Section II Text
Early in the 1950s, two important engineering discoveries changed th e image of the electronic-computer field. These discoveries were the mag netic core memory and Transistor-Circuit Element. These technical disco veries quickly found their way into new models of digital computers. In the 1960s, efforts to design and develop the fastest possible compu ter with the greatest capacity reached a turning point with the LARC mac hine. The LARC had a base memory of 98000 words and multiplied in 1 0 μs. The trend during the 1970s was, to some extent, moving away from ve ry powerful, single-purpose computers and toward a larger range of appli cations for cheaper computer systems. Most continuous-process manufac turing, such as petroleum refining and electrical-power distribution syste ms then used computers of smaller capability for controlling and regulati ng their jobs.

《机电专业英语》 教学课件课件 Unit 24 Flexible Manufacturing
A flexible manufacturing system (FMS) is a highly automated GT machine cell, consisting of a group of processing workstations (usually CNC machine tools), interconnected an automated material handling and storage system. The reason the FMS is a called flexible is that it is capable of processing a variety of different part styles simultaneously at the various workstations, and the mix of part styles and quantities of production can be adjusted in response to changing patterns demanded. The FMS is most suited for the mid-variety, midvolume production range.
1. Computer control. 2. Automated materials handling capability. 3. Tool handling capability.
Text & Translation
Flexible manufacturing was first introduced in the mid-1960s when the British firm Moils Ltd. developed its System 24. System 24 is a real FMS. However, it was doomed from the outset because automation, integration, and computer control technology had not yet been developed to the point where they could properly support the system. With the emergence of sophisticated computer control technology in the late 1970s and 1980s, flexible manufacturing became a viable concept. In the United States, manufacturers of automobiles, trucks, and tractors are the pioneers in adopting flexible manufacturing.

Unit11FundamentalsofMaterialForming机电专业英语图文课件
Text & Translation
Group III—Separating. Machining or removal of material，that is，destroying cohesion.
Group IV—Joining. Uniting of individual workpieces to form filling subassemblies，filling and impregnating of workpieces，and so on，that is， increasing cohesion between several workpieces.
Text & Translation
2. Principles of Plastic Forming Plasticity theory is the foundation for the numerical
treatment of metal forming processes. Materials science and metallurgy can explain the origins of the plastic state of metallic bodies and its dependence on various parameters，such as process speed，prior history，temperature. The essentially older plasticity theory deals with the calculation of stresses，forces，and deformation.

Unit-7-Lathes-机电专业英语-图文课件
1.Engine Lathes ［1］Engine lathes，of course，are general purpose
machines used in production and maintenance shops all over the world. Sizes range from small bench models to huge heavy duty pieces of equipment. Many of the larger lathes are equipped with auxiliary parts which are not commonly available in ordinary shops，such as automatic stops for the carriage.
Text & Translation
The first screw machines were designed to feed bar stock and wire used in making small screw parts. At present，however， the turret lathe is frequently used with a collet attachment，and the automatic screw machine can be equipped with a chuck to hold castings.
Text & Translation
In the single spindle automatic screw machine，a specific length of stock is automatically fed through the spindle to a machining area. At this point，the turret and cross slide move into position and automatically perform whatever operations are required. After the machined piece is cut off，stock is again fed into the machining area and the entire cycle is repeated.
