CNC Machine a Hot Iron Brand! WW152

[@bluedeath996]

I like this style, with the split screen showing your feed and speed settings as it's going. It makes it much easier to understand the effect of the options. Only a couple more months until I start my machine shop, thanks for all the inspiration you have given me.

[@beamerweb]

Hey John, Great video. As soon as I saw this, I jumped ... I started a business making branding irons out of brass just like this. We discussed having you make me some handles a few months ago. Anyway, the trick to those tight inside spaces and internal corners is not smaller endmills -- the trick is with a v-groove bit like a Whiteside 1541 - I haven't tried to do this in fusion 360 yet, but the rep told me an engraving toolpath would be what i want. I use vectric's vCarve Pro to do the toolpathing - all I ever need is a 1/8" endmill for roughing most of the stock away - then the v-groove bit does the rest. Hopefully I'm not giving away my trade secrets here, lol! I did a few videos on my process, but I won't spam your comments with links to my vids right off the bat. I don't want to be rude :) I'd be super curious to have you walk through this in Fusion if you get it working. I haven't learned enough Fusion yet to be good enough to switch, just yet. Thanks for all the awesome vids!

[@RobiSydney]

I use a 1 flute 30 degree engraving bit to clean out really tight spots. It's a HSS tool, so I basically use 1 per job, however they are really cheap.

[@shammient]

Jason Beam Same, I use a 60 degree carbide v bit. Vcarve also.

[@jordanstark1037]

Third vote, same here...VCarve is king for something like this... Leaving material on top to allow a final surfacing pass for cleanup of burrs at that size is a good thing too...can't beat the surface finish. If the part is small enough, cleaning in a reloading (ammunition cartridges) setup might help without ruining the crisp edges too much.

[@RambozoClown]

"Everyone's a hero in brass." So does that make everyone a superhero in aluminum? ;) Great video. I also use the vee type engraving bits for work like this. Usually in carbide, and you can get a variety of different angles and tip diameters. I believe these were developed for the printed circuit board industry, so they are crazy cheap. With a single flute slight runout is no big deal, but you need a metric assload of RPM. I bolt on an aux spindle with 25,000 but I would like even more, someday. Check out the 3D engraving tool paths. Easy to get near perfect square inside corners with a pretty robust 1/8" tool. The walls will be tapered, but for something like a stamp or brand it's usually fine.

[@patricksullivan9951]

John, a pleasure meeting & chatting with you at the Bash, what a great event! Love the video work, you seem to have really grasped the way to display what you are doing with excellent graphics plus good audio! Now I have to check out Randy's site to see how this works! Well done!!

[@bcbloc02]

Good tip on the need for progressive tolerancing in the Cam. Brand looks great and I saw it work live on the livefeed so great job!

[@stargatefred]

Another great video John. I really enjoyed meeting you at the Bash this last weekend. Thanks for all your help! Bill from Seattle

[@TMCmakes]

i really like this new style, where you show the machining with the inlaid fusion 360 screens so we get to see the chips fly and hear about the settings you're using. keep up the great work!

[@patrickmcclintock7027]

Your videos just keep getting better and better, man. Fantastic. And a really cool part, to boot! I love brass.

[@bgwmachine]

Great Job John! I haven't really watched any of your videos for a little while and really enjoy your overlay of Fusion on the live video. If I ever do this on my youtube journey, just know it was because you did it first! lol Keep up the great work.

[@RRINTHESHOP]

Great video John. Thank you for the help, it sure worked wonderful at the Bash. Thank you again.

[@danmetzger5583]

My BarZ Square box was the first one branded at the Bash. Two different vidsof it.....one was shot by "AvE"! Nice to get to see it being made. Good to see you too John!

[@RoboCNCnl]

Nice video John... I do branding irons to (even had a video on it this year) but I always use V bits, never bother with the small tools.. You should try it sometime... Works great..

[@GregsGarage]

I love the editing style with the screen graphics over the milling video... As for the last chamfering op... Could you have used an engraving operation on the letters that are too small? The V bit could hollow out the tiny areas, so at least the branding would be clear in those spots... Just a thought... Been using the engrave strategies A LOT lately for super small details.

