Time-Lapse CNC Milling Part 2

[vrogy]

Is that one of the new Starcraft's Protoss ship designs?

[cubixthe]

Can You tell me how do You aling it every time it's flipped ??

[KrystianMajewski]

We milled a grove into the ground where the block fits in perfectly.

[cubixthe]

Yeah, I see it now... But what if You would have a piece, that has been cut in 2D on a waterjet (or laser) and then YOu have to mill something precisely on it? How would You position it on the table ?

[KrystianMajewski]

If there are no perpendicular surfaces on the piece - good luck.

One thing that also works sometimes: drill two holes into the piece and screw the piece through that holes into the baseplate. You can use the holes in the baseplate as reference coordinates for the mill.

But then again - if the piece is already cut and it has a weird shape, you can't really mesure where the holes are.

[cubixthe]

But if there are holes in the model and they've been cut on the waterjet (so theoretically they can work as reference), how would You position the object then? If You want to do that a couple of times (and even made a "negative" piece out of wood on the machine - but it has to come off the table sometime...)

[KrystianMajewski]

Oh yeah, haven't thought about using the waterjet for the holes. Well then it's simple. You just screw the model through the holes to the baseplate and set the 0 Point on the top of one of the screws. You can then take the model off, rotate it 180°, screw it back in again from the other side and do the other side.

Actually, we wanted to do that initially. You can see the holes we drilled at the very beginning on either sides of the cube.

[cubixthe]

I'm getting it right now :) The thing is, when I place the part with the holes on the table how do I let the machine know where the hole is?(where to start..) can I mount a tool the size of the hole for example, move it down close to the table so that it goes in the hole, screw the thing down then and tell the machine to start from that spot ?

[KrystianMajewski]

Yeah. Or you can calibrate the 0-Point before you screw in the part. Or maybe you can put a round piece of wood into the hole which is longer than the thickness of the piece and calibrate the 0-Point at the top of that piece of wood.

It really depends on what exactly you want to mill and how your milling machine works.

[cubixthe]

I'm playing with SolidCam right now.. by the 0 point do You mean the 0 point of the coordinates (XYZ) ? By the way are You Polish by any chance ? I'm from Poland ;)

[KrystianMajewski]

Yes, I mean the 0 point of the coordinate system. But also the 0 point of the coordinate system of the machine.

You should really ask the operator of the machine instead of random people on the internet.

no need to replace &feauture, just add &fmt=18 to the URL

[GoMunkNation]

This video is alot clearer if you add &fmt=18 to the end, replacing &feature

[KrystianMajewski]

Wow! Very cool trick. Thanks!

[rccamato]

Nice job! What foam did you use?

[KrystianMajewski]

Honestly, I don't know. The lightest one. It was supposed to be a pre-model, but my colleague decided to make the final model from it by coating it with filler and polishing it to a smooth surface. But it created a lot of problems later on... long story

[crchrdsn]

What the hell is that thing supposed to be? Fun watching the machine do it's work.. seems like there would be an algorithm though designed to cut foam specifically instead of making 10 billion passes on it like it is a piece of steel.

[KrystianMajewski]

It is a part of a model for a futuristic vehicle. The finished thing isn't online yet.

All the passes are necessary to create a smooth surface. In this regard, foam is no different from steel.

[aleksanderaa]

Nice! U can use blender, MOI, Picasoft Mayka,

Winpc-nc and is cheaper.

[junjihyun09]

lol! the best program is surfcam

[Teflonmonkeyjumps]

neet

[vasantb]

what is it? and this machine can be more faster?

[deckelmaho]

Mastercam the best f**k the rest.....

[necrofeeder]

what kind of software did you use to program? autoCAD?

[KrystianMajewski]

Solidworks to do the Model and MasterCam to program the Machine.

[myhandle007]

after 8 hrs of tooling and u drop it 2 remove the waste.

I'd say 9 words. YOUR FIRED, GET THE FUCK OUT OF MY SHOP.

Though u run things how u like i guess.

[KrystianMajewski]

I didn't drop it, the material broke because it was too weak to support its weight. They were supposed to be cut anyway.

I'm not working in a shop, I'm a student and the project you see is a student experiment. No reason to be rude anyway.

[vacuumtuube]

That was pretty cool. What brand of mill did you use?

[Baphomae]

some of the noises sounded like someone was taking a dump XD

good vid though =p

[Nudelsalatbomber]

ein blinker im großformat?

[KrystianMajewski]

A day... about 8 hours

[MUSKETT30]

wow, how long did that take.
