Milling a turbine by homemade CNC

[unambitious]

Ya know what? I have the weirdest boner right now.

[D34Df007]

i think this is awesome and all, but i have one question: will it blend?

[waty2hoty]

@D34Df007 actually ya u could definitely blend with it

[HeadShot360IN]

HA! AND THEY SAID YOU NEEDED 5 AXIS TO MAKE AN IMPELLER!

[rmmnet]

Absolutely wonderful. Can you recommend a course of study on this topic for me . I wish to study the technology. Thanks. Please reply to rotimi_morgan@yahoo.co.uk. Thank you.Regards. RMMorgan

Hey hoss, what did you end up doing with this? :)

[diyengineer]

very nice!!! would have been more impressive with a hard plastic. The fuzzy foam dosen't let the true resolution show!! I use solidworks, mastercam and mach 3, what do you use?

[krap101]

@diyengineer I use cut2d/cut3d with mach 3 and inventor... if it matters :P

[diyengineer]

@krap101 What is cut 2D/3D is that the cam program? Free or how much? Easy to use?

[krap101]

@diyengineer cut2d/3d are cam programs, somewhat expensive (200 each or 350 for both or so), and made by vectric, but much cheaper than something like mastercam. I haven't tried out anything else, so I don't have any comparison, but they do work well. My favorite feature is preview, and you can see how your part is going to be cut out. You can download a trial (for both), and there are some demo parts you can do. How I'd explain it is that 2d is extrusions and 3d is curves

[stefke72yamaha]

What software did you use to generate g-code?

[CNCx1]

I used deskprot.

[owyheecnc]

Please explain what or who generated the g-code for this object. Thanks.

[Aev308]

with mach3 can you import files from autocad? I know how to draw 3d parts in multiple cam programs, but I'm much better with autocad, and can't afford mastercam.

[CNCx1]

Sorry. I don't Know how to import files from autocad...

[Aev308]

ok, thanks. I just downloaded demo version and it worked.

[jackcarrozzo]

mach3 is a CNC controller - it takes G code. CAD programs draw the parts (like autocad, solidworks), CAM programs take that shape and draw tool paths in G code (like mastercam)

[krap101]

@Aev308 I think mach 3 imports text files with g-code in them. I use inventor with pdf's, dxf's, or stl's

[Migueldeservantes]

@Aev308 Yes Truly sucks that mastercam is not user friendly like auto cad! I agree with you totally!

[rikirikado]

What kind of lathe is that?

Are you controlling the lathe thru Mach?

[CNCx1]

It's not lathe. 4axis milling machine.

controlling it thru Mach

[MySchizoBuddy]

@CNCx1 how much is a 4-axis milling machine?

[pheenix42]

Nice job! How effective was that turbine once you got the final part made? =)

[diegosua2005]

muy buena la maquina. me podria compartir vuestro soft. gracias.

[rtwas]

What kind of gearbox is that you're using for your 4th axis? Where does one *get* a gearbox like that?

Thanks.

[CNCx1]

This gearbox is called "ball reducer". It's non-backlash gearbox. i got it at second-hand mechanical parts shop.

[evildrome]

What software drives the mill?

[CNCx1]

It's Mach3.

[evildrome]

Mach Turn? I didn't know you could have separate control of the main spindle with Mach 3.

[evildrome]

Ignore me. I see that its a mill with a 4th axis.

[WarewolfFingerboards]

this is SOO FREAKING COOL!

[Ibringthetruth1]

lost wax cast method faster.

[play3393]

hahahaha no it's not

[masterfunkzee]

nice

[Canaviri2021]

Programming Used to control the machine? mach3?

[BigCockvanHugenDong]

i do not envy whoever has to clean that up

[AssassinXCV]

...shop vac

[dddproject]

how in the world did you build a homemade cnc? message me or something, thats great.

[ydna2]

There are actually quite a few ways to do it, some companies make servo-encoder kits that can be retrofitted onto virtually any manual machine (space permitting). After that it's just software to control the axes.

[Titanis2000]

Hey could you send me the G-code for that I would love to try that with aluminum in my 4 axis CNC . thank you

[mitkane]

Was the foam used to make a casting mold?

[CNCx1]

Not yet, I want do it.

[smeahzidente]

BRAVO! good job man!

[buttdagger]

This is way bad ass.

[thegrimreaper63]

pretty cool! but that looks like a compressor wheel and not a turbine....?

[GutterClown]

you seriously do know they're the same thing, right?

[Seanunism]

They are not the same thing.

[GutterClown]

Sure about that?

[equateuser]

Wow great vid. Any chance you'll be posting DIY-Instructions or list of parts and software used? If so, that would be greatly appreciated!

[78ronny78]

I LOVE THIS GAME

[sparkysmini]

yea impellers r alot of work, i made a few before, good job

[aznricejp]

A vacuum would of been a good idea.

[bigtonyicu]

Verry nice work

where did you get the model for the impellor?

I've had such a hard time maping that compound curve. any tips you can give would be greatly appreciated

[CNCx1]

I drew this model with 3D CAD.

[CNCx1]

I made this model by 3D CAD.

I don't have enough knowledge of compound curve...
