Flatness Measurement   Way Straightness Measurement

The straightness of a machine way can be measured with the laser using the incremental angle technique. The angle of a base at a series of overlapping positions are measured, these angles are then converted into height measurements. These height measurements can then be combined to give the total variation in straightness of the line or generator. When multiple lines or generators are measured the flatness of a surface (such as a surface table) can be measured.
