Need a cool program to demo to a CNC college class

[danielm]

I've agreed to show a trades skills print reading class an introduction to CNC mill setup and running a program.  Does anyone have something 'cool' that's easy enough to demo a part out of aluminum?  Say...6 tools or less and something that will be no bigger than a 3" cube? The machine is a 3ax Hass VF2.

 

Thanks for any help!

I teach machine trades in the evening.the class is 3 hrs and usually all of the "cool" things take longer than that.

what timeframe do you have?

[danielm]

The class is three hours. I'm the instructor so I'll be able to plan ahead enough to make it happen.  Thanks for asking.

Make a logo or a simple shape. In High School years ago we had to make a Star by hand. We had to lay it out, cut it out and finish it all by hand. We made up all the names of the school board members out of 1"x 2" Alum Bar. All were hand made and polished by the students.

 

Maybe make a Pencil Holder or a Card Holder with the name of School on it.

What I was hoping for was some kind of gadget.  An example is: start with a 2" cube. Vise on it to full depth (std hard jaws).  Use a .25x1.25loc carb em. The program pockets out 6 different shapes all with a unique shaped island (round, square, star, oval...) on top of a round boss. The boss is to a depth of about Z-.3 from the face. The program stops 6 times to flip the part to the next face of the cube. when its all done there is a milled do-hickey that is trapped inside the excess of the cube and it just knocks around inside like some kind of brain teaser puzzle.

 

Maybe I'll just do that.....but I was thinking that there was still cooler stuff that I couldfind here.

They have some project books on the in house store but your idea sound pretty kewl.

Good Luck

I put a Sphere in a Cube on the FTP years ago you could scale down to that size if you wanted to use it.

A turners cube would be pretty cool. At that size you could do it in about 20 minutes if you learn the program and use probing or part stops.

 

Check youtube for turner's cube. You can also find a crap load of solid free on grabcad.

I did one for an open house when I was in school that was just a wavy surface with the school name engraved on it.

AR-15 lower?

AR-15 lower?

Now that will get the students attention and likely some very unwanted attention also!

^{AR-15 lower?}

So you can give them away as party favors?

I think you can in Texas

I remember I went to a dealers bbq lunch and we got to make little 3d F-16 jets out of 3.0 x 2.0 x .75 6061 aluminum. The program ran for about 18mins

So, what'd you decide to go with?

G00 Z-300 is always kind of cool to watch. 

 

On a more serious note, those F16's look pretty sweet.

Maybe it's a local thing but since trade school I've always heard "watch out for rapid Z China".
