Abstract: The text discuses the importance of the numerical control technology to the whole instry,and analysis the development trend of the numerical control technology and the present condition in domestic and foreign countries .By analyzing the comparing the present condition with foreign countries,it pointes out the direction we should go, and we should develop the high-speed,high finish machining technology , and the intelligently , openly , networkedlily technology , and the setting-up of the new technical standard .
Key words: the numerical control technology ; intelligently ; networkedlily,the new technical standard,the sustainable developmen。

The development of the engineering determins the modernized degree of the whole instry.Marx has ever said " the differences of different economic times, do not lie in what is proced , but lie in how to proce".Manufacturing technology is the most basic means of proction, and numerical control technology is the most central technology of the advanced manufacturing technology. Nowadays the manufacturing instry all around the world adopts numerical control technology extensively, in order to improve manufacturing capacity and level, improve the adaptive capacity and competitive power to the changeable market . In addition every instrially developed country in the world also classifies the technology and numerical control equipment of numerical control as the strategic materials of the country, not merely the great measures to develop one's own numerical control technology, but also implements blockading and restrictive policy to our country in view of " high-grade , precision and advanced key technology of numerical control ". In a word, developing the advanced manufacturing technology taking numerical control technology as the core has already become a important way to accelerate economic development and improve the overall national strength and national position.

摘 要: 本文主要讨论了数控装备对整个工业现代化的重要性,并分析了当前数控技术的发展趋势和国内外数控技术的现状。在对现状的分析和与国外的比较下指出了我国数控技术应该着力发展的方向。着重指出应该向着高速、高精加工,智能化、开放式、网络化,新技术标准的建立发展。
关键词:数控技术,智能化,网络化,规范标准,可持续发展。

装备工业的技术水平决定着整个工业的现代化程度。马克思曾经说过“各种经济时代的区别,不在于生产什么,而在于怎样生产”。制造技术和装备就是人类生产活动的最基本方式,而数控技术又是当今先进制造技术最核心的技术。当今世界各国制造业广泛采用数控技术,以提高制造能力和水平,提高对动态多变市场的适应能力和竞争能力。此外世界上各工业发达国家还将数控技术及数控装备列为国家的战略物资,不仅采取重大措施来发展自己的数控技术,而且在“高精尖”数控关键技术方面对我国实行封锁和限制政策。总之,大力发展以数控技术为核心的先进制造技术已成为世界各发达国家加速经济发展、提高综合国力和国家地位的重要途径。

Crane Work Needs More Technique
Abstract
Crane work needs more technology. Construction of tower cranes are the main vertical transportation equipment and also a measure of construction companies and equipment strength of the important logo, in today's increasingly competitive construction market, to meet the construction needs of many construction companies have bought the tower crane. With the tower crane at the construction site of the widely used by the tower crane accident also caused more and more to people's lives and property brought about great losses. According to national statistics, the departments concerned, the tower crane accident rate reached 2.77 percent. Its security problem is still the urgency of the construction
Loose training, testing and oversight requirements for the people who work around construction cranes have fostered a false sense of security in our instry. The recent deadly tower-crane collapse at a congested New York
City building site should be a wake-up call for us to question and step up our current safety practices.
Training and testing is king when it comes to safety. But the construction instry is putting unqualified personnel in the seats of construction cranes, even with today's testing. In many places, no experience is necessary after passing a standardized test. One week of study will give some people enough knowledge to pass a certification examination, and then they can jump into the cab of a crane.
Imagine that a commercial airline pilot had the same training as a certified crane operator. How would you feel the next time you decided to fly? In California, it takes more hours of training to wield a pair of scissors in a hair salon than to operate potentially dangerous lifting machinery. How does this make sense?
Riggers and signal persons also need standard training and testing to ensure safety under the hook. Employers usually allow any craft to signal a crane on a jobsite, despite best practices that require only qualified people do so. How is it then that uncertified and untrained people are allowed to signal and rig under the hook of a licensed or certified operator?
Tower cranes are particularly risky as urban sites become more congested, and the risk of a catastrophic event is very high ring climbing operations. Yet most tower-crane climbing crews are trained in a non-traditional manner, via secondhand knowledge that has been passed down over time. The problem with this type of hand-me-down knowledge is that it changes over the years, leaving out small-but-important details along the way. This "osmosis" of knowledge leads crews to develop their own tricks for climbing cranes, often forsaking basic safety in an attempt to save time and energy.
In many cases, there are no safety devices or alarms to warn of a serious problem. Climbing crews are subjected to pressures that affect safety-critical decision-making. It is not uncommon for climbs to continue with damaged or leaking hydraulic systems, out-of-adjustment or jammed guide rollers, often working in the dark and for extended hours. This "MacGyver" method of climbing, where every jump becomes a new adventure, should not be the norm.
Climbing-frame designs vary among manufacturers, but the operational steps are similar in principle. The climbing process is relatively straightforward, with a mixture of physical work and technical procere. It is not complex; it is more about knowing the proper sequence of what needs to be done and then following the steps, one by one, making sure each step has been successfully completed before moving onto the next. It is essential that everyone know exactly what is going on and what the dangers are at every stage.
That's why the instry needs standardized training, testing and oversight for this work, including a practical assessment of competence. Technicians should have model-specific training directly from the manufacturer, along with a level of practical experience. Inspectors, too, should be required to have specific technical training. They should be independent from all aspects of installation and maintenance to allow for objective decisions. Key personnel on erection crews should have standard training and testing.
When these needs are satisfied, crane operations should be carried out in strict accordance with the manufacturers' instructions, engineering principals and governmental laws. But instry stakeholders and lawmakers need to step up their lax standards to protect the public. New York City residents, who have seen their homes turned into st and debris, would be shocked at the way the instry deals with these issues.
起重机的工作需要更多的科学技术
摘要

