测量
    The width measurement is performed by two 2D top lighting sensors aiming vertically on both edges of the product.
    宽度测量是由两个2D顶部照射传感器垂直对准产品的两侧实现的。
    After compare of several traditional ways, we use the ray axis approach based on the digital image processing, and design mechanical structure. Sensitivity and speed of measurement is improved by using the optical enlargement principle, beam splitter and CCD camera.
    本文对空间直线度的测量方法和数据处理进行了探讨,通过对各种方法的比较,确定了采用基于数字图像处理的光轴法的检测方法,设计了该测量方法的机械结构方案,利用光学反射放大原理,分光镜和CCD摄像机的使用提高了检测的灵敏度,也使得测量过程的自动化大大提高,从而提高了测量速度。
    Due to the average effect among the measuring units, the error of the measurement is(0.005+1×10 -5 D) mm or less for those cones with small coning angle.
    由于各测量单元的平均化作用,当测量小锥度端面直径时,测量误差仅为(0 .005+ 1 ×10-5 D) mm 。
    The uncertain degree of measurement is the perfection and developing of error theory, the subject of itsanalysis remains the error.
    测量不确定度是误差理论的完善和发展,其分析的主体仍然是误差。
    It can be found out from their definition, uncertain degree states the more ability tomeasure quality than the error in measurement, the uncertain degree of measurement is more overall and moreconcrete than the error.
    从它们的定义可以看出,测量不确定度比误差更具有说明测量质量好坏的能力,测量不确定度比误差更全面更具体。
    When spur gears whose diameters of indexing circle are less than 5 mm are measured by CCD camera with the resolution of over 1280×1024, the precision of measurement is below than 2 μm.
    如使用1280×1024像素以上的CCD摄像设备测量分度圆直径5mm以下的直齿圆柱齿轮时,测量精度可在2μm以下。
    The method that combining RENISHAW MP10/OMP60 probe system and SIEMENS 840D CNC system to realize workpiece or tool measurement is expatiated, including the hardware connection, software setup, parameter setup and application of measuring cycles.
    详细阐述了雷尼绍MP10/OMP60测头系统结合西门子840D数控系统实现工件/刀具测量的方法,包括硬件连接、软件设置、参数设置和测量循环的应用。
