Joining and Assembly Processes Casting, Molding and related Surface Processing Operations Processes Material Removal Processes Automation, Production Systems and Modern Manufacturing Techniques What is Manufacturing? What is Manufacturing? The word manufacture is derived from two words – Manus (meaning hand) and Factus (meaning make) Technologically - it is the application of physical and chemical processes to alter the geometry, properties and/or appearance of a given starting material to make parts or products Economically – it is the transformation of materials into items of greater value by means of one or more processing and/or assembly operations Why Manufacturing? Why Manufacturing? Transformation of value Job opportunities Boosting the economy Manufacturing Processes The kind of manufacturing done depends on the kind of product you are making Classification of Manufacturing Processes Casting, Molding and Related Processes Forming Material Removal Processes Types of Machining Operations Turning – a cutting tool with a single cutting edge is used to remove material from a rotating workpiece Drilling – used to create a round hole Milling – a rotating tool with multiple cutting edges is moved slowly relative to the material to generate a plane or straight surface Joining and Assembly Processes Surface Processing Operations Cleaning – mechanical, chemical Surface treatment Coating and deposition – e.g. for corrosion protection, attractive appearance, wear resistance, etc. Class Activity For each of the following, try to answer the following questions What is it? What is its purpose? How is the process like? Electroplating Electroforming Electroless plating Hot dipping Modern Manufacturing Techniques CNC Machining Additive Manufacturing and Prototyping Automation and Production Systems The assembly line Robotics Logistics and other support systems Thank You? Any Questions?
