# How To Determine The Ideal Plane Orientation Of a Cast Iron Flat Plate?

Nov. 02 , 2018

1, the principle of small conditions

The actual Cast Iron Flat Plate surface is accommodated by two parallel ideal planes, and the distance between the two ideal planes is small, which is the flatness error value.

2, the principle of appropriate

Using an ideal plane tangent to the actual surface, and the large distance from the actual surface is small, this distance is the flatness value

3. The principle of small squares

The ideal plane is placed in the middle of the actual surface according to the trend of the actual surface, and the sum of the squares of the points on the actual surface to the ideal plane is small. The center plane of the small square is used as the evaluation base, and each measuring point The difference between the large value and the small value in this plane deviation is the flatness error value of the measured surface.

4, diagonal principle

The plane parallel to the other diagonal line passing through a diagonal line of the measured surface is used as the evaluation base surface, and the difference between the large value and the small value of the plane deviation of each measurement point is the flatness error value of the measured surface.

5, the principle of the ring method

By measuring the principle of the closed loop, the distance from the new position after the measured points to the measuring base becomes the distance of each point from the ideal plane. At this time, the ideal plane is the natural level passing through the origin.

6, the three-point principle

The plane defined by the three points on the actual Cast Iron Floor Plates surface that are far apart from each other on a straight line is the evaluation base surface, and the difference between the large value and the small value in the deviation of each measurement point from the plane is the flatness of the measured surface. difference.

7, the principle of large straightness

The straightness error of any cross section of the actual surface is taken as the flatness error value. Copyright © Willing Measuring Tools Co. Ltd All Rights Reserved Sitemap | Powered by
