Carved a Colt 1911

I did this plaque for the local shooting club. It is a 3D model of the famous 1911 Colt. Took a couple of hours to carve.

Very nicely done! Details on the tools used, and how you programmed it?

Hi,
yeah, those wooden carved guns are safe too...not an inconsiderable advantage!

Nice work. Post some info on the process used.

The wood I used was an old tray of some sort, I guess that is is teak
I found a 3D model on Thingiverse for the 1911 Colt. Imported that into Vcarve Desktop. Set the cutting depth to ca 9.5 mm.
Created one roughing with 6mm end mill, then did a second roughing with a 1,5 mm end mill.
The finish touch was done with a 0.1 mm 20 degree carving mill.
I have attached the Vcarve-file.

That must have been a huge file, and taken a long time to do! Does V-Carve have the ability to do Rest machining, which is identifying what was reached by a bigger tool and machining only that area?

Yes, in Vcarve you set up the 3D Roughing Toolpath, then the final Toolpath.
The manual for it is here: https://docs.vectric.com/docs/V9.0/VCarvePro/ENU/Help/Toolpaths/3D%20Toolpaths.html
The roughing job took nearly 40 minutes, the second roughing about the same time, the final job took over 4 hours to do.

I took a look at the manual and it doesn’t appear V-Carve does Rest machining. The roughing process removes all the material from where you tell it the surface of the material is, leaving some for finishing. Then your first finish pass cuts to the final part size with that size tool. A second smaller finish tool cuts the entire surface again, or maybe just an area you define.  

That isn’t rest machining.  Consider if your part had a round deep hole that the rougher would not fit into. If your second tool fits it will likely break because in trying to reach the bottom of the hole it will plunge all the way in. You’d have to tell the program to rough only that hole using the smaller tool before finishing with the smaller tool. Rest machining essentially figures out the surface left by the rougher and then calculates where more roughing is needed with the smaller tool.

I use CamBam and was hoping maybe another inexpensive program had rest machining.
