Creating the Part
Accessing the CyberCut webpage takes you to a java applet called WebCAD2000 where you design the final 2D or 3D part that will be produced.
In order to guide the user in designing parts that are readily manufacturable on a milling machine, CyberCut uses a feature based, constrained destructive solid geometry (CDSG)6 design environment. This means that instead of building up a part incrementally from "nothingness" (constructive solid geometry, or CSG), the user starts out with a prismatic stock, and remove primitives or "chunks" of material. Instead of allowing arbitrary removal, the user is only able to remove certain shapes of material, referred to as "features." These features take the form of pockets, blind holes, through holes, and face-off operations. In addition, the user can only place features on one of the stock’s original six faces. This design methodology is used to make the problem of process planning a solvable one. The rational for imposing destructive "features" upon the designer is this: Each of these features can readily be mapped to a standard CNC milling process. It is easy to see that these three restrictions -- six access faces, CDSG, and feature based design -- limit the set of parts that can be designed. However, the key advantage of this design environment is that the design-to-manufacture process is more deterministic than conventional methods relying on unconstrained design, and looser links between design, planning, and fabrication
1. Start by choosing the size and type of material. Price is listed.
2. Add features to either of the six sides from those listed. Using the toolbar which gives cutting options. WebCAD Tutorial
3. Save file and send off the CyberCut staff.
4. 4-30 days the part will be finished and shipped off to you.
