Machining A Key Fob Mold on a Tormach 770 | WW192

[@MrToolean]

Flash is because you have too much sealing surface area. Make the sealing surface around each cavity raised by 5 thou, the rest of the tool doesn’t need to touch the mating half. For example, I would have made a quarter inch raised surface around each cavity.

[@MojoMfg]

Seeing you machine all these different kinds of materials just keeps building my confidence. I'm going to try out titanium on my 770 here soon.

[@TomOConnor-BlobOpera]

Using the bridgeport as the power source for the casting is inspired!

[@hamiltonpianos]

As someone who's just looking at getting a CNC router, this looks incredibly complicated! Very nice to see that everyone makes mistakes, and even better to see how you sort out the problems. Great video! :)

[@Ryan_Lundy]

Those high feed mills work great for low rigidity mills. I regularly run a 3 flute 1.5" sandvik high feed mill at 300 ipm in steel on a very low rigidity mill.

[@hawkuu]

@NYC CNC To reduce the flash around part you could use relief channel that need to be machined only at one side of your mold. Clearance/Offset from outside countur should be 0,2 mm. To mill channel use ball end mill.

Hope there's a Tormach in my future... Love this stuff! Thanks!!!

[@DCT_Aaron_Engineering]

They video was totally awesome John, and I thoroughly enjoyed it ;-). Huge thumbs up from me. Cheers, Aaron.

[@TAWPTool]

Yet another fantastic video John! Great work.

[@BlueSwallowAircraft]

Thanks for this video. Very helpful with the type of work I do, making molds and engraving. I will try that small ball mill sometime soon!

[@jasonruch3529]

That was an awesome video! 😍

[@michaelseverns46]

John, definitely stone the 2 mating faces and maybe electro polish both parts to help remove cutter lines in the actual cavity.

[@OwensEngineering]

Great video, really enjoyed this one!

[@VId_Kok]

Wow, that came out amazing!

[@kenwhite451]

Great vid very nice taking time to bring all along, Tradespeople are at short supply to the loss of us all

[@kaushalprajapati1127]

Hey, big fan of your work. I just wanted to request you that when you put up videos with machining recepies please include metric value details also. Because i am from india and i work with metric values ...this is a heartly request.

[@tedjackson5272]

I was waiting for the blue hose to come out!

[@theAustriaball]

Cool project. 1.2311 is overkill, maybe mention that low alloy steels such as 1.1740 are enough to make this mold.

[@katawatenshu]

hudson seems to ship to canada as well

[@xenonram]

You'd think the software would know that that would hit. It literally SHOWS it cutting through that "island" of material. It should ALWAYS be "model aware," as you call it. That blows my mind that the software wasn't developed to take that into consideration automatically.

[@Eggsr2bcrushed]

Andrew Delashaw powermill is conscience of that sort of thing

[@johnalexander2349]

It seems to me like 50% of their time is spent fighting with Fusion. And they're the pros - it's over 90% for an amateur like me. I do barely any 3D modeling, so I have no clue what else is available, but this can't be the best that the software world has to offer.

[@b3nsb3nz]

If you listened to what he said, he told the software ignore the model, just look at these patched surfaces... It was his mistake in this case not the software, 3d toolpaths are normally model aware.

[@natedawg003]

It does normally. He told it to only take into account the patched surface.

[@occamssawzall3486]

You’d think you’d watch the whole thing before posting. He removed the model awareness to force it to machine specific patches surfaces, IE additional surfaces he added in. So it was in fact “model aware” cept he essentially told the toolpath that the entire model was just those 4 patched surfaces.

[@tstanley01]

8:47 LOL...Simulation FTW...

[@smusick1955]

At 11:55 - given IPT is 0.001", why is the cutting feedrate only 10 ipm instead of 20 ipm as it is listed as a 2 flute tool? Do you only define this engraver as a 1 flute tool?

[@mikimexicali]

i like this video

[@bhoiiii]

I want your trust fund. J/K love these vids!

[@turbo2ltr]

So they are solid keychains, not hollow for putting electronics inside?

[@Fischer977]

turbo2ltr think they are going to overmold plastic on the electronics

[@sunnysidecnc8533]

I need that modular endmill.

[@NerdlyCNC]

which insert was used in dijet?

[@danl.4743]

3:12 That steel is transparent!!!

[@GeofDumas]

have you ever had your tormach spindles reground? That's where the majority of my runout came from but I never got it done. place up in concord quoted me 500 bucks IIRC. definitely worth it eventually but I just don't use it enough right now

[@dztrbdgod]

Would using a heat shrink collet for really small bits reduce runout?

[@terrysharp6294]

Do you think venting the mold, like they do in Injection Molding, would help with the flash issue?

[@Daniel-vq9zb]

Terry Sharp No it won't help, you vent a mold to let gases escape and allow the plastic to fill the cavity easier, the problem he is having is flashing around the edge of the mold which is likely from the A and B half of the mold from not being very flat or, miss alignment of what ever locating geometry ( likely dowel pins in this case ) the mold has.

[@terrysharp6294]

True. He could relieve none essential areas of contact as well. That would help

[@Daniel-vq9zb]

Andre Gross actually alot of the time mold bases are milled on the parting line, keep in mind that a small injection molding machine is around 50 ton press, so they force the mold closed, also alot of materials are very forgiving such as abs which flashes in about a .005 gap

[@TheLeeMacDonald]

What was the material you poured in the mold?

[@h2opower]

Your really had an expensive day with all the broken end mills on this one.

[@tomkeating65]

What are the specs of the computer you use for programming all this?

[@jodyolivent8481]

He has a list here. www.nyccnc.com/computer-buy-fusion-360/

[@BRZZ-xw4hd]

Identical including the crash he he ... peace out

[@ShortCourseWorld]

Did tormach ask for this video?

[@MrDaniell1234]

I wont a 770

[@justinmoritz6543]

I still don't know why "Wednesday wodget" is released on Tuesday. This is a Tuesday widget wtf

[@urgamecshk]

Justin Moritz so it's available to everyone on wednesday

[@justinmoritz6543]

Julius Jahn as in the morning of?