塔式起重机是建筑施工垂直运输的主要设备,也是衡量一个建筑施工企业装备实力的重要标识,在当今竞争日益激烈的建筑市场,为满足施工需要,很多施工企业都购置了塔式起重机。随着塔式起重机在施工现场的广泛使用,由塔式起重机引发的伤亡事故也越来越多,给人民的生命财产带来重大损失。据国内有关部门统计资料表明,塔式起重机的事故率已达2.77%。其安全问题仍然是建筑施工中的忧患……

起重机的工作需要更多的科学技术

松散的培训,测试和监督的要求, 周围的建筑起重机给这些工作的人树立了一种虚假的安全感,在我们的行业。最近塔式起重机倒塌在一个繁忙的纽约市建筑地盘应敲响警钟,提醒我们问题的存在,并加强我们目前安全的做法。
当谈到安全问题时,训练和测试是关键。不过,建造业是把不合格人员放在建筑起重机的驾驶位上,甚至没有通过今天的测试。在许多地方,没有任何经验必须合格的通过标准化的测试。一周的学习将给予一些人足够的知识足以通过认证考试,然后他们可以跳转到的起重机的驾驶室。
想象一下一个商业航空公司飞行员和一个认证的起重机操作员有相同的训练。你会如何感觉,下一次你决定要坐飞机?在加利福尼亚州,掌握一对剪刀在头发沙龙比操作有潜在危险的起重机械需要更多的时间训练。如何,这是否合理?
装配工人和发信号的人也需要标准的培训和测试,以确保安全下钩。雇主通常允许任何工人发信号指挥起重机上工地 ,尽管最佳做法是需要合格的人这样做。怎么能允许那么无证和未受过训练的人来代替有工作证或经核证的操作者呢?
塔式起重机是特别危险的,尤其是在市区用地变得更加拥挤时。攀登行动更是一个风险的行动,其灾难性非常高。然而,大多数塔式起重机攀登员的训练,在一个非传统的方式,通过二手知识已流传一段时间。问题与这种类型的现成的知识是,多年来,留下来的非常少,但最重要的细节却丢失了。这种“渗透”的知识,导致操作者只能发展自己的技巧攀登起重机,往往放弃基本的安全,企图以节省时间和能源.
在许多情况下没有安全装置或警报来提醒严重的问题的存在。攀登人员容易遭受到影响安全性至关重要的决策所带来的压力。攀登时,使用损坏或泄漏的液压系统,没有任何的调整,这并不鲜见。在黑暗中工作和延长工作时间是时有发生的。这种攀登方法,其中的每一次攀登都会成为新的冒险,不应该作为规范被采纳。
攀爬架的设计,在制造商之间存在不同,但设计的步骤在原则上是相似的。攀登过程中是相对比较明了的,配合着的体力劳动和技术程序。这是并不复杂,它是更多地了解知道正确的序列需要做什么,然后按照下列步骤,一个又一个,确保每一步在做下一步前成功完成。这是十分重要,每个人都清楚的知道事情进展的怎么样,在每一个阶段存在什么样的危险。
这就是为什么业界需要规范的培训,测试和监督,其中包括一个实际的评估能力。技术人员应该随着实际经验的提升,直接从制造商哪里获得标准训练。视察员同样也也须有具体的技术培训。他们应独立于安装和维修的各方面,这由客观决定。架设的关键人员应该有标准的训练和测试.
当这些需要得到满足,起重机作业应进行严格按照有关制造商的指示,工程原则和政府的法律。但业内人士和国会议员,要加强他们的宽松标准,以保障公众利益。看到自己的家园变成了尘埃和碎片的纽约市居民,会对处理这些问题的方式感到震惊。

-----------------------------------------------------------
中文翻译得自己做了,实在不成就谷歌翻译。
弄完之后,自己阅读几遍弄顺了就成啦!
学校以及老师都不会看这个东西的!
外文翻译不是论文的主要内容!
所以,很容易过去的!
祝你好运!
