摘要： The runout or profile of parts is measured without the need for precision supports by rotating the part generally about an axis of rotation. The changes in position of one or more reference surfaces on the part along first and second tracking axes are measured for a plurality of rotational positions of the part. The change in position of the target surface for which the runout or profile is to be determined is measured along a third tracking axis which lies substantially in a common plane with the first and second tracking axes. The change in position of the rotational axis of the part along the third tracking axis is determined from the changes in position of the one or more reference surfaces and the distances between the tracking axes, and is subtracted from the measured change in position of the target surface along the third tracking axis to determine the runout or profile. Independent measurement devices, which can be aligned to the vertical using a level when the tracking axes are horizontal comprise a transmitter generating a plane of laser energy extending along and perpendicular to the tracking axis and a receiver which detects the change in the portion of the plane of laser energy blocked by the surface being tracked.
摘要翻译：通过围绕旋转轴旋转部件来测量部件的跳动或轮廓，而不需要精密支撑。针对部件的多个旋转位置测量沿着第一和第二跟踪轴的部件上的一个或多个参考表面的位置的变化。沿着与第一和第二跟踪轴基本上在公共平面中的第三跟踪轴测量要确定跳动或轮廓的目标表面的位置变化。沿着第三跟踪轴的部件的旋转轴的位置的变化根据一个或多个参考表面的位置的变化和跟踪轴之间的距离来确定，并且从测量的目标位置的变化中减去沿着第三个跟踪轴的曲面以确定跳动或轮廓。当跟踪轴水平时，独立的测量装置可以使用水平对准垂直方向，包括产生沿跟踪轴线并垂直于跟踪轴线延伸的激光能量平面的发射器，以及检测该平面部分变化的接收器的激光能量被被跟踪的表面阻挡。
