| Abstract: | Based on the least square principle of the evaluation of surface error, the one-order relations among the surface error, positioning errors of the tool with respect to the workpiece and the width error of the tool are studied on the surface's local structure. These relations present the error model of each error factor. The error of the model derived from one-order infinitesimal analysis is also studied. |
