Flatness refers to the deviation of the height of a macro relief of a substrate from an ideal plane. The tolerance zone is the area between two parallel planes separated by the tolerance value. The flatness belongs to shape errors in shape and position errors.
The flatness measurement is performed by the following method:
1. feeler gauge measurement. The feeler gauge is mainly used for measuring the gap distance, and can only carry out rough measurement on the measurement of the planeness. Before the feeler is used, dirt and dust on the feeler and a workpiece must be cleaned. When in use, one or more pieces of the Chinese herbal medicine can be inserted into the gap in an overlapping way, so that the patient feels slightly dragging. The action is light when measuring, and hard insertion is not allowed. Due to the fact that the precision is low, the detection efficiency is low, the result is not comprehensive enough, and only the edge of the part can be detected.
2. Liquid level method. The level method uses a liquid level, which is constituted by a liquid level in a "communicating tank", as a measurement reference level, and then measures the liquid level with a sensor. Based on the working principle of the communicating vessels, the measuring device is suitable for measuring the flatness of continuous or discontinuous large planes, but has long measuring time and sensitivity to temperature, and is only suitable for planes with lower measuring precision.
3. And (5) performing a tabulation measurement method. The method is to put the measured part and the micrometer on the standard flat plate, and to measure the part point by point or along several straight lines by the micrometer along the actual surface with the standard flat plate as the measuring reference surface.
With respect to the related art among the above, the inventors consider that the following drawbacks exist: in the measuring process, multi-point measurement is needed, so that the influence of errors on the generation of a measuring result is reduced, workers need to measure the same point for multiple times or measure multiple points for multiple times, and the labor capacity of the workers is large.
