| Abstract: | The minimum cylindrical envelope method (MCEM), a new method for spatial straightness error evaluation, is proposed. It is proved that the mathematical model for spatial straightness error evaluation is a nonlinear one and is not suitable for linearization. The criterion for the minimum condition and the method for spatial straightness error evaluation by computer are proposed. An example of error evaluation is given. |
