The theoretical reference straight line of the reference guide rail is a straight line in space, so it is straightened on two mutually perpendicular planes (horizontal plane and vertical plane). During the alignment process, the straightness error is also measured in these two planes. The setting of coordinate system is the same as the measurement system.

由于导轨是刚性件，挠度较小，校直幅度不能过大，所以，校直的过程中，直线度误差的计算采用小二乘法。在校直的过程中，是以小二乘中线作为基准直线。在校两条导轨平行程度时，也是采用小二乘中线为基准。导轨和导轨基座的接触是面接触，导轨靠基座上的相互垂直的平面进行定位。校直中，基座接触面增加材料（垫薄片材料）远比去除材料（磨削或刮研）容易，所以，本校直实例采用增加材料（垫薄片材料），但只能达到数丝的精度（垫薄片材料厚度限制），要达到高的精度则需要用去除材料的方法。

As the guide rail is a rigid part, the deflection is small, and the straightening range cannot be too large. Therefore, during the straightening process, the straightness error is calculated by small two multiplication. In the process of straightening, the minor two times the center line is used as the reference line. When checking the parallelism of the two guide rails, the minor two times the center line is also used as the benchmark. The contact between the guide rail and the guide rail base is surface contact, and the guide rail is positioned by the mutually perpendicular planes on the base. In the alignment, it is much easier to add materials (pad sheet materials) to the contact surface of the base than to remove materials (grinding or scraping). Therefore, in this alignment example, the added materials (pad sheet materials) are used, but only the accuracy of several threads (the thickness limit of pad sheet materials) can be achieved. To achieve high accuracy, the method of removing materials is required.

校直过程中的基准直线实际是平行基准导轨小二乘中线并且通过极限点的直线。由于以基准导轨小二乘中线为基准线，为调整方便，选取平行基准线并且通过极限点的直线作为调整的基准，然后计算出各测点相对该调整基准直线的偏移量，按其偏移量进行调整。本校直例中，铅垂面的极限点就是大值；水平面的极限点就是上侧导轨的大值或下侧导轨的小值（去除材料（磨削或刮研）定义极限点是大值和小值互换）。既是以平行小二乘中线且通过该极限点的直线为基准时，调整导轨只需垫薄片材料。

The reference straight line in the straightening process is actually a straight line parallel to the small two times the center line of the reference guide rail and passing through the limit point. Since the small two times the center line of the reference rail is taken as the reference line, the straight line parallel to the reference line and passing through the limit point is selected as the reference line for adjustment, and then the offset of each measuring point relative to the adjustment reference line is calculated and adjusted according to its offset. In this straightening example, the limit point of the vertical plane is the large value; The limit point of the horizontal plane is the large value of the upper guide rail or the small value of the lower guide rail (the limit point defined by material removal (grinding or scraping) is the interchange of the large value and the small value). When the straight line that is parallel to the minor two times the center line and passes through the limit point is taken as the reference, the adjusting guide rail only needs to be padded with sheet material.

具体如下：1.确定基准导轨（由工艺师或生产厂家决定）并进行校直，使其直线度误差的值在规定的范围内；

The details are as follows: 1. Determine the reference guide rail (determined by the technologist or the manufacturer) and straighten it to make its straightness error within the specified range;

2.采用上述的方法校直第二条导轨。以校直好的基准导轨作为基准直线，使第二条导轨的小二乘中线和基准导轨的小二乘中线达到规定的平行度误差。

2. Straighten the second guide rail by the above method. Take the straightened reference guide rail as the reference straight line to make the minor two times center line of the second guide rail and the minor two times center line of the reference guide rail reach the specified parallelism error.