[@Ughwhatevs]

Great video, John! Accidentally learned why one of my tool paths whisper cuts!! Now I can fix it! Thanks!!

[@AndTheCorrectAnswerIs]

I was surprised you didn't use engraving v-bits as others have already mentioned. I too usually use a 1/8" or 3/32" endmill to rough out and then have a selection of 10, 20, 30, and 45 degree carbide engraving bits that I choose from to do the rest depending on the level of fine detail. I would love to have a precise high speed spindle for the engraving tools and have considered adapting one of those Chinese 20k rpm water cooled spindles onto the mill.

[@JF32304]

Always nice work, John. Couldn't you use a .010 end mill for taking care of the 'R'' and 'B' slower but you'll remove the material.

[@toytimeyota]

I have used my Lakeshore (obviously other brands will work) engraving bit. .020" ball 20° Taper to get inside of the little areas on brands that have lots of detail. I use adaptive clearing and only cut about .030" deep. It takes a bit of time but works great on brands for wood. That was with an aluminium brand, brass would work even better.

[@MCEngineeringInc]

Cool part! I have done similar work. Take note of the letters and a slight tweak to the actual geometry may allow the tool to work. Chamfer tool is a good compromise.

[@andydix6243]

Like the split screen and voice over format. Makes it easier to see the connection between the cam and the actual machining. When in Excel though, can you zoom in on the cells as the rest of the screen isn't of interest. I watch lots on my phone so small text up in the top left corner is sometimes tough to see.

[@BluesDoctor]

Great videos as always. Begs the question when you might tackle micromachining? I learn something new in every video, always appreciated.

[@JackDanos]

Thanks John! I couldn't figure out why Fusion was making those weird "whisper" cuts when rest machining but now I know!

[@andyb6622]

I've built a few brands over a few years and withe the really small end mills you only need to go down .05" wiht them you don't need to go all the way. so rough .180 with the bigger end mills and then on down a small distance with your tiny end mill. sometimes you can use a really small ball to get into corners as well

[@terrydj5168]

Thanks John for all your great videos, learned a lot about CAM using Fusion 360. However, as a beginner, I am not sure how to set up feeds and speeds of the machining tool path. Also, is there any way to calculate the depth of cut and optimal load of the tool path? For example, I am currently working on micro-machining acrylic with a 0.5 mm 2 flute flat end mill (spindle speed:27000rpm, cutting feed rate: 720mm/min), what is the safe depth of cut to make?

[@lorenzotosato]

Great video. Spectacular video editing.

[@tsw199756]

Welcome to my world. I just finished a 3d lettering job. 30 individual parts and none of them were repeats. .045 high raised and drafted letters, .156 height, 15° draft, no fillet at the base. Just a small part of a much larger job. Machined from Grade 40 Cast Iron. Closed letters and small tools to clear them out is a real PIA.

[@jwmachining5955]

Thanks for the explanation of the "whisper" cuts. Very helpful!

[@ginakaraba4439]

What is a good program for artistic designs and even negative space engraving? I need a very small unit for making custom wax seals. Ive been searching for a few years to find a good brass engraver for 15-30mm blanks...

[@occamssawzall3486]

To avoid your dislike of constantly increasing stock to leave instead of doing roughing, smaller endmill roughing, etc etc. Rough with the largest and finish the geometry that the large tool can reach. THEN move on to roughing with a smaller endmill, then finish, and continue on that way. This way "previous op" is already finished to the final dimensions, and your adaptive with the smaller endmill won't pick it up as uncut material, allowing you to make the smaller endmills stock to leave as small as you want.

[@7711gman]

Nice! I use v bits to make irons. Gets all the detail. You don't use a brand very deep, just the surface counts.

