PERSONAL COMPUTERS

The personal computer can serve as a work station for the individual today. Moreover, as it has become financially feasi­ble to provide a computer for the individual worker, so also tech­nical developments have made the interface between man and machine increasingly "friendly", so that a wide array of com­puter functions are now accessible to people with no technical background.

A personal computer is a small computer based on a micro­processor; it is a microcomputer. Not all computers, however, are personal computers. A microcomputer can be dedicated to a single task such as controlling a machine tool or metering the injection of fuel into an automobile engine; it can be a word processor, a video game or a "pocket computer" that is not quite a computer. A personal computer is something different: a stand­alone computer that puts a wide array of capabilities at the dis­posal of an individual.

The first generation of true personal computers, which came on the market between 1977 and 1981, had eight-bit micropro­cessors; later introduced systems had 16-bits ones. Now 32-bit microprocessor chips are available, and soon they will be includ­ed in complete computer systems.

AUTOMATION AND ROBOTICS

«AUTOMATION»

Automation is the system of manufacture perform­ing certain tasks, previously done by people, by machines only. The sequences of operations are controlled auto­matically. The most familiar example of a highly auto­mated system is an assembly plant for automobiles or other complex products.

The term automation is also used to describe nonma-nufacturing systems in which automatic devices can op­erate independently of human control. Such devices as automatic pilots, automatic telephone equipment and automated control systems are used to perform various operations much faster and better than could be done by people.

Automated manufacturing had several steps in its development. Mechanization was the first step necessary in the development of automation. The simplification of work made it possible to design and build machines that resembled the motions of the worker. These specialized machines were motorized and they had better production efficiency.

Industrial robots, originally designed only to perform simple tasks in environments dangerous to human work­ers, are now widely used to transfer, manipulate, and position both light and heavy workpieces performing all the functions of a transfer machine.

In the 1920s the automobile industry for the first time used an integrated system of production. This method of production was adopted by most car manufacturers and became known as Detroit automation.

The feedback principle is used in all automatic-con­trol mechanisms when machines have ability to correct themselves. The feedback principle has been used for centuries. An outstanding early example is the flyball governor, invented in 1788 by James Watt to control the speed of the steam engine. The common household ther­mostat is another example of a feedback device.

Using feedback devices, machines can start, stop, speed up, slow down, count, inspect, test, compare, and measure. These operations are commonly applied to a wide variety of production operations.

Computers have greatly facilitated the use of feedback in manufacturing processes. Computers gave rise to the development of numerically controlled machines. The motions of these machines are controlled by punched paper or magnetic tapes. In numerically controlled ma­chining centres machine tools can perform several dif­ferent machining operations.

More recently, the introduction of microprocessors and computers have made possible the development of computer-aided design and computer-aided manufacture (CAD and CAM) technologies. When using these systems a designer draws a part and indicates its dimensions with the help of a mouse, light pen, or other input device. Af­ter the drawing has been completed the computer automatically gives the instructions that direct a machining centre to machine the part.

Another development using automation are the flex­ible manufacturing systems (FMS). A computer in FMS can be used to monitor and control the operation of the whole factory.

Automation has also had an influence on the areas of the economy other than manufacturing. Small comput­ers are used in systems called word processors, which are rapidly becoming a standard part of the modern office. They are used to edit texts, to type letters and so on. Automation in Industry

Many industries are highly automated or use automa­tion technology in some part of their operation. In com­munications and especially in the telephone industry di­alling and transmission are all done automatically. Rail­ways are also controlled by automatic signalling devices, which have sensors that detect carriages passing a par­ticular point. In this way the movement and location of trains can be monitored.

Not all industries require the same degree of automa­tion. Sales, agriculture, and some service industries are difficult to automate, though agriculture industry may become more mechanized, especially in the processing and packaging of foods.

The automation technology in manufacturing and as­sembly is widely used in car and other consumer product industries.

Nevertheless, each industry has its own concept of automation that answers its particular production needs.

"TYPES OF AUTOMATION»

Applications of Automation and Robotics in Industry

Manufacturing is one of the most important applica­tion area for automation technology. There are several types of automation in manufacturing. The examples of automated systems used in manufacturing are described below.

1. Fixed automation, sometimes called «hard automa­tion» refers to automated machines in which the equip­ment configuration allows fixed sequence of processing operations. These machines are programmed by their design to make only certain processing operations. They are not easily changed over from one product style to another. This form of automation needs high initial in­ vestments and high production rates. That is why it is suitable for products that are made in large volumes. Examples of fixed, automation are machining transfer lines found in the automobile industry, automatic assem­bly machines and certain chemical processes.

2. Programmable automation is a form of automation for producing products in large quantities, ranging from several dozen to several thousand units at a time. For each new product the production equipment must be reprogrammed and changed over. This reprogramming and changeover take a period of non-productive time. Pro­duction rates in programmable automation are generally lower than in fixed automation, because the equipment is designed to facilitate product changeover rather than for product specialization. A numerical-control machine-tool is a good example of programmable automation. The program is coded in computer memory for each differ­ent product style and the machine-tool is controlled by the computer programme.

