三、圆度误差的检测及评定方法 1.半径测量法。使被测横截面实际轮廓绕其中心回转一周,测得其半径的变动量,以测定其圆度误差的方法。常用有以下两种方法: 圆度仪法。圆度仪是检测圆度误差的专用最仪,以其精密的回转主轴轴线作为测量基准,直接测出被测截面的实际轮廊,测量方法如图1所示。将被测零件固定到工作台上,选择适当的测杆长度、测头半径,使测头与被测零件表面接触。调整零件位置,使测量截面与圆度仪主轴轴线垂直,轴线对
Third, the roundness error detection and evaluation methods 1 radius measurement method. The actual cross-section of the measured profile around the center of a revolution, measured the amount of variation of its radius to measure the roundness error method. There are two commonly used methods: roundness meter method. Circularity meter is a special instrument for detecting the roundness error, and its precise rotary spindle axis is used as the measurement reference to directly measure the actual contour of the measured section. The measurement method is shown in Fig.1. The measured part is fixed to the table, select the appropriate rod length, the probe radius, the probe and the measured surface contact. Adjust the position of the part so that the measuring section is perpendicular to the spindle axis of the roundness meter and the axis is right
