摘要
文中采用谐波分析的方法,分析各次谐波在一定测量精度条件下测点数对圆度误差的影响,并给出测量过程中测量精度、滤波条件与测点数的定量关系。为在圆度误差测量过程中合理选取测点数提供了理论依据,恰当地解决了测量精度与测量效率的矛盾。结论对圆弧误差及圆柱度误差的测量也有一定参考价值。
The article uses the method of harmonic analysis to study the effect of the measurement point number in circularity error,and provide quantitative relatio- nship between the measure precision, the condition of filter and the number of measurement point in the measuring process.
