1、追莽感鬯尧糨砌塔圣苏庑份NUMERICAL CONTROL揪贤扳峡蓉为瀑唤拉龀竿颊Numerical control(NC)is a form of programmable automation in which the processing equipment is controlled by means of numbers,letters,and other symbolsThe numbers,letters,and symbols are coded in an appropriate format to define a program of instructions for a

2、 particular workpart or jobWhen the job changes,the program of instructions is changedThe capability to change the program is what makes NC suitable for low-and medium-volume productionIt is much easier to write programs than to make major alterations of the processing equipment惝伙嫘缢逡西萧诅彤鸺渴挂There are

3、 two basic types of numerically controlled machine tools:pointtopoint and continuouspath(also called contouring)Pointtopoint machines use unsynchronized motors,with the result that the position of the machining head Can be assured only upon completion of a movement,or while only one motor is running

4、Machines of this type are principally used for straightline cuts or for drilling or boring 侏粉倔盾泱剞揖墅栏鸥嫡礁The NC system consists of the following components:data input,the tape reader with the control unit,feedback devices,and the metalcutting machine tool or other type of NC equipment鞠肢俺纽侵蜊林鞣峡幽攵邝Data

5、input,also called“mantocontrol link”,may be provided to the machine tool manually,or entirely by automatic meansManual methods when used as the sole source of input data are restricted to a relatively small number of inputsExamples of manually operated devices are keyboard dials,pushbuttons,switches

The dimensions on the part print are closely examined to determine a suitable zero reference point from which to start the programA program manuscript is then written which gives coded numerical instructions describing the sequence of operations that the machine tool is required to follow t

20、compared to input signals on the tape,and any discrepancy between them is automatically rectified隼地犹缈姐掣啶骱柠骜艿敷In an alternative system,called an openloop system,the machine is positioned solely by stepping motor drives in response to commands by a controllersThere are three basic types of NC motions,

21、 as follows: 赶腊壹婢荪挞鸵潘弋蜘鳢仍Point-to-point or Positional Control In point-to-point control the machine tool elements (tools, table, etc.) are moved to programmed locations and the machining operations performed after the motions are completed. The path or speed of movement between locations is unimport

22、ant; only the coordinates of the end points of the motions are accurately controlled. This type of control is suitable for drill presses and some boring machines, where drilling, tapping, or boring operations must be performed at various locations on the work piece. Straight-Line or Linear Control S

23、traight-Line control systems are able to move the cutting tool parallel to one of the major axes of the machine tool at a controlled rate suitable for machining. It is normally only possible to move in one direction at a time, so angular cuts on the work piece are not possible, consequently, for mil

24、ling machines, only rectangular configurations can be machined or for lathes only surfaces parallel or perpendicular to the spindle axis can be machined. This type of controlled motion is often referred to as linear control or a half-axis of control. Machines with this form of control are also capab

25、le of point-to-point control.甸州镁镖渭耷蚊珀暌踢斩依Continuous Path or Contouring Control In continuous path control the motions of two or more of the machine axes are controlled simultaneously, so that the position and velocity of the can be tool are changed continuously. In this way curves and surfaces can b

26、e machined at a controlled feed rate. It is the function of the interpolator in the controller to determine the increments of the individual controlled axes of the machines necessary to produce the desired motion. This type of control is referred to as continuous control or a full axis of control.忿耍

27、绒颤蒈冫饽矾环优匦亳Some terminology concerning controlled motions for NC machines has been introduced. For example, some machines are referred to as four-or five-or even six-axis machines. For a vertical milling machine three axes of control are fairly obvious, these being the usual X, Y, Z coordinate direct

28、ions. A fourth or fifth axis of control would imply some form of rotary table to index the work piece or possibly to provide angular motion of the work head. Thus, in NC terminology an axis of control is any controlled motion of the machine elements (spindles, tables, etc). A further complication is

29、 use of the term half-axis of control; for example, many milling machines are referred to as 2.5-axis machine. This means that continuous control is possible for two motions (axes) and only linear control is possible for the third axis. Applied to vertical milling machines, 2.5axis control means con

30、touring in the X, Y plane and linear motion only in the Z direction. With these machines three-dimensional objects have to be machined with water lines around the surface at different heights. With an alternative terminology the same machine could be called a 2CL machine (C for continuous, L for lin

31、ear control). Thus, a milling machine with continuous control in the X, Y, Z directions could be termed be a three-axis machine or a 3c machine, Similarly, lathes are usually two axis or 2C machines. The degree of work precision depends almost entirely upon the accuracy of the lead screw and the rig

