| Abstract: |
| This article researches the measurement error which is caused by the misalignment of measuring needle contact measuring direction and normal direction of the contact surface. The relationship between the measurement error and the contact measuring direction is found out through a lot of experiments and the corresponding theoretical analysis. It provides theoretical basis for engineering survey personnel to reduce the measurement error and improve the measurement efficiency. |
| Key words: tri-ordinate measuring machine contact measuring direction measurement error |
