Near-net-shape is an industrial manufacturing technique. As the name implies, the initial production of the item is very close to the final, or net, shape. This reduces the need for surface finishing. By minimizing the use of finishing methods like machining or grinding, near-net-shape production eliminates more than two-thirds of the production costs in some industries.
