How to Solve the Problem of Excessive Deviation of Measurement Results

When using the coordinate measuring machine for measurement, if the measurement deviation is too large, then please follow the following method to solve the problem.

Analysis of reasons for excessive deviation of measurement results of CMM:

1. The fixture is not reliable;
2. The workpiece surface roughness is too large or there is dirt attached to the workpiece surface;
3. The attachment connection of CMM is not reliable;
4. Calibration measuring stylus;
5. The measurement method is incorrect.

Coordinate measuring machine measurement results deviation is too large solution:

1. When measuring workpieces (especially small workpieces), make sure to use a fixture. The measurement results are relative to each other, which will help to improve the accuracy of the measurement.
2. The workpiece should be measured before constant temperature processing, and then carefully clean its surface to ensure that the surface is free of dirt.
3. Ensure that all accessories are connected reliably before measurement.
4. Before replacing the stylus, assemble and calibrate the stylus to ensure the reliability of the measurement results.
5. A reasonable and correct measurement scheme will effectively improve the measurement accuracy. Please confirm the rationality of the scheme before measurement.
6. Environmental conditions may cause measurement errors. Please measure in a correct environment.
