Data Processing of Flatness Error Measurement Based on MATLAB

The principles of a new in-process measurement and control system for flatness errors in machining have been introduced. The laser-based system consists of a stylus, a geometrical table measurement system, and a forecasting compensatory controller. Through the application of the proposed system to simulated and actual cutting data it has been shown that improvements of flatness on the order of 80 percent are feasible.

A new flatness error measurement method was proposed for large quantities of E-type AC relay, which was consisted of three discontinuous plane. The research object of this thesis is on both sides of the work piece plane. The relay was measured by utilizing multiple laser displacement sensors, and used the development of PC software to extract the measurement key points and process the collected data, which was used the method of least squares to calculate more accurate flatness error value. This method can achieve substandard work-piece fast sorting and rapid online measure.

Measurement of parallelism error is one of important icon in the measurement of orientation tolerances. This paper presents new method of parallelism error measurement and is based on the flatness plane using minimum zone technique. Real coded genetic algorithm has been proposed to determine the flatness plane coefficients and flatness error. Flatness plane has been developed using plane coefficients and then parallelism error has been determined from the flatness plane. One example has been presented to show the effectiveness of the proposed parallelism error measurement method. The result of the proposed method has been compared to co-ordinate measuring machine (CMM) built-in function for parallelism error measurement and the results are in good agreement. In addition to determination of parallelism error measurement, the proposed algorithms also calculate flatness error and can also be extended to measurement of other types of geometrical tolerances with slight modifications.

Evaluation Parameters

The theoretical and experimental studies of statistical evaluation method for flatness error are conducted thoroughly, and evaluation parameters and corresponding practicable data processing model are provided. Furthermore, a large number of experiments have been done and statistical analysis has been conducted. The results show that the distribution of extract elements of almost 90 percent of the measured planes is accordant with censored normal distribution, which proves that statistical flatness error obeys normal distribution. The characteristic that sample points are random variables is taken full advantage of in the statistic method, and the flatness error can be calculated without the influence of gross error and therefore the rate of waste parts can be reduced effectively.
