摘要: 三块平板对研法虽原理表述直观、便于操作,但缺乏理论分析,因此需要从理论上找到三块平板对研一定能获得高精度平面的原因。采用分形理论建立了平板三维模型,通过数学仿真方法模拟了三块平板对研的工艺过程。数据迭代计算揭示了三块平板对研后平面逐渐平整的内在机理。依据实验数据,通过点数和平面度误差评定验证了理论分析的正确性。

Abstract: The principle of three plates method was expressed intuitively and easy to operate, but lacked theoretical analysis. It was necessary to find the theoretically reasons for three flat plates always obtaining high-accuracy planes. Fractal theory was used to establish a 3D model for flat plates, and a mathematical simulation method was constructed to simulate of three-plate matching and scraping processes. Iteration and convergence analysis revealed the internal mechanism of the surface which was gradually flattened after the scraping. The correctness of the theoretical analysis was verified by point counts and flatness error evaluation based on experiments.

Key words: three-plate principle, high precision plane, mathematical simulation, fractal theory