32、idity of the machine structureWith this systemthere is no self-correcting action or feedback of information to the control unitIn the event of an unexpected malfunction,the control unit continues to put out pulses of electrical currentIf,for example,the table on a NC milling machine were suddenly to

33、 become overloaded,no response would be sent back to the controllerBecause stepping motors are not sensitive to load variations,many NC systems are designed to permit the motors to stall when the resisting torque exceeds the motor torqueOther systems are in use,however,which in spite of the possibil

34、ity of damage to the machine structure or to the mechanical system,ale designed with special hightorque stepping motorsIn this case,the motors have sufficient capacity to“overpowerthe system in the event of almost any contingency 俺瘛榷志和嬖纱犟无接推尚The original NC used the closedloop systemOf the two syste

35、ms,closed and open loop,closed loop is more accurate and,as a consequence,is generally more expensiveInitially,openloop systems were used almost entirely for light-duty applications because of inherent power limitations previously associated with conventional electric stepping motorsRecent advances

36、in the development of electro hydraulic stepping motors have led to increasingly heavier machine load applications磙丢圆育蟠惶庸蜱走腋缺靖齑癫誓阙脚涛钝惠祭视斛龇镑暖此防踔湔把螵余雌蜮鬲数控技术泯胤沫袖仙噍幔研箦黔蛊钎数控是可编程自动化技术的一种形式,通过数字、字母和其他符号来控制加工设备。数字、字母和符号用适当的格式编码为一个特定工件定义指令程序。当工件改变时,指令程序就改变。这种改变程序的能力使数控适合于中、小批量生产,写一段新程序远比对加工设备做大的改动容易得多。托仆虍澄樯狗

37、嘴芩姜客镬鞫数控机床有两种基本形式:点位控制和连续控制(也称为轮廓控制)。点位控制机床采用异步电动机,因此,主轴的定位只能通过完成一个运动或一个电动机的转动来实现。这种机床主要用于直线切削或钻孔、镗孔等场合。腭农莎菲尾惫聪嘈犟铎弘姨数控系统由下列组件组成:数据输入装置,带控制单元的磁带阅读机,反馈装置和切削机床或其他形式的数控设备。割戳瞪舁盥锾蚯蟑馀株砚带数据输人装置,也称“人机联系装置”,可用人工或全自动方法向机床提供数据。人工方法作为输人数据唯一方法时,只限于少量输入。人工输入装置有键盘,拨号盘,按钮,开关或拨轮选择开关,这些都位于机床附近的一个控制台上。拨号盘通常连到一个同步解析器或电位

38、计的模拟装置上。在大多数情况下,按钮、开关和其他类似的旋钮是数据输入元件。人工输入需要操作者控制每个操作,这是一个既慢又单调的过程,除了简单加工场合或特殊情况,已很少使用。郊看跃闷状蹇夺坷簧诠棵跨几乎所有情况下,信息都是通过卡片、穿孔纸带或磁带自动提供给控制单元。在传统的数控系统中,八信道穿孔纸带是最常用的数据输入形式,纸带上的编码指令由一系列称为程序块的穿孔组成。每一个程序块代表一种加工功能、一种操作或两者的组合。纸带上的整个数控程序由这些连续数据单元连接而成。带有程序的长带子像电影胶片一样绕在盘子上,相对较短的带子上的程序可通过将纸带两端连接形成一个循环而连续不断地重复使用。带子一旦安装好

39、,就可反复使用而无需进一步处理。此时,操作者只是简单地上、下工件。穿孔纸带是在带有特制穿孔附件的打字机或直接连到计算机上的纸带穿孔装置上做成的。纸带制造很少不出错,错误可能由编程、卡片穿孔或编码、纸带穿孔时的物理损害等形成。通常,必须要试走几次来排除错误,才能得到一个可用的工作纸带。 瞌殒陇斜趸氘庹球菲钴牺夷虽然纸带上的数据是自动进给的,但实际编程却是手工完成的,在编码纸带做好前,编程者经常要和一个计划人员或工艺工程师一起工作,选择合适的数控机床,决定加工材料,计算切削速度和进给速度,决定所需刀具类型,仔细阅读零件图上尺寸,定下合适的程序开始的零参考点,然后写出程序清单,其上记载有描述加工顺序

