Mill - First big project (In a long while.)

My friend Wolf came over last night... he wants to build a CNC machine from scratch. He wants to be able to cut foam with a hot wire... all under CNC control. He drew up the first couple of parts... one of which is a plate about 10x11 (254x279mm) inches made from 1/4 inch (6mm) aluminum.

The part as laid out in Aspire Software

When we laid it all out, we took into consideration the mill's maximum 11.5 inch movement in then Y-Axis... but we didn't account for the overall size of the sheet. So when we tried to move to the area for the outside cut, it would hit the mill. We had to make all the drill holes, then the inside cut.

For the outside, we had to cut the bottom, move the head forward, then cut the top. We learned to be more careful in laying out the parts... but we managed to get it all done in one evening.

Here it is on the milling machine... I have the inner-hole cutting file shown on the control computer. It worked flawlessly and finished the part nicely.

Wolf and the finished part.

We have several more to make... so we are feeling pretty good about the project so far!
