Loved seeing the difference the coolant made. Aluminum cuts like butter, so fun! This is where CNC really shines, I could make that parking attachment arm for Abom on my manual machines but no way I could make this. In the old days this would have been hand work to finish out, better give this job to Tom Lipton and his files. :-)
A fun future Wed. Widget might be to redo this using 4-axes on the 1100 and then re-fixture to get the remaining sides... Also, design some wheels in F360 and leave some material in the wheel arches to mount them. Thingiverse is mostly stl files although there is some cad files. Most of the stuff on there is too highly detailed to work well in F360... In order to get thingiverse models to work well w/ F360, I usually find I have to first load them into Blender, decimate them, and load the modified model in the F360, unfortunately the process causes much of the detail of the original model to be lost.
The fact the surface finish transition is dead smack down the middle of the part makes me think that it's less the effects of coolant , and more the effect of up vs down milling with a BEM. The first half was all up milling, the second half past the midline was all down milling A morph surfacing path starting from the bottom and ending at the top would have produced a more even finish, or setting the parallel path to up cut only.
We build and manufacture 3d printers and are learning about milling etc... I loved your section on 3d model repositories. Your excitement for Mcmaster models is our excitement for thingiverse or cults3d :)
A lot of that memory size is due to details that you don't need in the model to cut. That's why i first open these in Sketchup and clean everything that isn't in the cut "sight". That lightens the file a lot.
3d printing cad files along with what you present here are just a superlative bridge to the more advanced make-files we will use when we finally develop nanoscale universal assemblers. More people every day are discovering that this downloadable bits-to-atoms means a radical departure from business as usual. Perhaps we can even transition from scarcity based economies to valuing the aesthetics of design in the competition for designs which comply with the users' every criteria instead of the dictates of the "broadest base of customers".
awesome, just awesome!! This is very informational and really good advice for an aspiring CNC artist like myself. To say it's that easy is slightly unrealistic, you have to have the right mindset for this type of trade. So many young people do not realize the importance of CNC and engineering. The experience gained even from a production shop can feed you enough knowledge to be able to work anywhere, making anything!!! I'm excited every time I make a good part.
about your 10% stepover if you are using a carbide cutter you will get better results (surface finish tool wear) if you cut with a greater percentage. i dont have any of my reference materials here at home but the company you buy carbide from should have recommended chip load/depth of cut chart of some kind. my company has drastically decreaced cycle time and tool wear, our representative from ISCAR will even help with troubleshooting sometimes.
Turbo squid is the largest 3d model download site for graphical representations, not so much for mechanical/ tolerance correct parts. Yes, CB 14 there was little/no lubricant in the water or it looked like pure water anyhow.
Great idea machining something fun from GrabCAD! The first thing you should have done with the model though (and almost all IGES files) is jump into patch and make it one body. You can tell it's a patchwork from its coloring. Also you're making the setup triad way too difficult. Click the base of the Z axis (or any axis) and then click a face perpendicular to the way you want it or an edge in the direction you want it. Going the wrong direction? Click the head of the arrow.
John, enjoyed this video and all the ones I saw. I'm diggin in your old content and really like it. I can see your travel to where you at right now. You're an honest, clever, hardworking guy who get's things done. I think you're a real person who I like. No bulshit; have a goal and go for it and don't change personality. Thank you for this. This was the feather to go where the sun doesn't shine ;-) My question; what does the Tormach costs? Just curious. Thank you for answer and all your great uploads. Stay safe, stay cool and keep up the good work. Best, Job Kneppers, the Netherlands
Very cool. I would love to see you try one on a 4th axis so you can machine the sides! That Lakeshore Carbide 3/8 ball endmill is awesome. I use those in machining mold cavities. I get chips that look like fingernail clippings from Fusion 360 adaptive roughing.
Hi John, as always - great video. Always learn something in your videos. Your shop and tool show tours are awesome too. The canned TH-cam music could go in the trash - just my opinion 🤗
Hey just wanted to say thank you for your content. I just started watching it two days ago and the amount I have learned is crazy. Do you have any recommendations on books for beginners? Thanks again! Looking forward to your new content!
The problem with Thingiverse is that most of the models are STL files. I don't know of an easy way to translate from STL to a solid model suitable for manipulation in CAD.
Regarding that I have an additional question: Why is climb milling used for the hogging cuts when surface quality isn´t necessary? The tool edge runs into the material full depth, while running into an angled surface would be much easier for the machine and reduce chatter. I noticed that on the parking attachment vid already where the long cutter had chatter problems. For a nice finish climb milling is better, no question, but for hogging?
+sthenzel Climb milling creates a chip that goes from thick to thin. Conventional creates a thin to thick chip. The heavier initial engagement in climb milling is easier on the cutter and the machine, takes less machine ponies to climb mill. And you get about 30-50% longer tool life from climb. Plus with adaptive its entering the material in an arc and maintaining a chip thickness and minimizes radial chip thinning. Which cutter life and cut stability. Read Bob Warfields article Climb vs Comventional Milling on the CNC Cookbook site. He does a good job explaining the pros and cons of each and why.
Do you even tried a tapered ballend mill? If i understand it right they would be a better choice for the kind of details. *i might be wrong*. Anyway.. don't you ever model up your vise? Or set up complexer runs in Fusion? I have tried to do some fixture cam in fusion but ran into a wall with it. :|
I've heard you talk about the classes, just wondering what the price for a weekend class would be? I am in the machineing industry right now to learn, but I don't want to stay in it. I want to have a shop on my property where if I need something I can make it. I enjoy messing around with fusion 360 at home and would like to learn more.
No, but I thought I'd add that. They do have quite a extensive CAD library which Ive used and has helped and is very useful. Great for a family company and we like those :D

