Application of Radius Error Compensation Principle in the Profile Measuring Instrument

摘要：

　　The paper analyses the compensation error which is caused by the probe radius of shape measurement instrument with the theory of envelope, and the model of the probe center is established.After having coordinates of envelope point corresponding to data point, actual curve equation has been obtained by using non-uniform B-spline curve.Finally, the effect is simulated and analysed by Matlab, and the result shows that the method of data processing has high precision.
