How to determine the accuracy of the gantry image measuring instrument?
Technical parameter comparison:
First, it is necessary to verify the nominal accuracy of the instrument (such as the X/Y axis accuracy is usually (2.6+L/200) μ m, and the Z axis accuracy is (5.0+L/200) μ m)
1) And match it with actual application requirements. High precision models (such as the CHT series) can reach up to 1.8 μ m.
Actual measurement of standard parts:
Perform multiple measurements using standard parts of known size (such as gauge blocks) and compare the deviation between the measurement results and the actual values. For example, repeatedly measuring the diameter or height of the same workpiece and calculating the difference between the average value and the nominal value.
Repetitive testing:
Measure the same location multiple times (recommended ≥ 10 times) and observe the degree of data dispersion. The repeatability accuracy of the instrument should be ≤ 3 μ m, and the consistency of the results should be high.
