Gallery of projects completed with MeshCAM

Made these the other day. Some parts for a new router I'm designing/ prototyping.
I cheated a bit though. The drilling and counterbores were not done with MeshCAM. :o

Order of operations:
1) Drill
2) Rough
3) Counterbore
4) Finish

This was done to eliminate tearout at the counterbore edges. These are only 2.5" long, and there's not much material left at the top edges of the counterbores.

Roughing and finishing were done with a 1/8" ballnose ($5 Ebay), finish pass .005 stepover at 175ipm.

These are straight off the router, and are smooth as glass.

If you're wondering, the material is 35 layers of veneer glued in a vacuum bag with epoxy. Maple and Makore, alternating every 5 layers.

Those look great- what are they? Did you laminate the material all at one time or did you have to do it several batches?

I'm drooling at the idea of a machine that can run at 175ipm.

All glued up at one time with laminating epoxy, which takes several hours to set.

They'll be bolted and bonded to some baltic birch plywood, and I'll be placing a custom threaded insert into the edge between the two. It's basically reinforcement. You metal guys would call it a boss, I guess. ;)

A V groove bearing get's mounted to the insert.

175ipm is nothing. The target for the new machine is 500-600ipm, with 1G acceleration. I'll be very happy with .5G, though. :)

At work, we cut cabinet parts at 950ipm. :lol:

Almost forgot the pic.
