Data Processing of Flatness Error Measurement Based on MATLAB

Flatness is an important parameter in evaluating the shape and position error of workpiece. Flatness error evaluation includes minimum area inclusion method, least square method, diagonal method, etc. The realization of measurement data processing by various methods is complex and has different accuracy. In this paper, various flatness error evaluation methods are analyzed. The GUI software of graphical user interface is established and its evaluation process is realized by using the software of MATLAB. The data processing program of MATLAB has the advantages of simple and reliable program, short processing time and greatly improved calculation accuracy. The simulation image can be obtained and the speed of data processing is greatly improved.
