Keywords: What is Production Process? Production Process of a workpiece involves the transforming a raw material form its original state to a finished state by changing its shape or the properties of the material in a series of steps. It is generally classified into six groups: The first being Primary shaping Process, which is the production of a solid body from a molten state, gaseous state or amorphous materials like glass; poured into a hollow space of desired shape. Examples include Casting and Powder Metallurgy. Second comes Deforming Processes which makes use of stresses like tension, compression, etc. to deform a material in cold or hot conditions without changing it's mass or metal composition. Some of them are Forging, Rolling, Sheet Metalworking and Extrusion. Third is Machining Processes in which the material is removed by providing suitable relative motion between the workpiece and tool to generate required size and shape of the component. Examples are Drilling, Milling, Turning etc. Fourth is Joining Processes, here two or more pieces of metal parts are joined together to make a final component using heat and/or pressure. Examples include Welding soldering, Brazing, Adhesive Bonding etc. Fifth and the last second group is Surface Finishing Processes, in which only a negligible amount of metal is removed from the workpiece to provide a good finish or a protective coating. Examples are Grinding. Sixth and the last group is Material Properties Modification Process, which are the processes that provide certain specific properties to metal parts so as to make them suitable for particular operations. Examples include Hot and Cold Working.
