I recently started to play with CAM programs were simpler than the CATIA and which are more oriented to the “artistic” rather than machining “industrial” machining. I’ve been testing several demos, including ArtCAM, Aspire vectric, PhotoCarver, etc … And the truth is I were a little complicated. But I was advised the Vectric Aspire, and found on its website a series of tutorial videos (in English, but understood quite well) very good start at least understand how it works. Once I review all of the tutorials, I started to have some “freedom” with the basics and I ventured to work my first piece on engraving.
This 3D modeling program can convert 2D to 3D Photo (well, actually you have to do, but it helps a lot and plant textures fine, when I know I’ll upload a new post) and what I will describe here, machined 2D based vectors. How does this work? It’s very simple. If you have a vectorized image, ie drawn in autocad, freehand, etc … the aspire recognizes and is able to machine doing a engraving after you tell him.
You also have the option to convert a 2D image (jpg) image on vectors, which also greatly facilitates things:
I needed to do the engraving of a pirate skull, so I found a picture online that I found suitable
I will not go on to describe in its entirety here how the program works, but if someone has a specific question, please contact me, I will be happy to resolve it.
Vectric Aspire has the option to convert to vectors, so I transform the image into a vector, as follows:
Once the image is vectorized, it is as simple as giving orders machining and select the vectors. There are many options, but I chose milling cutter recorded in V, leaving machining of this type:
Of course you have to set the cutting conditions, and then the code is exported. For users of LinuxCNC, I advance in Vectric Aspire, you have to save the program format: EMC2 Arcs (mm) (* ngc.)
I personally know a little code, I add the number of tool, or modify the coordinates of input or output, but that’s going according to taste. The code usually goes pretty smooth and virtually no need to touch anything.
Well, once generated the code, plugged it into the router, do part zero, and the party starts:
The quality of machining depends on the milling that has (I was using a Bricodépôt of the pack of 12 strawberries I went for 7 €) and wood (plank I found on the street)
Still, the result is quite good.
As the “request” I had to do included text, I continued researching, and the truth is that it is extremely easy to make a text engraving, for Vectric Aspire directly transforms the text into vector machine it can then no problem. I put “El Moral Los Piratas” as you will see:
Now I have to do is varnished wood, or bitumen, to grow old the wood, then sand the surface so that the letters remain more prominent, but that’s another story.
What I wanted to show is how extremely easy it is to do this type of work.
As always, I encourage you to build a machine like this, if you do not like these “crafts” or if you only need a woodcut, please contact me. I’ll be happy to make a personal request, including the CAM programming
