Abstract: Because of the disadvantages in evaluating spatial straightness error with traditional method, such as difficulty in solving the nonlinear simultaneous equation, the evaluating precision is lower and data processing can’t be automated. New method for evaluating arbitrary spatial straightness error is put forward. The particular data processing method and evaluating method are put forward, and the feasibility of method is validated by practical measurement. The result indicates that the method is simple and easy for automatic data processing by computer, and the evaluating precision is enhanced by 5% compared to the traditional method.

Key words: Evaluating method, Evaluating precision, Roundness error, Straightness error
