Engineering activities involved in the creation and operation of the technical and economic processes that convert raw materials, energy, and purchased items into components for sale to other manufacturers or into end products for sale to the customer.
Defined in this way, manufacturing engineering includes product design and manufacturing system design as well as operation of the factory.
More specifically manufacturing engineering involves the analysis and modification of product designs so as to assure manufacturability; the design, selection, specification and optimization of the required equipment, tooling, processes and operations and the determination of other technical matters required to make a given product according to the desired volume, timetable, cost, quality level and other specifications.
Manufacturing process is science and technology by which a material is converted into a useful shape, with a structure and properties. In a simple technical definition of a material processing might be “all that is done to convert stuff into things”.
Manufacturing is an economic term for making good and services available to satisfy human needs. Manufacturing implies creating value by applying useful mental or physical labour.
Modern manufacturing Environment:
In a modern manufacturing environment, an organizations strategy for highly automated systems and the role for workers in these systems are generally based on one of two distinct philosophical approaches.
One approach views workers within the planet as the greatest source of error. This approach uses computer integrated manufacturing technology to reduce the workers influence on the manufacturing process.
The second approach uses computer integrated manufacturing technology to help the workers make the best product possible. It implies that workers use the technology to control variance, detect and correct error, and adapt to a changing marketplace.
A high technology development in computing and electronics, designed to enhance manufacturing capabilities. Advanced manufacturing technology is used in all areas of manufacturing includes design control, fabrication and assembly.
This family of technologies included Robotics, Computer Aided Design (CAD), Computer Aided Engineering (CAE), MRP II, Automated material handling systems, Electronic Data Interchange (EDI), Computer Integrated Manufacturing (CIM), Flexible Manufacturing Systems (FMS), and Group Technology (GT).
The best approach utilizes the attributes of employees in the factory to produce products in response to customer demand.
This viewpoint enables the employees to exert some control over the system, rather than simply serving it. The employees can then use the system as a tool to achieve production goals.
As technology and automation have advanced, it has become necessary for manufacturing engineers to gain a much broader perspective.
They must be able to function in an integrated activity involving product design, product manufacture, and product use. They also have to consider how the product will be destroyed as well as the efficient recovery of the materials used in its manufacture.
