Development of machines for the production of goods the high material standard of living in the developed countries owes much to the machinery made possible by mechanical engineering.The mechanical engineer continually invents machines to produce goods and develops machine tools of increasing accuracy and complexity to build the machines.The principal lines of development of machinery have been an increase in the speed of operation to obtain high rates of production,improvement in accuracy to obtain quality and economy in the product,and minimization of operating costs.These three requirements have led to the evolution of complex control systems.The most successful production machinery is that in which the mechanical design of the machine is closely integrated with the control system,whether the latter is mechanical or electrical in nature.A modern transfer line (conveyor) for the manufacture of automobile engines is a good example of the mechanization of a complex series of manufacturing processes.Developments are in hand to automate production machinery further,using computers to store and process the vast amount of data required for manufacturing a variety of components with a small number of versatile machine tools.One aim is a completely automated machine shop for batch production,operating on a three shift basis but attended by a staff for only one shift per day.Development of machines for the production of power Production machinery presuppose an ample supply of power.The steam engine provided the first practical means of generating power from heat to augment the old sources of power from muscle,wind,and water One of the first challenges to the new profession of mechanical engineering was to increase thermal efficiencies and power; this was done principally by the development of the steam turbine and associated large steam boilers.The 20th century has witnessed a continued rapid growth in the power output of turbines for driving electric generators,together with a steady increase in thermal efficiency and reduction in capital cost per kilowatt of large power stations.Finally,mechanical engineers acquired the resource of nuclear energy,whose application has demanded an exceptional standard of reliability and safety involving the solution of entirely new problems-The control systems of large power plank and complete nuclear power stations have become highly sophisticated networks of electronic,fluidic.Electric,hydraulic,and mechanical components,ail of these involving me province of the mechanical engineer.

开发的机器生产的商品的高物质生活水平在发达国家在很大程度上归功于机械成为可能,机械工程系.不断的机械工程师发明的机器生产货物和开发数控机床的精度和复杂性日益增加,以建立机.主要线路的发展机制已经增加的速度运行,以获得较高的产量,改善准确性获得质量和经济的产品,并尽量减少营运成本.这三个要求导致的演化复杂的控制系统.最成功的生产机械的是,其中机械设计的机器是紧密结合的控制系统,无论后者是机械或电力的nature.A现代传输线（输送）用于制造汽车发动机是一个很好的例子机械化的一系列复杂的制造工艺.发展是在手自动化生产机械,进一步利用计算机存储和处理大量数据所需要的制造各种各样的组成部分少数多功能机床.目的之一是一个完全自动化的车间成批生产,经营的三个转变的基础,但工作人员参加了只有一个班次,一个班次每天.开发的机器生产的电力生产机械假定供应充足的电力.蒸汽机提供了第一个实用的手段,热发电,以加强旧动力源来自肌肉,风和水的第一个挑战,新的专业是机械工程,提高热效率和功率;这样做主要是发展的汽轮机和相关大型汽轮机boilers.The 20世纪出现了持续快速增长的动力输出驱动的涡轮发电机,同时不断增加,热效率和降低资本成本每千瓦大型电站.最后,机械工程师获得了资源的核能源,其应用的特殊要求标准的可靠性和安全性的解决方案涉及的完全新的问题,控制系统的大型电力木板和完整的核电站已成为非常先进的网络电子,流体.电气,液压和机械部件,艾里这些涉及我省的机械工程师.
