- According to flatness error measurement of revolving body end-face, selection of sample points for flatness error measurement and flatness error evaluation method are mainly researched, the influencing factors are analyzed. Former concentric circular selection of sample points gets many restrictions, the measurement point arranges normally on the straight line that diffused. In this paper, a new concentric circular selection of sample points for flatness error measurement is presented and described by mathematical formulas in detail. The new method of arranging sample points can install quantity and the location of sample points wantonly on circumference direction and diameter direction, and satisfies the needs of the measure of flatness error. Based on using the research methods of relative subjects of other countries for reference, the simulation method for flatness error evaluation of concentric circular selection of sample points is presented, the mathematical model is simulated, and the simulation results are compared and analyzed. Since concentric circular selection of sample points is arranged the central symmetry of sample points, the orthogonal least-square mathematical models of flatness error evaluation for revolving body end-face are built, not only calculation is simple , and can raise the precision of calculation.
