1. What is Manufacturing Process ?
The study of manufacturing process deals with several aspects of workshops practices also for imparting the basic working knowledge of the different engineering materials, tools, equipments, basic concepts of electro- mechanical controls of machine tools, production criteria’s, characteristics and uses of various testing instruments and measuring or inspecting devices for checking components or products manufactured in various manufacturing shops in an industrial environment.
It should provide the knowledge of basic workshop processes like bench work and fitting, sheet metal, carpentry, pattern making, mould making, foundry, smithy, forging, metal working and heat treatment, welding, fastening, machine shop, surface finishing and coatings, assembling inspection and quality control. It emphasizes on basic knowledge regarding composition, properties and uses of different raw materials, various production processes, replacement of or improvement over a large number of old processes, new and compact designs, better accuracy in dimensions, quicker methods of production, better surface finishes, more alternatives to the existing materials and tooling systems, automatic and numerical control systems, higher mechanization and greater output.

2. Classification of Manufacturing Process
Different manufacturing process plays an important role to shape the raw material into final product. Manufacturing processes has evolved by the research in the desired quality and durability of the product. The various manufacturing process used in the industry are classified as following.
- Primary Shaping Process: Casting, Forging, Rolling, Bending, Drawing, Squeezing, Extruding, Shearing, Forming, Piercing, Spinning, Crushing.
- Machining Process: Turning, Drilling, Grinding, Threading, Boring, Slotting, Planing, Milling, Hobbing, Sawing, Broaching, Knurling.
- Surface Finishing Process: Blasting, Buffing, Lapping, Honing, Polishing, Electroplating, Tubling, Galvanizing, Anodising.
- Joining Process: Welding, Soldering, Brazing, Riveting, Sintering, Screwing, Bolting.
