摘要:
针对学生使用的形位公差测量仪器原始误差大、测量精度不高等现状，提出一种基于MATLAB曲面拟合提高测量精度的方法，并给出了具体的数学模型。实验中采用前后对照的实验方法，对同一工件同一位置直线度误差测量，直线度误差值由原来的66.75 μm变成34.33 μm，精度提高48.6%。实践证明：此方法可以有效减小测量仪器原始误差，并且可以为其他测量仪器消除原始误差提供借鉴。
Abstract:
In order to solve large original error and low measurement accuracy of geometric tolerance measuring instruments used by students, one method of improving measurement accuracy based on MATLAB surface fitting was proposed; and a detailed mathematical model was established. The before and after comparison method was used in the experiment; for measuring straightness error on the same location of same workpiece, Straightness error value become 34.33 μm from the original 66.75 μm, accuracy is improved by 48.6%. Practice has proved that the original error of measuring instruments can be reduced effectively by this method; and it can provide a reference for other measuring instruments to reduce the original error.
