Manufacturing technology 1 important 16 Mark question with answer

Manufacturing Technology-I has been come under the syllabus of Third Semester mechanical engineering syllabus. For this ME 2211 subject our website sugest the author G.Shanmuga sundar, he is a mechanical engineering Ph.D completed staff and he is currently with the Anuratha Publications. In this point students and faculty members can download the Manufacturing Technology important Two Marks ans important previously asked questions for ME 2211 MT-I. We hope this will be very much help for the students and faculty members those who are looking for to score high score in manufacturing technology easily.

In this paper the manufacturing technology study materials can also listen here. The main thing on the exam point of view, students should draw the all diagrams that has been asked on the university examination.
Manufacturing is the production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. Such finished goods may be used for manufacturing other, more complex products, such as aircraft, household appliances or automobiles, or sold to wholesalers, who in turn sell them to retailers, who then sell them to end users and consumers.

Manufacturing takes turns under all types of economic systems. In a free market economy, manufacturing is usually directed toward the mass production of products for sale to consumers at a profit. In a collectivist economy, manufacturing is more frequently directed by the state to supply a centrally planned economy. In mixed market economies, manufacturing occurs under some degree of government regulation.

Modern manufacturing includes all intermediate processes required for the production and integration of a product's components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead.

The manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Electric, Procter & Gamble, General Dynamics, Boeing, Pfizer, and Precision Castparts. Examples in Europe include Volkswagen Group, Siemens, and Michelin. Examples in Asia include Sony, Huawei, Lenovo, Toyota, Samsung, and Bridgestone.
