even some variations here could easily kill it. So if I already have the tool in the machine, I could to the roughing as well.

[@OldCarsAreFun]

In the outtakes does the machinist stop the tool or the mill itself?

[@BavariaCNC]

it was me :) the machine could stop on a tool break, but only if the spindle power for the tool while cutting is around 10% otherwise it can’t detect it

[@OldCarsAreFun]

@@BavariaCNC Ah okay, of course, is to small of a change in spindle load. I havent used the function yet, I thought it was more senitive, that it also could detect worn tools?

We have a guy at work that says CNC mills don’t make money and 5 axis is a joke.
