Non traditional machining

Classification of non conventional machining process: Burnishing is an example of a miscellaneous operation.

Non Traditional Machining Processes

Cutting tool machining A "numerical controlled machining cell machinist" monitors a B-1B aircraft part being manufactured. More recent, advanced machining techniques include precision CNC machining, electrical discharge machining EDMelectro-chemical erosion, laser cuttingor water jet cutting to shape metal workpieces.

Non-traditional Machining Processes - PowerPoint PPT Presentation

In many cases, fabricated metal meshes provide better value and performance than woven wire. More recent, advanced machining techniques include electrical discharge machining EDMelectro-chemical Non traditional machining, laser cutting, or water jet cutting to shape metal workpieces.

Schematic representation of various metal cutting operationsTraditional machining sufficed the requirement of the industries over the decades.

A spark is sent from the shortest distance between a single strand of wire, usually brass, and the workpiece where it jumps the gap known as the spark gap at which point material is burned away from the workpiece.

Takes such forms as electrochemical grinding, electrochemical honing and electrochemical turning. A finished product would be a workpiece that meets the specifications set out for that workpiece Non traditional machining engineering drawings or blueprints. In this process, a high velocity water jet is used to machining work piece.

Reaming is one of the sizing operations that removes a small amount of metal from a hole already drilled. Since Wire EDM is mainly used for cutting shapes through assemblies and inserts, it is usually necessary to predrill a hole for the wire to be fed through in order for machining to be completed.

The gas is then passed through an air dryer to remove any residual water vapour. Thus classification of NTM processes is carried out depending on the nature of energy used for material removal.

Generally macroscopic chip formation by shear deformationPage 5 Material removal takes place due to application of cutting forces energy domain can be classified as mechanical Cutting tool is harder than work piece at room temperature as well as under machining conditionsNon Traditional Machining NTM Processes on the other hand are characterised as follows: In turninga cutting tool with a single cutting edge is used to remove material from a rotating workpiece to generate a cylindrical shape.

In current usage, the term "machining" without qualification usually implies the traditional machining processes. More power required for machining. The broad classification is given as follows: Besides the obvious problems related to correct dimensions, there is the problem of achieving the correct finish or surface smoothness on the workpiece.

The process will work on material regardless of hardness. The former ones provide basic shape and size to the material as per designers requirement.

This heat energy use to remove metal by melting and evaporation of metal particles. Gases like CO2, N2 can also be used as carrier gas which may directly be issued from a gas cylinder. VolumeIssues21 NovemberPages The Wire EDM process is utilized only when the required cut goes through the entire workpiece.

To remove any oil vapour or particulate contaminant the same is passed through a series of filters. Complex geometrical shapes can be machined repeatedly and accurately Electrochemical machining is a time saving process when compared with conventional machining During drilling, deep holes can be made or several holes at once.

The sieve is constantly vibrated by an electromagnetic shaker. An electrolytic cell is created in an electrolyte medium, with the tool as the cathode and the workpiece as the anode. Casting, forming, powder metallurgy are such processes to name a few. Laser Beam Machining Process: In the convention machining processes, tool is in direct contact with work piece.

Collectively, speed, feed, and depth of cut are called the cutting conditions. In this machining process an electric spark used as tool for machining. GATE Mechanical Engineering syllabus contains Engineering Mechanics, Mechanics of Materials, Theory of Machines, Vibrations, Machine Design, Fluid Mechanics, Heat-Transfer, Thermodynamics, Engineering Materials, Casting, Forming and Joining Processes, Machining and Machine Tool Operations, Metrology and Inspection, Computer Integrated Manufacturing, Production Planning and.

Makino 5-axis horizontal machining centers provide unprecedented levels of productivity and accuracy in the most complex, full 5-axis machining applications. During the course of machining targets for various experiments it sometimes becomes necessary to adapt fixtures or machines, which are designed for one function, to another function.

When adapting a machine or fixture is not adequate, it may be necessary to acquire a machine specifically designed to. A non-traditional career is any occupation in which women or men comprise less than 25% of the workforce.

Non Traditional Machining Some past engineering industries have witnessed a rapid growth in the development of harder and difficult to machine material such as hastalloy, nitralloy, waspalloy, nimonics, stainless steel and many other high strength temperature resisting alloys.
