The example below demonstrates the procedure for machining a curved surface component, in this case a wing section. Roughing Roughing This is the first stage of machining where the object is to quickly remove the bulk of the waste material, normally 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. CNC machining, CNC machinings 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.

with the aid of a ripper cutter (see cutters below), this gives the coarse stepped feature seen in the workpiece above.

Investment casting, also called lost-wax casting, is one of the oldest known metal-forming techniques. From 5,000 years ago, when beeswax formed the pattern, to today¡¯s high-technology waxes, refractory materials and specialist alloys, the castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. The process is generally used for small castings, but has produced complete aircraft door frames, steel castings of up to 300 kg and aluminium castings of up to 30 kg. It is generally more expensive than die casting or sand casting, but can produce complicated shapes that require little rework or machining. Investment casting offers high production rates, particularly for small or highly complex components, and extremely good surface finish (CT4-CT6 class accuracy and Ra1.6-6.3 surface roughness) with very little machining. The drawbacks include the specialized equipment, costly refractories and binders, many operations to make a mould, and occasional minute defects. Investment casting is used in the aerospace and power generation industries to produce single-crystal turbine blades, which have more creep resistance than equiaxed castings. It is also widely used by Sturm, Ruger among other firearms manufacturers to fabricate firearm receivers, triggers, hammers, and other precision parts at low cost. Other industries that use standard investment-cast parts include military, medical, commercial and automotive. From:http://www.china-die-casting.com/What_is_investment_casting.htm | ||
