1、最小條件原則用兩個(gè)平行的抱負平面包涵現實(shí)外貌，并使兩抱負平面間的間隔為最小，此最小間隔為平面度偏差值。
2、貼切原則用一個(gè)抱負平面與現實(shí)外貌相切，且與現實(shí)外貌之間的最大間隔為最小，此間隔為平面度值
3、最小二乘方原則將一個(gè)抱負平面按現實(shí)外貌的趨勢，置于現實(shí)外貌的中部，并使現實(shí)外貌上各點(diǎn)到抱負平面的間隔平方和為最小，以這個(gè)最小二乘方中央平面作為評定基面，各測點(diǎn)對此平面偏差中最大值與最小值之差為被測外貌平面度偏差值。
4、鑄鐵平臺對角線(xiàn)原則以通過(guò)被測外貌的一條對角線(xiàn)而平行于另一條對角線(xiàn)的平面作為評定基面，各測點(diǎn)對此平面偏差中最大值與最小值之差為被測面平面度偏差值。
5、環(huán)線(xiàn)法原則利用丈量閉合環(huán)的平差原理，使各被測點(diǎn)平差后的新位置到丈量基面的間隔變?yōu)楦鼽c(diǎn)相對付抱負平面的間隔。這時(shí)抱負平面便是通過(guò)原點(diǎn)的天然程度面。
6、三點(diǎn)法原則劃定抱負平面通過(guò)現實(shí)外貌上相距最遠且不在一條直線(xiàn)上的三點(diǎn)形成的平面為評定基面，以各測點(diǎn)距此平面偏差中最大值與最小值之差為所求被測外貌的平面度偏差值。
7、最大直線(xiàn)度原則以現實(shí)外貌任一截面最大直線(xiàn)度偏差作為平面度偏差值。
鑄鐵平板和鑄鐵平臺的局部偏差
鑄鐵平板(鑄鐵平臺)的局部偏差是指平板事情面局部平面度加工質(zhì)量，包羅事情面加工的微觀(guān)質(zhì)量和事情面小范疇內的局部畸變。所謂加工的微觀(guān)質(zhì)量是指加工外貌極小間距微小峰谷不屈度，即外貌粗糙度。外貌微觀(guān)質(zhì)量好，耐磨損，平板利用壽命高。而事情面小范疇內的局部畸變是指加工外貌不屈整、有變形。這里所說(shuō)的事情面小范疇，對小平板而言是局部位置，對大平板則是局部面積。
Error evaluation conditions for cast iron
plates and cast iron platforms
1. The principle of minimum condition uses
two parallel ambition planes to cover the actual appearance and minimize the
interval between the two ambition planes. The minimum interval is the flatness
deviation value.
2, the principle of affixing is tangent to
the reality of the ambition plane, and the maximum interval between the actual
appearance and the actual appearance is the minimum, the interval is the
flatness value
3. The principle of least squares places
the ambition plane in the middle of the actual appearance according to the
trend of the actual appearance, and minimizes the sum of the squares of the
points on the realistic appearance to the ambition plane, with the central plane
of the least squares as The base surface is evaluated, and the difference
between the maximum value and the minimum value of the plane deviation of each
measurement point is the deviation value of the measured appearance flatness.
4. The principle of the diagonal of the
cast iron platform is to evaluate the base plane by a diagonal line passing
through the diagonal of the measured appearance parallel to the other diagonal
line. The difference between the maximum and minimum valuesof the plane deviation of each measuring point is Measuring surface
flatness deviation value.
5. The principle of the loop method uses
the adjustment principle of measuring the closed loop, so that the interval
from the new position after the measurement of the measured points to the
measuring base becomes the interval of each point relative to the paying plane.
At this time, the ambition plane is the natural degree of the origin.
6. The principle of three-point method
delimits the ambition plane from the plane formed by the three points which are
farthest apart from each other on the real appearance and not on a straight
line, and the difference between the maximum value and the minimum value of
each measurement point from the plane deviation is The flatness deviation value
of the measured appearance.
7. The principle of maximum straightness is
the deviation of the maximum straightness of any section of the actual
appearance as the deviation of the flatness.
Local deviation of cast iron plate and cast
iron platform
The local deviation of the cast iron plate
(cast iron platform) refers to the local flatness processing quality of the
flat surface, including the microscopic quality of the surface processing and
the local distortion in the small surface of the surface. The so-called
microscopic quality of processing refers to the extremely small spacing of the
processing appearance, the small peaks and valleys, the roughness, that is, the
appearance roughness. The appearance is microscopically good, wear-resistant,
and the life of the flat plate is high. The local distortion in the small
category of the object refers to the unfinished and deformed appearance of the
processing. The small area mentioned here is a local position for a small flat
plate and a partial area for a large flat plate.
