aerometer Measurement of workpiece size accuracy error, the reasons may be in the following points:
    First, detect the environmental change of the workpiece.The gas gauge also has certain requirements for detecting the specific physical form of the workpiece. If the surface of the workpiece itself is the kind of rough result, then once processed there will be more obvious traces, so these wood chips or other oil traces will cause data deviation. In addition, during the use of the instrument, we should pay attention to the impact of the coolant, if there is dust or other impurities, then it is likely to cause accuracy errors, we should try to avoid these cleaning problems in the work.
    2. Excessive vibration.Because the air momentum meter will inevitably appear in the measurement process of vibration, but a small amplitude of vibration is actually acceptable, but if there are many other large equipment in the measurement environment, such as punching machines, or air compressors and other heavy equipment, then it is easy to affect the measurement. We should pay attention to the difference between the vibration of the mechanical equipment itself and the vibration caused by other substances in the outside world, the two kinds of vibration are not the same, and it is certain that the accuracy will also be affected in the later period.

    Three, compressed air.Because many tests require compressed air to be followed by coordinate measurement, such measurement has a certain impact on compressed air. In the measurement, water and oil substances should be prevented, which is easy to cause gas loss and also easy to cause bad results on the measurement track.
