3D Cnc Carving S How To Work With3D Cnc Carving S Software Application YouWe have written this article to give you an introduction to 3D CNC and 3D relief Carving using CNC Routers and to show you how to work with 3D features with whatever type of software application you use in your work. Not everyone uses the same methods andor software for 3D Machining but understanding the different choices will help you choose a method thats right for you. Some earlier CNC machines were not capable of 3D carving because either their Z axis moved only when X and Y were not moving or they only had a single up and down position. These were called 2 or 2.5D robotic tools. The 2D or 3D terms now refer to what the design software can do rather than the designing side of the project. Once you add straight up and down movements of the CNC cutter in and out of the material you are using this is called 2.5D. Your project starts off as 2D but can change to 2.5D during the process of your tool path creation. This occurs when you assign a depth for the CNC machines tool motion. The instructions first move the CNC tool to the assigned cutting depth in the Z axis and then moves the cutter through the XY tool path at that depth. The instructions then returns the CNC tool to the starting height with a straight pull up. So in essence, when the file is finished the cutting tool has actually moved in three dimensions.the X, Y and Z, but all the X and Y axis motion is still in a single plane and the X and Y actually stop when the Z axis plunges or pulls up. All of this type of cutting can be done in different cutting planes after dropping to a cutting depth. This is called 2.5D even though the design you are working with is still 2D in nature and the CNC movements that create the chisel effect involve full 3D, which contains the simultanuous motion of the X, Y and Z motion of the cutter. You can definately add a spectacular look to your sign work or woodcarvings with V-Carving. Its very easy to do because the layout process is still in 2D so its easy to create designs and makes carving letters much faster. Below is an example of a Vcarved logo and a fish platter that used V carving, profile cutting and pocketing. A 3 Axis machine has simultaneous cutting motion in the X, Y and Z axes. When cutting in 3D your CNC cutter tip follows paths in 3D curves or angles when carving complex shapes into material. D takes full advantage of your CNC tools capabilities to produce contoured shapes cut to your specifications. You have almost unlimited shapes and contours that you can machine and you can mold them to be uniquely your own designs. If you are going to work in 3D you need to separate the process of designing from the actual tool path generation process. There are separate software programs for each.( MeshCam ) There are only a few programs that provide both capabilities.( MeshCam ART ) 3D designs are used in the world for lots of other purposes than just CNC cutting so there are many approaches for the design process. Its called modeling because you build up your 3D object by inserting and modifying basic 3D shapes rather than drawing with lines. If you havent modeled or created 3D shapes on a 2D computer screen before it will take time to get used to this process.
