5D CNC Milling
 
All the examples we have looked at so far have been created using 2D milling tech- niques. 2D techniques cover a broad range of applications using differing cut depths, feed rates, and cut-depth-per-pass values, but don’t allow you to alter the cut depth during a pass. Because cut-depth data has to be saved with the model, you need a 3D model to create complex cuts. A 3D model includes data for every
 
point on the model, whether or not it is actually part of the workpiece. Although a 3D model is used for this type of work, it is still referred to as 2.5D rather than 3D milling. This is because a 3-axis machine can only engage with the upper surface and exposed sides of a workpiece, but not with its underside or any other hidden areas. In order to access the entire surface, the workpiece itself has to be rotated in two dimensions. In other words, to produce truly three-dimensional components, you need a 5-axis milling machine. The complexity of the machine and the required CAM process make true 3D milling an unrealistic goal for begin- ners.
