Tried out 2-sided machining and learned a lot!

Awesome - Good Job.
I'm full of questions.
How long did it take to cut both sides of the wave project?
What cutter did you use?
and what was the Depth of cut per pass?
It is what it is!
Have a great day.

Looks good What method did you use in the software and on the Cnc router to index your program and material so that when you flip it over you still have a known orgin or index point.
It is sometimes a pain but results like yours make it worth the effort! Nice job

(Sorry for the slow reply - I did't realize I hadn't selected the option to get e-mail notifications)

First off thanks it was a really fun project! Now to answer your questions:

1) Machining time: Each side took about 20 minutes for the roughing cut then about 40 minutes for the finishing pass. So it took about 2 hours of total machine time for the entire project.
2) Cutters used: I used a standard 1/4" endmill for the roughing, then a 1/4" Tapered Ball-nose from Precise Bits for the finishing.
3) Pass cut depths: I used 1/8" passes and then just left a 0.012" machining allowance for the finishing pass.
4) Indexing for flipping the part over: On the top side I cut holes beside the part that would fit some dowels I had. Then when modeling the bottom side I just inverted the hole locations. Then when I ran the bottom side, I clamped a piece of MDF down, set the zero point and the routed out the same holes. In the holes I inserted dowels. Next I put the material back on face down aligning the dowels into the holes (this made sure I had the x-y plane perfectly aligned) and then finished the bottom side. I was quite worried that the tabs would break during machining on the bottom side since they were only 1/8" thick -- but since there were 8 of them they ended up being very sturdy. I got this method from a Vectric tutorial on a Two Sided Leaf Bowl project.
