| 摘要 |
An apparatus for measuring a surface of a workpiece is described. The apparatus comprises a support (7), attachable to the moveable arm of a machine (26), such as a coordinate positioning machine, and rotatable about first (1A) and second (2A) axes of rotation, the axes driven by first (M1) and second (M2) motors respectively. The apparatus additionally comprises a unidirectional probe or surface finish probe (4) for sensing the surface of a workpiece, rotatable about a third axis of rotation (4A). A rotation means (6) is provided for allowing rotation of the unidirectional probe or surface finish probe (4) with respect to the support (7) about a third axis of rotation (4A). |
