That is impressive. The finished piece looks great, I have to say the Carve King has earned it's crown!

Wow Derek, that finished aluminum piece looks great. Very impressive. I'm getting excited...just a bit. So what software did you use to put the code together for that?

Awesome piece of work!! Wanted to ask what cutting bit was used?

I did some wood and it chipped in a couple of places.
I thought I was going too fast at 39 inches per minute.
I thought the z axis is not going to be able to keep up and lift fast enough.
But Derek seems to be rippin along at the same speed and the finished aluminum part looks fine.
heh

The chipping can be for a couple different reasons, and sometimes seemingly no reason at all. One technique people use sometimes is to put painters tape over the piece. |

I am glad to see that the machine can do this.
Just have to keep everything in the sweet spot.
It looks great.

Cross grain cutting will always produce more tear out (chipping). Sometimes it's better to do climb cutting opposed to conventional and vice versa. If it's tearing out try the opposite. Try to orientate your material so the majority of the cutting is with the grain. After all this, no matter what you do, up cut bits will always cause a little tear out on the top ESPECIALLY in stuff like pine as the fibres are soft and loosely packed so they tend to pull out along with the shearing action of the cut. This is where the painters tape comes into play. You could also use a down cut or straight flute to minimize the issue of top. |

You are 100% right the chip is where the grain is across and on an up cut. Also the design of my v carve tool is not the best. I think it should have more relief and almost be like a single flute at the tip. The one I used looks like it is plowing the tip through, not cutting.
Anyway I now return this thread back to the point - Awesome 3D aluminum part Derek!
