1、Unit 9 Basic Programming,9.1 Introduction,9.2 Programming Hole Operation,G81 cycle（G81循环） Figure 9.1,Vocabulary,counterbore kauntE5bC: n. 锪孔 simplicity sim5plisiti n. 简单, 简易, 朴素, 直率 take over 接收, 接管 reference plane R点平面，参考平面,Notes,1The simplest operations to program are those related to producing ho
2、les. 与孔加工有关的程序编制是编程中最简单的。,2A fixed cycle, if used properly, takes over and causes the machine to execute the required movements. 如果使用得当的话，固定循环可以接管并指导机床完成所需运动。,3A fixed cycle is programmed by entering in one block of information: the X and Y coordinates, the Z axis reference plane (R), and the final
3、Z axis depth. 固定循环是由一个程序段内的下列信息构成的：X和Y坐标，Z轴参考平面和Z向最终深度。,9.3 Linear Interpolation,Vocabulary,pocket 5pCkit v. 加工凹槽 chamfer 5tFAmfE n. 倒角, 倒棱 bevel 5bevEl n. 斜角, 斜角规, 倾斜, 斜面 taper 5teipE n. 锥形, 锥度,Notes,1While the rapid tool motion is meant to be used from one position of the work area to another posi
4、tion without cutting, the linear interpolation mode is designed for actual material removal, such as contouring, pocketing, face milling and many other cutting motions.,刀具快速运动用于将刀具从工作区的一个位置移动到另一个位置，在这个过程中并不发生切削，而直线插补模式则专门用于实际的材料切除，比如加工轮廓、型腔、铣端面以及许多其他的加工运动。在本句中While 稍有转折含义，表示一个怎样，另外一个是另外一种不同的情况，在翻译中通
5、过“而”字表达这种语气；is meant to be used 和 is designed for 都表示专用于。,2This is a very important programming feature, used mainly in contouring and profiling. Any angular motion (such as chamfers, bevels, angles, tapers, etc.) must be programmed in this mode to be accurate.,这是非常重要的编程特性，主要用于轮廓加工和外形加工。为了准确起见，任何带角度
6、的运动都要在这种模式下编写，比如倒角、斜面、斜线、锥度等。,3The term linear interpolation means that the control system is capable to calculate thousands of intermediate coordinate points between the start point and end point of the cut. The result of this calculation is the shortest path between the two points.,直线插补这个术语的意思是，控制
7、系统能够计算出要加工的起点与终点之间成千上万的中间坐标点，这种运算的结果是得到了两点间的最短路径。,9.3.1 Linear Command,Comparison of the rapid mode and the linear interpolation mode（快速移动模式和直线插补模式的对比） Figure 9.2,Two axes simultaneous linear interpolation motion（两 联动的直线插补运动 Figure 9.3,Three axes simultaneous linear interpolation motion（三轴 联动的直线插补运动
8、） Figure 9.4,Vocabulary,omit Eu5mit vt. 省略, 疏忽, 遗漏 designate 5dezineit vt. 指定, 指派 departure di5pB:tFE n. 启程, 出发, 离开 parallel 5pArElel adj. 平行的, 相同的, 类似的, 并联的 external eks5tE:nl adj. 外部的 internal in5tE:nl adj. 内在的 orthogonal C:5WCEnl adj. 直角的, 直交的 know-how n. 实际知识, 技术秘诀, 诀窍 affordable E5fC:dEbEladj.
9、买得起的,Notes,1This is a very common situation when the start point of the linear motion and its end point have at least two coordinates that are different from each other, while in the linear interpolation mode G01. 在直线插补模式G01中，直线运动的起点和终点之间，至少有不同两个坐标的情况非常普遍。在本句中，while 表示当.的时候。,2Such programming projec
10、ts more than justify an investment into a professional computer based programming system, such as the very powerful and widely used MasterCam, that is based on modern computer technology combined with machining know-how.,这种编程项目最好投资购买专业计算机编程系统，例如功能强大并广泛应用的MasterCam系统，该系统是现代计算机技术和加工技巧的完美结合。,9.3.2 Prog
11、ramming Format,Parameters of G02, G03（G02,G03的参数） Figure 9.5,9.4 Circular Interpolation,Vocabulary,router 5rautE n. 刻模机 burner 5bE:nE n. 气焊机 water jet 水流切割机 laser profiler 激光切割机 radii 5reidiai n. 半径 spherical 5sferikEl adj. 球的, 球形的 conical 5kCnikEl adj. 圆锥的, 圆锥形的 radial 5reidjEl adj. 光线的, 光线状的, 放射状的
12、, 半径的,recess ri5ses n.凹进处 groove ru:v n. 槽，沟 helical 5helikEl adj. 螺旋状的 precision pri5siVEn n. 精确, 精密度, 精度 parameter pE5rAmitE n. 参数, 参量 in effect 有效 modifier 5mCdifaiE n. 限定符，修改者, 更改者, 变址数 priority prai5Criti n. 先, 前, 优先, 优先权,Notes,1Circular interpolation is used for programming arcs or complete ci
13、rcles in such applications as outside and inside radii, circular pockets, spherical or conical shapes, radial recesses, grooves, corner breaks, helical cutting, even large counterbores, etc.,圆弧插补用于编制圆弧和完整的圆，它通常用于加工内外圆、圆柱型腔、球或圆锥、径向凹槽、槽、拐角、螺旋槽、甚至比较大的锪孔等。,2Both the G02 and G03 commands are modal, there
14、fore they remain in effect until the end of program or until canceled by another command, usually by another motion command. G02和G03命令都是模态的，因此它们在程序结束之前都一直有效，除非被另一个命令取消，通常是被另一个运动命令所取消。,3Circular motion in a rapid mode is not possible. Also not possible is a simultaneous three axes circular motion. 圆弧
15、运动不可能在快速模式下进行，也不可能有三轴联动的圆弧运动。,4Control systems supporting the arc radius designation by address R will also accept the IJK modifiers, but the reverse is not true. 如果控制系统支持用地址R来指定半径，一般其也接受IJK限定符的方法，但是反过来则不成立。,Exercises,1Translate the following sentences into Chinese. (1) The controller stores a numbe
16、r of fixed cycles that can be recalled for use in programs when needed. This reduces the programming time and the length of tape required.,(2) The programmed tool motion along any single axis is always a motion parallel to that axis, regardless of the motion mode. (3) A linear motion can also be programmed along two axes simultaneously.,(4) Both the G02 and G03 commands are modal, therefore they remain in effect
