Good job

👌👌👌👌

Im a qualified mechanic, but a CNC amateur/auto-learn, and i've a cheap and little 3+1 Axis to mill my own project and alluminium parts.
Every time i see your company at work and the brutality you use for mill your parts... all that chips fly around... your strategy in fixturing and all the other stuff.
It's always amazing man.

Boom.

As a beginner machinist i thank you guys for all these videos because i learn something new every time. Love you guys and love this trade.

I use double sided counterbored tabs (if the part is thick enough). Basically you can flip the part with the tabs on the outside of the profile. Then sometimes 2 tabs have pin holes that I rebore after the first op. It works great. The excess is removed in the first op. This way you show is all fine and dandy without flatness callouts. Double sided counterbored tabs keeps thing pretty flat and that "pre deburring" of the "bottom side" (op2 bottom) is nice. I have always loved having the bottom deburred because like you said cutting tabs off is really easy, if you still need to finish the profile you can. Since the deburred bottom allows you to stay off the fixture. A lot of guys cut in to the fixture. Most of the time it's unnecessary, just have a really sharp finishing tool so you aren't worried about tapered walls. I make my tabs where my clamps can be used after the tab is cut away. I try to show people it but for some reason people don't listen. Tabs are so powerful.

I would classify as an intermediate cnc Machinist. And I have to say doing tabs have always been a problem on my last job. Like accidentally stripping shoulder bolts on an aluminum fixture. Or the programmer didn't made enough clearance for the bolt. Then the same issue with dowel pins as well. Usually the spindle speed is off so the hole becomes a little oblongated. Then also the issue of flatness. Then yet again we didn't use a torque wrench.

The names of these videos... I mean getting a little conceded, maybe just me but chill

Dude I love mighty bites.
Hate when someone over tightens them

Love this fixturing method. Great way to use a universal work offset for multiple operations which eliminates the chance for human error and reduces risk. Great job Berry!

pretty cool ideas and technique

Nice tatoo barry 😁

Berry making it look easy! Love the editing on this too, awesome video.

Cool!!! Can’t wait to see the second op. I like that the drill also acts as a reamer. I learned something new today…..

Cool, BOOOOM!

wouldnt switching to titanium be a good idea for something like this , its a strong metal resistant to corrosion and half the weight of steel if im not mistaken

well i guess its probably like 4x-7x the cost

I would love to see more about those fixture expansion pins and how to use them

That is a sweet method. Looks familiar. Do you send it to the sheet metal department to cut the tabs? Haha Keep up the good work Love me some Barry!

Pretty cool technique for one off parts.

That's some shocking welding on that cast.

Tip flip it the right side as you have programed it (learned it the hard way -_-)

Killed it Barry, still the GOAT. 🐐🐐🐐

Definitely a slick fixturing method. The less you need to dial in the better your chance for success. Real solutions right here.

I liked this. Waiting for part 2

love being in this trade and learning every day

Wish to be a great cnc machinist like these guys one day

Great video,. Keep this guy on camera. Put him on more often. Good personality. Makes a watchable video

niceee 😇

I think this is the method proto labs uses

I see solid carbide seems to be tool of choice for roughing ally from the videos I have seen. Have u tried insert cutters before? Like sumitomo WAX for example. High centre clearance, high rake insert. Most brands have their own version, I’m sure kennametal would also.

Was the lookahead lagging a bit, or was it off? Anyhow, great fixturing technique!

looking forward to the second op

I've always thought this method was awesome but I never cut aluminum so using this method is difficult to justify in steel and tool grade steel

Was this video of the good parts or the first parts?😉

Best things I’ve started doing lately is making fixtures. Instead of playing the, “oh it half worked last time, it’ll go this time” game I’m making sure that next time it’ll only take a few minutes and I’m up and running a difficult to hold part.

I love this kind of work flow walk through! Keep these comming! Its like dropping by a buddies shop and learning a new trick!

NOT IMPRESSED. angle grinder with a cut off wheel could achieve the same thing

Love it!
