Mechanical Engineering Specialities


Engineering is a broad discipline which is broken down into several subdivisions. These disciplines concern with different areas of engineering work.

Engineering is one of the most ancient occupations of people. It is defined as the science of building and controlling machines, houses, ships, locomotives, motor vehicles, machine - tools, roads, bridges, etc. Engineering presupposes the connection of theoretical sciences with practical application. As time went on, engineering specialities were widening and now there exist not only mechanical, civil, mining, metallurgical, military, chemical, electrical engineering, but also aerospace, nuclear, petroleum and electronic one.

The approximate division of engineering fields may be as follows:

1. mechanical engineering – the design of physical or mechanical systems, such as steam engines, internal combustion engines, turbines, pumps, compressors, machine tools, mechanisms, power trains, kinematic chains and vibration isolation equipment;

2. electrical engineering – in its turn is subdivided into two branches: a) power engineering dealing with generators, motors, transformers, transmissions, and b) electronics dealing with radio, radar, television;

3. civil engineering encompassing the design and construction of public and private works, such as dams, tunnels, roads, infrastructure, bridges and buildings;

4. structural engineering - creating structural details of machines and mechanism and buildings;

5. chemical engineering – is the conversion of raw materials and various substances and compounds into usable commodities;

6. aerospace (aeronautical)engineering is dedicated to design of aircrafts and spacecrafts.

With the rapid advancement of technology many new fields are gaining prominence and new branches are developing: computer engineering, software engineering, nanotechnology, molecular engineering, mechatronics, etc. These new specialities sometimes combine with the traditional fields and form new branches such as mechanical engineering and mechatronics and electrical and computer engineering. For each of these fields there exists considerable overlap, especially in the areas of the application of sciences to such disciplines as physics, chemistry and mathematics.

The growth in the number of engineering fields resulted in the growth of the large number of different kinds of engineers: metallurgists, the strength of materials experts, thermodynamics of heat experts, hydrodrive experts, cryogenics experts, tool designers and others. The specialists’ work in various branches of engineering requires special knowledge, proper education and good training. Each specialist should become more scientific and specialized. Improvements in engineering field largely depend on the application of science to manufacture. This is possible in the case of availability of large number of scientifically trained engineers. Therefore, there is a growing need for engineers who are familiar with the fundamental problems in metal processing and manufacturing. Mechanical engineers make the vast contribution to production by designing products, various components and materials, alloys by developing new products and production processes, equipment and devices, tools, assembly fixtures and so on.

Below several short definitions of some engineering specialities are given:

Engineer – a person who studies, plans, designs, develops and builds machines.

Mechanic – a skilled workman, one who makes or uses machinery.

Technologist – one who has studied technology, the science which deals with industrial arts.

Turner – one who works with a lathe.

Fitter – a mechanic who puts together parts of a machine.

Plumber – a man who fits and mends water-pipes, sanitary devices, etc.

Repairman – a person who mends, restores things to a perfect condition.

Machinist – one who makes, controls or repairs machinery.

Locksmith – one who makes and repairs locks.

Grinder – a person who grinds, polishes and cuts metals and other materials.

Miller – is that who cuts, shapes and threads parts with mechanical tools.

Electrician – a person who makes, manages, controls or repair electric machinery.

Operator – is one who handles, controls devices, equipment and machinery.

Metallurgist – one who is skilled in metallurgy, the art and science of preparing metals for use by separating them from ores, making them pure and casting various alloys.

Welder – the worker who joins together two pieces of metal in hot condition.

Technician – the person who deals with industrial branch, an expert in engineering.
