Near-net shape quality gears. The majority of forged gears produced today are near-net shape configurations. Gear teeth are forged with an envelope of material (stock allowance) around the tooth profile. This envelope is subsequently removed by the forging house or the customer purchasing the forged gears. The manufacturing process begins with.

      The Additive Manufacturing technology is an innovative solution for the manufacturing of Near Net Shape (NNS) or Net Shape (NS) . Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a g is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working).For the latter two, the metal is .

This book covers the mechanism, salient features, and important aspects of various subtractive, additive, forming and hybrid techniques to manufacture near net-shaped products. The latest research in this area as well as possible future research are also highlighted.

Near net shape is an industrial manufacturing technique. The name implies that the initial production of the item is very close to the final (net) shape, reducing the need for surface ng traditional finishing such as machining or grinding eliminates more than two-thirds of the production costs in some industries.

This book sheds light on near net shape manufacturing processes. It covers mechanism, salient features, and important aspects of various subtractive, additive, and forming techniques to. Powder injection molding is a near net-shape manufacturing technique for complex metal or ceramic components.

The first step in the manufacturing process (Figure 1) is the careful choice of the ingredients of the compound that in general consists of a polymeric binder system and the metal or ceramic powder. Binder system is a mixture of all. Near net shape manufacturing can be applied to a wide variety of media.

It's often used in metal working, particularly with titanium and other expensive alloys. This process can also be used in ceramics making, where spray or gel ceramics can offer a near net alternative to milling or machining.

near-net-shape manufacturing examples in advanced process chains Casting: Selected Examples The main advantage of shaping by casting or powder metallurgy is the realization of near-net-shape production of castings and sintered parts, thereby minimizing cutting processing and drastically short- ening the process chains due to fewer process stages.

Net Shape Manufacturing for RocCera Ceramics. Net shape manufacturing focuses on the manufacture of discrete parts to net or near net dimensions. In the past, a ceramic component has been 2x to 5x more expensive than a comparable steel component.

Traditional ceramic machining requires diamond tooling and longer processing time. Kuang-Hua Chang, in e-Design, Laser Engineered Net Shaping. Laser engineered net shaping (LENS) uses computer-controlled lasers that, in hours, weld air-blown streams of metallic powders into custom parts and manufacturing molds.

The technique produces shapes close enough to the final product to eliminate the need for rough machining. Near-net-shape describes a group of manufacturing processes. These are designed to limit the material application. It is deposited only within an envelope very near to the final volume of the finished item.

This presentation will show methods where the material is applied by fusion welding. High energy processes like Electron Beam and Laser Beam technology are used.

Near-Net Shape Manufacturing These processes produce parts in a manner which does allow use of rules to relate design attributes to manufacturing ones.

Hence rule based systems found much success here. However recent trend is to use the process physics knowledge and simulation to find out the manufacturability.

Introduction • Net-shape and near net-shape, subsequently referred to as just net-shape, manufacturing can be defined as ‘the manufacture of a component or section of a component by consolidating material with minimal loss or wastage’. Near net shape technologies have expanded these concepts, targeting mainly primary shaping process, such as casting or forging.

The desired outcome of manufacturability analysis for near-net-shape (NNS) processes is cost and lead-time reduction through minimization of process steps (in particular cutting and finishing operations) and raw Author: D.

Marini, D. Cunningham, J.R. Corney. This book covers the mechanism, salient features, and important aspects of various subtractive, additive, forming and hybrid techniques to manufacture near net-shaped products.

The latest research in this area as well as possible future research a. Near-net-shape casting (NSC) is a family of techniques where the initial part production provides a quality surface finish and is close to the final (net) shape. Reducing the need for machining and grinding can eliminate more than two-thirds of the production cost in some industries.Net and near net shape forging represents some relatively recent developments of the conventional impression die forging process.

Net and near net shape forgings are distinguished by geometric features that are thinner and more detailed, varying parting line locations, virtual elimination of draft, closer dimensional tolerances and with many as-forged surfaces.
