第五章座标定位系统座标定位系统,是用座标镗床或座标磨床工作台的直线运动控制工件位置的一种手段。其中,工作台是由测量系统来控制的,这个系统是建立在第三章提到过的基准平面、垂直度和线值测量基础上的。这个系统与在图板上标定的工件尺寸系统是相同的。为了易于理解这一点,可举一例来说明这个系统本质上是何等的简单和适用。图纸上的尺寸一经注出,这些 Chapter 5 Coordinate Positioning System Coordinate Positioning System is a means of controlling the position of the workpiece by the linear motion of a coordinate boring machine or a coordinate grinder table. Among them, the workbench is controlled by the measurement system, which is based on the reference plane, verticality and line measurement mentioned in chapter III. This system is identical to the part size system calibrated on the board. To make this easy to understand, give an example of how simple and useful this system is by nature. Once the dimensions on the drawing are noted, these
