Meet the minimum conditions to determine the value of the computer optimization of the flatness Value + (., Yi, z) {b. This Ⅳ points calculated the average of the vertical axis S = 1/NZ. ; C.

Asked by point to plane distance (which is to retain symbols) formula d - (AX + BY + CZ +1 )/(,tory burch shoes。+ B-C) t / fi = 1 ~ N, obtained by plane to the top of the points Tuen greatest distance plane (positive) and below the horizontal distance between the points to the greatest absolute value of dT (negative) value is at this time is the flatness of D-d a + dT 3 Z coordinates in the process of continuous change t find the minimum value of D. If the access point 3 of the step change Z coordinate value of fine enough, can seek to meet the operator sets the minimum value of the flatness conditions. Of course, the number of changes at this time the computer is running more than a relatively longer time to meet the minimum conditions 2, the flatness value of the computer even though the preferred running fast, but,stivali ugg, in the selected reference plane of the-A, the program has multiple cycles, And because many of the measured points, while taking into account the z coordinates of the possible range, so to minimize the number of t run the IBM PC but generally also need to run this program more than 1h. To reduce computer run time, so in the program the preferred method used to determine the way the plane is based on changes in a point Z, q is also continuous changes in the characteristics, as shown in Figure 2 where Figure 2, when the change to z, to obtain the minimum time value n Ⅲ m,ugg boots billig, at this time if a continuous increase in z. T will be increased when it is a D run to Z. , They no longer continue to change the point Z coordinates. Computer which can shorten the running time is too large flatness values measured 3 Example 3 shows the flat circle of 25 evenly spaced test points, the z coordinates given by the number in brackets is a unit tzm; If the Dayton Education leveling data using the diagonal method to process a manual to be more than 8h, the flatness is obtained 6.55gin and prepared by our software (I plant for sale) in the IBM machine running 20rain, then The results can be drawn. Well when the operator sets the minimum conditions for the flatness is 5.46m shows r use of computer processing speed, high precision. As a result, more accurately meet the minimum condition, is one kind of method should be promoted. 4 block diagram (Figure 4) \ ~ -/1ilZ. , Circle 2A. (N) A! ((, 6) H (a 【1_3A.