Thanks for showing the tool path creation steps! That is extremely helpful. Would appreciate more examples when possible.
The clock was a nice touch!
Hey John... inside full demo... love the clock, the dog and your attitude. ;) Thank you so much!

Love the 440, probably won't be able to have it as my first machine due to cost, but definitely my dream machine for knife making.
This is some asmr level therapeutic stuff.
Watching the arc of the shavings when it changes angles belongs on /r/oddlysatisfying
yes this is exactly what i'm looking for!

I did end up gettin Fusion 360 but am reading the tip and trick and the essential guide to fusion. Now to mak a bigger bed on my cnc layout.

My favorite widget. As far as I can remember.
Love your videos!
It's shocking to see that I am still studying on outdated machines and components.
Your dog can really walk fast. You should change his name to Whoosh. He doesn't even need go faster stripes.
this is really cool, could you then follow that with doing the sides?
Would timelapse work better if you triggered your shutter when the part passes the same spot each time?
Hey John how would you go about milling the sides of the car body? Rotate on a 4th axis or in a vise?
Hi John, as always - great video. Always learn something in your videos. Your shop and tool show tours are awesome too. The canned TH-cam music could go in the trash - just my opinion 🤗
Great result! Is this the same way plastic or molds for e.g. this 911 are made?
I love this Video, Great work and thanks for the 360 tips, awesome :-)

If you were doing this in an 1100, what would be your cut recipes?
I have been posting my designs to the Autodesk Gallery as well as grabcad. gallery.autodesk.com The gallery seems to have more parametric models.
There's 3DeXchange too.
Good stuff!
very cool
I kinda want a 440 now. Is tormach sending you christmas cards yet? ;)
Is it hard on the spindle to be running 10k rpm for so many of the tools you use?
Regarding that I have an additional question:
Why is climb milling used for the hogging cuts when surface quality isn´t necessary? The tool edge runs into the material full depth, while running into an angled surface would be much easier for the machine and reduce chatter.

+NYC CNC oh that explains why you were all teared up
whats the max feed rate on that machine?
Hey John, check also www.traceparts.com for CAD models of industrial components from the OEM, very usefull
You know that Mc-MasterCarr is family owned.
No, but I thought I'd add that. They do have quite a extensive CAD library which Ive used and has helped and is very useful. Great for a family company and we like those :D
hello are you still active. Please contact me. Super. I'm from Poland
