Crest part on a Cheap CNC

[paulried]

HomeCNC emailed me the 4 tool paths that cut the crest on his home made machine. I wanted to see how a Cheap-CNC matched up. I think the part looks great! It took much longer on the Cheap-CNC but then again, it only gets around 12 IPM so that was to be expected.

The first two tool paths were roughing passes

28 minutes for the first
22 minutes for the second

The final two paths were finish passes.

Pass #3 with an 1/8" ball nose took 3 hrs 37 minutes
Pass #4 with a 1/16" ball nose tool 18 hrs 26 minutes!

I must agree with HomeCNC in that the 4th pass was not really needed as the detail after pass #3 was almost identical to the forth.

To give you an idea of size, here is another photo with the machine

Wow very nice, but boy that sure took a long time!

Your telling me! I think it took HomeCNC around 8 hrs. The last pass is the killer as the cutter overlap is verrrrrryyyyyyy high. Fun to try, but definitely would not be a money maker for a living!

[HomeCNC]

Yes, I have refined the process and I now know the largest pass for each ball cutter that still looks good. Also I have determined that the size of the part will dictate the use of the 1/16 cutter. My second crest run was larger and I stopped with the 1/8 tool but passed the 1/16 tool over only the artwork in the middle. In the second crest I used a dragon instead of a griffen. The complete time to make the second crest was 10 hours and it was 9" X 14" and a much deeper relief than before. It looks great!

Photo of the new one?!?

Hang on I will take one!

Here is the second go around with my machine.

Now that looks sweet!

Are you using them for something or just playing? They would make great doors for a dart board set in an Irish Pub! Yes it has been a long day.

Cool,

What kind of wood is that?

I am making them as demo cuts. My partner is taking them around to cabinet shops to see if we can drum up work.

The wood is African Ribbin Mahog. My friend works at a nice door shop and got some scrap for me to play with.

Nice work gentlemen.
