Many users do not know the accuracy of their coordinate measuring machine (CMM) after using it for some time. How to control the precision of CMM in real time, this paper introduces some self-checking methods.
01.Use standard gauge to check the accuracy of the machine
The best way to check the accuracy of a machine is to use standard inspection tools. Measuring block, ring gauge, sphere, high precision square, etc. When the temperature changes or higher measurement accuracy is required, we can use the above standard tools to check the length, roundness, diameter and other parameters. When necessary, we can also make appropriate corrections. This is very useful for operators.
02.Check machine accuracy with typical parts
Standard workpieces are used to check the accuracy of the machine tool, but it is relatively complex and can only be carried out over a period of time. It is more convenient to use typical workpieces, complete automatic measurement procedures, and measure multiple rig calibrations. Then the calculation is carried out according to the statistical law, and the reasonable value and tolerance range are recorded.
03. Real-time monitoring
The CMM is monitored in real time by using sensors or monitoring devices to detect changes in its accuracy. This can be done by attaching sensors to key components of the measuring machine, or by using specialized monitoring equipment.
04. Data analysis
Collect and analyze the measurement data of the CMM on a regular basis to evaluate its accuracy. By building a database or using specific software to track measurement results, signs of declining accuracy can be detected in time.
05. Training and operating procedures
Ensure that operators receive professional training and strictly follow the operating procedures. Correct use and maintenance can ensure the accuracy of the measuring machine to the greatest extent.