3. Flexible automation is a kind of programmable au­tomation. Programmable automation requires time to re-program and change over the production equipment for each series of new product. This is lost production time, which is expensive. In flexible automation the number of products is limited so that the changeover of the equip­ment can be done very quickly and automatically. The reprogramming of the equipment in flexible automation is done at a computer terminal without using the pro­duction equipment itself. Flexible automation allows a mixture of different products to be produced one right after another.

«ROBOTS IN MANUFACTURING»

Today most robots are used in manufacturing opera­tions. The applications of robots can be divided into three categories:

1. material handling

2. processing operations

3. assembly and inspection.

Material-handling is the transfer of material and load­ing and unloading of machines. Material-transfer appli­cations require the robot to move materials or work parts from one to another. Many of these tasks are relatively simple: robots pick up parts from one conveyor and place them on another. Other transfer operations are more complex, such as placing parts in an arrangement that can be calculated by the robot. Machine loading and un­loading operations utilize a robot to load and unload parts. This requires the robot to be equipped with a grip-per that can grasp parts. Usually the gripper must be designed specifically for the particular part geometry.

In robotic processing operations, the robot manipu­lates a tool to perform a process on the work part. Exam­ples of such applications include spot welding, continu­ous arc welding and spray painting. Spot welding of au­tomobile bodies is one of the most common applications of industrial robots. The robot positions a spot welder against the automobile panels and frames to join them. Arc welding is a continuous process in which robot moves the welding rod along the welding seam. Spray painting is the manipulation of a spray-painting gun over the sur­face of the object to be coated. Other operations in this category include grinding and polishing in which a ro­tating spindle serves as the robot's tool.

The third application area of industrial robots is as­sembly and inspection. The use of robots in assembly is expected to increase because of the high cost of manual labour. But the design of the product is an important aspect of robotic assembly. Assembly methods that are satisfactory for humans are not always suitable for ro­bots. Screws and nuts are widely used for fastening in manual assembly, but the same operations are extremely difficult for a one-armed robot.

Inspection is another area of factory operations in which the utilization of robots is growing. In a typical inspection job, the robot positions a sensor with respect to the work part and determines whether the part answers the quality specifications. In nearly all industrial robotic applications, the robot provides a substitute for human labour. There are certain characteristics of industrial jobs performed by humans that can be done by robots:

1. the operation is repetitive, involving the same ba­sic work motions every cycle,

2. the operation is hazardous or uncomfortable for the human worker (for example: spray painting, spot weld­ing, arc welding, and certain machine loading and un­loading tasks),

3. the workpiece or tool are too heavy and difficult to handle,

4. the operation allows the robot to be used on two or three shifts.

Vocabulary:

handling — обращение

transfer — передача, перенос

location — местонахождение

pick up — брать, подбирать

arrangement — расположение

to utilize — утилизировать, находить при­менение

gripper — захват

to grasp — схватывать

spot welding — точечная сварка

continuous — непрерывный

arc welding — электродуговая сварка

spray painting — окраска распылением

frame — рама

spray-painting gun — распылитель краски

grinding — шлифование

polishing — полирование

spindle — шпиндель

manual — ручной

labour — труд

hazardous — опасный

shift — смена

FAMOUS PEOPLE OF SCIENCE AND ENGINEERING

James Watt

James Watt was a Scottish inventor and mechanical engineer, known for his improvements of the steam en­gine.

Watt was born on January 19, 1736, in Greenock, Scotland. He worked as a mathematical-instrument maker from the age of 19 and soon became interested in improving the steam engine which was used at that time to pump out water from mines.

Watt determined the properties of steam, especially the relation of its density to its temperature and pres­sure, and designed a separate condensing chamber for the steam engine that prevented large losses of steam in the cylinder. Watt's first patent, in 1769, covered this device and other improvements on steam engine.

At that time, Watt was the partner of the inventor John Roebuck, who had financed his researches. In 1775, however, Roebuck's interest was taken over by the manu­facturer Matthew Boulton, owner of the Soho Engineer­ing Works at Birmingham, and he and Watt began the manufacture of steam engines. Watt continued his re­search and patented several other important inventions, including the rotary engine for driving various types of machinery; the double-action engine, in which steam is admitted alternately into both ends of the cylinder; and the steam indicator, which records the steam pressure in the engine. He retired from the firm in 1800 and there­after devoted himself entirely to research work.

The misconception that Watt was the actual inventor of the steam engine arose from the fundamental nature of his contributions to its development. The centrifugal or f lyball governor, which he invented in 1788, and which automatically regulated the speed of an engine, is of par­ticular interest today. It embodies the feedback princi­ple of a servomechanism, linking output to input, which is the basic concept of automation. The watt, the unit of power, was named in his honour. Watt was also a well-known civil engineer. He invented, in 1767, an attach­ment that adapted telescopes for use in the measurement of distances. Watt died in Heathf ield, near Birmingham, in August 1819.
