Manufacturing Engineering

Manufacturing engineering is a discipline of engineering that looks at the different manufacturing practices and the research and development of systems, processes, machines, tools and equipment. This field deals with machines that turn raw materials to a new product. It also looks at the integration of different facilities and systems for producing quality products by applying the principles of physics.

Manufacturing engineers develop and create physical artifacts, production processes and technology. The manufacturing engineering discipline is integrated with mechanical engineering, industrial engineering, electrical engineering, electronic engineering, computer science, materials management and operations management. Manufacturing engineering emerged in the mid-20th century when industrialized countries introduced advanced statistical methods of quality control and industrial robots on the factory floor.

Modern manufacturing engineering includes all intermediate processes required for the production and integration of a product’s components. Industries use fabrication to descript the following processes; automation and robotics. Automation refers to the application of automation to produce goods in a factory. Robotics is the application of mechatronics and automation to create robots which are used in manufacturing to perform tasks that are dangerous, unpleasant or repetitive.
