| Abstract: | A mathematical model is developed to evaluate coaxial erroy by way of the least square method and the minimum zone method in the rectangular coordinates.The model is able to calculate the coaxial error with proper accuracy.The computing results indicate that the model developed is simple in programming.The model lays a theoritical foundation for developing a virtual instrument and system to measure form and position error. |
