IntroductionMachining aims to generate the shape of work-piece form a solid body,or to improve the tolerances and surface finish of a previously formed work-piece,by removing excess materials in the form of chips. Machining is capable of creating geometric configurations,tolerances, and surface finishes often unobtainable by any other r, machining removes materials, which has already been paid for, in the form of relatively small particles that are more difficult to recycle and are in greater danger of becoming mixed. Therefore,developments often aim at reducing or-if at all possible-eliminating machining, especially in mass these reasons, machining has lost some important markets, yet, at the same time, it has also been developing and especially having captured new markets with the application of numerical feel for the important of machining may be gained from the observation that in 1983 there were about 2 million metal-cutting machine tools in the unite states ( of which some 5% were numerically controlled ) and that labor and overhead costs amounted to $125 billion, or 3% of the GNP.

摘要- Cobots是一类机器人的使用不断
无级变速发展高保真可编程
约束的表面。 Cobots消耗很少的电力
即使在提供高输出部队,其传输效率高众多的
传动比。 Cobotic变速箱也有能力
采取行动作为一个制动器或将成为完全免费。设计
和性能Cobotic手控制器,最近
发达国家六自由度触觉显示器,是审查。
这个装置表明,高动态范围和低功耗
消费实现的cobots 。彻底的比较
电源效率cobotic系统与传统的
机电系统提供。
三个关键要求机器人技术用于
假肢和康复是低体重,低功耗

车削机床
机床工具被广泛用于工业,以生产各类机械零件。有些是一般用途的机器,和其他人用来执行高度专业化的操作。使用最广泛的机床是普通车床,它提供了一个旋转轴的主要原则的议案,同时适当传授饲料动议的工具。的工件,必须牢牢掌握,经常在一个夹头。酒吧也可举行collets ,其中包含一个分裂套管推或拉对锥面。工件形状的尴尬往往是由螺栓的面板。
包含的启闭机制的驱动器,通常将改变齿轮和变速驱动器。长期工件支持他们最后提出了中心举行尾座。这个工具本身是一个工具举行后,允许设置工具的角度(横向和纵向) 。该工具后是安装在一个马车,而这反过来又获得支持的方式加工的床,确保刚性和免受震动。悬垂部分,停机坪的运输,可从事与饲料棒给予连续进给运动,或与丝杠切割的线程。很长工件的担保反对过度偏转的两个手指中心稳步休息休息或螺栓的车床床;后续其余贴近马车。
有时工具后坐在复合刀架其中包括幻灯片,可以设置在任何角度,因此,圆锥表面可以通过手喂养工具。参观双向工具后可旋转约竖井,并允许快速变化的工具,在预设的立场,从而加快连续行动
示踪剂或重复车床的设计制造形状不规则零件自动。基本操作这一车床如下。模板的任何一个单位或三维形状是放置在一个时段。阿导或指针然后继续沿着这条形状和其运动控制的切削刀具。重复可能包括方形或锥形,肩膀,半径,沟槽,蜡烛,和轮廓,工作,如电机轴,主轴,价值茎,活塞,杆,汽车车轴,涡轮轴,以及各种其他的物体也可以打开使用这种类型的车床。转塔车床的生产车床是用来制造任何数量的相同件。
螺杆机类似的建设炮塔车床,但他们的头上旨在保持和饲料长期酒吧的股票。否则,没有什么区别。
有些地方不太通顺,自己修改一下就OK了。

In view of the pivotal role of rolling bearing in rotating machinery and equipment, it is very important to diagnose the fault, and it is the best way and means to establish a set of efficient and convenient bearing fault diagnosis system. Most of the traditional diagnostic system depends on a number of professional hardware equipment, these instruments are obviously difficult to meet the requirements of information technology, and caused a lot of hardware redundancy. With the rapid development of computer technology, the virtual instrument technology has been applied to the field of bearing fault diagnosis has become a trend. This paper introduces the characteristics and structure of virtual instrument technology. On this basis, the resonance demodulation technique is introduced into the signal analysis of virtual instrument to extract and analyze the bearing fault signal. Finally, based on LABVIEW platform, a set of virtual instrument for bearing fault signal analysis is developed.