[@OriginalJetForMe]

So, I often see those "whisper cuts" when I'm doing a straight-up 3D adaptive tool path, where the only thing that came before was a facing pass with the Superfly. In that case, I don't know how to adjust the tolerance properly. I have a tolerance of 0.1 mm, and a stock to leave of 0.5 mm, and assuming 0.0 stock to leave on the previous op (Facing op), that meets your formula. I think it's doing whisper cuts on the roughing passes earlier in the same op. I think it might help to adjust the Ignore Cusps setting (in my case, it's also 0.5 mm), but I don't know which way. It also seems to pick up the tool and rapid to the other side of the part, only to do the same and return to the first area to do a little bit more work. It's not super efficient :(

[@chadshort9231]

If you have a machine with only 2400 rpms available, how much difference would there be in S&F? I have a person asking form almost the same project but using stainless instead of brass.

[@regalcnc2438]

Very Cool!! Thanks for sharing!

[@letsfitindians7687]

hello sir i wanna know one thing that can we made this job with the help of powermill like this strategies cut side to side

[@Crip2Knyght]

Out of curiosity how much do you charge for something like this?

[@Warpfield]

Could have implemented a 60 deg V-Carve into the design to deal with the tight corners.

[@jimsvideos7201]

Now you know perfectly well that the machine is making very precise moves even when they're large moves, but watching the chamfer op there really made the point obvious.

[@aonemarine]

come on John, break out the .010" end mill. 10k .003 doc, .003 woc 3 ipm and have at it. I can do it on my g0704 with a router attachment. :)

[@JohnHolmestheSecond]

nice work Every time I see you use fusion i see features that are fantastic and make me want to use it. Then I see those bizarre litte bugs and decide no thanks.

[@RobiSydney]

They're features dude! I have used F360, and I have generated tool paths. I must say there is a steep learning curve before you get good with it. I'm not there yet.

[@tonylorentzen]

Is it just me or can you actually see the tool deflecting when you're cutting with the 3-flute 3/16" ? :-D

[@RambozoClown]

Looked like that to me, too. But I think he mis-spoke and that was a 1/16" tool.

[@tonylorentzen]

You may be right :-)

[@occamssawzall3486]

Tony Lorentzen I think it's the reflection of the tool off the part playing tricks on you.

[@ajtrvll]

"Everybody is a hero in brass"... I heard Tom Lipton says the same about aluminium.

[@ReRamp]

Oh snap! Its already Wednesday!

[@urgamecshk]

I get the teaching, but a V bit is king. Those letters look fragile and probably took a lot longer then needed.

[@stormbringermornblade8811]

that was a great w/w :)

[@letsgoBrandon204]

Wow at this scale classical mechanics breaks down ;)

[@LarryRPark]

It looks like the brand needs to be tumbled or blasted with a fine media to remove all the attached chips. Maybe the face lapped on some 600 grit sandpaper?

[@royreynolds108]

He usually brands wood.

[@Warmachinellc15]

Yup as has been said. V-carving is your friend with brands. Remember this one? kzbin.info?o=U&video_id=jVowx2MizKQ

[@earth111]

Beef calories are the most productive, don't take my livestock! Therefore a brand must be created

[@BMRStudio]

uhmmmmm I lost in the path-chipload-ofset- tolerance calculations :) I'm alone noob like this?

[@ManofCulture]

i'm this early

[@gredangeo]

Alright, I'm in the Under 1000 Views club.

[@gcardinal]

This illustrates exactly what bad software can force you to do :) There is no easy way in Fushion 360 to do positive engraving - only very basic negative. Especially of this size. And no way to efficiently make use of larger engraving bits. Its sad to see what sponsorship can force a man to film...

[@JackMayhoffer]

Really? Fusion is geared more towards mechanical type of design not artistic. For that, a program like Aspire or Vcave are great but they suck at what fusion does.

[@schwarzarne]

So what are you complaining about? Everything gcardinal wrote stands true. There is software better suited to this job, as you admited, and if there wasn't that sponsorship that better suited software might have been used.

[@dannooo548]

Arne Schwarz It's not just sponsorship, it's experience. A guy who spends his life doing adaptives and threadmilling doesn't want to learn a new program just to make 1 part.

[@theater40]

whats revolution per minutes? you mean RPM?!?!?!?!?! sorry man love your vids but can't stand rpmssssssssssssssssssssssssssss

[@bigkenny66]

you could go with AvE's terminology and use RiPeMs