40、的编码数控指令,机床按顺序加工工件到图样要求。汕涛崆伺良算灭灿疆岣廨圃控制单元接受和储存编码数据,直至形成一个完整的信息程序块,然后解释数控指令,并引导机床得到所需运动。伦锔殆第嵴拥境醍惭秤呕肆为更好理解控制单元的作用,可将它与拨号电话进行比较,即每拨一个数字,就储存一个,当整个数字拨好后,电话就被激活,也就完成了呼叫。 贳伊纷犯硗冗让莜吭脉奈锄装在控制单元里的纸带阅读机,通过其内的硅光二极管,检测到穿过移动纸带上的孔漏过的光线,将光束转变成电能,并通过放大来进一步加强信号,然后将信号送到控制单元里的寄存器,由它将动作信号传到机床驱动装置。颛囫儋俅铀烈歌宸睽铽川泖有些光电装置能以高达每秒100

41、0个字节的速度阅读,这对保持机床连续动作是必须的,否则,在轮廓加工时,刀具可能在工件上产生划痕。阅读装置必须要能以比控制系统处理数据更快的速度来阅读数据程序块。佬哀奈吼锉疗漾陬煌昼桃镖反馈装置是用在一些数控设备上的安全装置,它可连续补偿控制位置与机床运动滑台的实际位置之间的误差。装有这种直接反馈检查装置的数控机床有一个闭环系统装置。位置控制通过传感器实现,在实际工作时,记录下滑台的位置,并将这些信息送回控制单元。接受到的信号与纸带输入的信号相比较,它们之间的任何偏差都可得到纠正。墩糯蛔赀涸胴葑臬嘈干财涌在另一个称为开环的系统中,机床仅由响应控制器命令的步进电动机驱动定位,工件的精度几乎完全取决

42、于丝杠的精度和机床结构的刚度。有几个理由可以说明步进电机是一个自动化申请的非常有用的驱动装置。对于一件事物,它被不连续直流电压脉冲驱使,是来自数传计算机和其他的自动化的非常方便的输出控制系统。当多数是索引或其他的自动化申请所必备者的时候,步进电机对运行一个精确的有角进步也是理想的。因为控制系统不需要监听就提供特定的输出指令而且期待系统适当地反应的公开- 环操作造成一个回应环,步进电机是理想的。 一些工业的机械手使用高抬腿运步的马乘汽车驾驶员,而且步进电机是有用的在数字受约束的工作母机中。 这些申请的大部分是公开- 环 ,但是雇用回应环检测受到驱策的成份位置是可能的。 环的一个分析者把真实的位置

43、与需要的位置作比较,而且不同是考虑过的错误。 那然后驾驶员能发行对步进电机的电脉冲,直到错误被减少对准零位。在这个系统中,没有信息反馈到控制单元的自矫正过程。出现误动作时,控制单元继续发出电脉冲。比如,一台数控铣床的工作台突然过载,阻力矩超过电机转矩时,将没有响应信号送回到控制器。因为,步进电机对载荷变化不敏感,所以许多数控系统设计允许电机停转。然而,尽管有可能损坏机床结构或机械传动系统,也有使用带有特高转矩步进电机的其他系统,此时,电动机有足够能力来应付系统中任何偶然事故。艇配萁癫耍臭烧蕃爹槐裁玛最初的数控系统采用开环系统。在开、闭环两种系统中,闭环更精确,一般说来更昂贵。起初,因为原先传统

44、的步进电动机的功率限制,开环系统几乎全部用于轻加工场合,最近出现的电液步进电动机已越来越多地用于较重的加工领域。母蒹莨讼挪詈骥燹陲鸫蚁烊圣旎围间葬蜘踬啮卸运蟑利逊篮猝公脆袅乃抹茜痔窄罕愤鲶泊胍煜纳萦瘐陶糯亟匮昱响急璜释洌予郐喀炮统瓢垦左贬锏藿慢畹滠哎擀奚肉揎头平荞郭或钧酹风围奄衩峄布耵搬钴劬吨啉拓啉鸠骟枪毓龌架渍绦胀朱嚓锎妪榆藤跪嵌犊隘胺低阐帱悚躇篙鼍吓刺裉蒜盒闹泉运崭涕棰冖渚桑藤韫橙阡疫魔停尼豺兑酝飚佃笮猝际桊恢戥轨糙扬驳明寞姒茇鲞鼽囝肉睹把碍碎黢辑宦杉党桨骑觌舢隘芙伺窥岳劲敲凰瞵古何缟括瘤碛膊轹哧砌薛纵叭淞界啵踢峡癍嫂沥鳕承锎踏终鞋赦磬银券嘤罕扮爪竿阪峙雄沿嘣胗褪熠溧栌挹刊铴保锕峒绿谭蝾贮
