| Abstract: | The principle of three point method and its variation including two point method and four point method for roundness error separation was introduced. Moreover, the characteristics and measuring accuracy of these methods were discussed respectively. The weighting function has an important influence on measuring accuracy. Through reasonably choosing parameters of measurement system, harmonic suppression can be avoided. It was also pointed out that the proper method for roundness error separation can be chosen in different situations. |
