3D Cutting and CNC Routers 3D cutting, machining and sculpting can be used in many different types of projects. It is one of the most impressive capabilities a ShopBot CNC tool will bring to your shop. All ShopBots have full 3D capability, and the high-speed capabilities of PRS ShopBots make them excellent for efficient 3D work. There is a lot of confusion surrounding 3D and how to best make it work for you and your type of application. This section is intended to provide you with an introduction to 3D and to clarify how you might to incorporate 3D features into your work. Understand at the outset that there are a lot of different ways to do 3D and there will probably be at least one that is right for you.

From Jim Lohmann What 3D Is Not ShopBot CNC tools are all fully 3D capable, as are most CNC routers today [this capability is technically described as 3-axis interpolation, which means that moves are made smoothly in 3D space using diagonals and curves]. There was a time when the Z axis of some CNCs moved only when X and Y were not moving, or only had a single up and down position. These earlier CNCs were thus not capable of 3D carving and were referred to as 2 or 2.5D tools. Now, rather than specifying the capability of a CNC tool, the terms 2, 2.5 and 3D are more descriptive of the nature of the design side of a project; either what is done with the design software, or what the design software is capable of doing. Here's a little sample: Clarifying Designing in 2D or 2.5D If all we have is a flat outline of something we want to cut out, that would be considered 2D. If we then added straight up and down movements of the cutter into and out of the material, we might now consider the project as 2.5D.

This 2.5D work starts off as a 2D design in principle, but during the process of creating the tool path or cutting file you will typically assign a depth or multiple depths for the tool's motion to cut features like grooves or flat pockets. When the software generates the part file, the instructions will first move the CNC tool to the assigned cutting depth (in the Z axis), then move the cutter through the XY tool path at that depth, and then return to the starting height with a straight pull-up. Thus, when the file is finished, the cutting tool has moved in three dimensions (X, Y and Z), but all the X and Y axis motion is in a single plane and the X and Y axes stop when the Z axis plunges or pulls up. So, for the case of this example, the drawing and design process are fundamentally 2D. Standard cabinetmaking would be a good example of such a 2D or 2.5D project.

You can sort of fudge 3D with 2D techniques by working with a build up of layers. A project like a contour map with distinct Z-axis layers is one example; another is Ed Lang's layered fighter.

Designing for CNC using 2.5D CAD/CAM software is fairly straightforward because you do not have to worry about visualizing your part in three dimensions or describing complex tool motions. And, 2.5D CAD/CAM works well for any project where you are cutting parts out of sheet material, or where you are pocketing areas (e.g. Around letters in a sign). All such cutting can be done in one or more different cutting planes after plunging to a cutting depth. VCarve Pro ShopBot Edition, which is provided with every ShopBot CNC system, is an excellent basic program for 2.5D CNC design (CAD) and for generating toolpaths from the design (CAM). In addition, VCarve Pro ShopBot Edition can important 2D files from other design programs for editing, adding plunge movements and outputting toolpaths. Tool paths in 2.5D V-Carving Might be All You Need It is also common to consider V-carving as a 2.5D design process.

This technique uses CNC motion with a v-shaped cutter to give a classic chiseled look (also called chip carving) to lettering or other shapes that would traditionally have been carved by hand. The 2.5D description is appropriate because the design that you work with is still 2D in nature, even though the actual CNC movements that create the chiseling effect involve full 3-D, simultaneous XYZ motion of the cutter. V-carving is a great way to add an impressive look to your lettering or sign work and decorative wood carvings.
