The example below demonstrates the procedure for machining a curved surface component, in this case a wing section.
Roughing
This is the first stage of machining where the object is to quickly remove the bulk of the waste material, normally with the aid of a ripper cutter (see cutters below), this gives the coarse stepped feature seen in the workpiece above.

Semi Roughing
This stage of machining generally uses a smaller cutter than roughing, typically an end mill, although the aim is still to remove the bulk of the waste material.

Semi Finishing
The next stage, using a relatively large ball nosed cutter, is to start to form the final profile of the workpiece, removing the steps generated in the two above procedures.

Finishing
The final stage, and the longest process of all, is the final cut to the desired size. A small ball nosed cutter traversing across the surface produces the finished shape.

Although this is the final machining stage there is still much work to do in the form of hand polishing and finishing before the article is complete.
