Scanned Images

Postby Rob Davis » Wed, Nov 16 2005, 2:32PM

Do any of you have experience in scanning in images of logos or such and then machining them? I have two projects we'd love to add some scanned image \"carving\" to but not sure how to do it. We have ECabinets and MasterCam.

I posted here becasue I am sure the software guys would say it is easy but I mant to machine it and I bet that is another issue.

Thanks!

What type of image is it? Depending on what your trying to do, MasterCam can do something similar, but requires some cleanup on your part. Not sure what level of Mastercam has this option, but it would be under; File>Converters>NextMenu>Rast2Vec. This option allows you to import .bmp, .gif, .jpeg, .pcd, .pcx, .tif formats. You may have to adjust the import settings to your likings. It does have a preview window to help also.

Image Carving

Postby Daniel Carr » Tue, Jan 03 2006, 12:59AM

The VS3D software is designed specifically for 3D carving. Converting an image to vectors, usually involves tracing the image brightness levels to produce lines. VS3D can perform this kind of automatic tracing.

Another technique is to carve a continuous surface using the image brightness as surface height. VS3D can do this, and it includes virtual sculpting tools (hammering, scraping, etc) for manuipuilating relief surfaces.

And yet another technique is to use a V-bit in \"peck\" mode to carve image \"pixels\" as dots of various depths (and thus, widths as well).

Here is a simple tutorial showing the carving of a logo from a digital image:

And here is a more advanced tutorial showing how to carve a continuous surface from a portrait photograph:

PS: VS3D also outputs CAM files compatible with Thermwood routers.

Thanks Dan. My image is not that complex. I am more engraving than carving. But the tutorial is neat.
