Manhart How to avoid the occurrence of outliers in high-precision measurement of twisted axis CNC bending machines?

Avoiding the occurrence of outliers is the key to ensuring the accuracy and reliability of measurement results in high-precision measurement of twisted axis CNC bending machines. Here are some specific measures and methods that can help reduce or avoid the occurrence of outliers:
###1、 Ensure the accuracy of measuring equipment and tools
1. * * Equipment Calibration * *: Regularly calibrate the torsion axis CNC bending machine and its measuring tools (such as sensors, measuring tools, etc.) to ensure that their measurement accuracy meets the requirements. Calibration should be carried out by qualified professionals or institutions, and calibration records and certificates should be kept.
2. * * Equipment Maintenance * *: Strengthen the daily maintenance and upkeep of equipment, promptly identify and repair potential faults or wear and tear issues. For example, checking whether sensors are sensitive, whether mechanical components are loose or worn, etc.
###2、 Standardize operating procedures and standards
1. * * Develop operating procedures * *: Develop detailed operating procedures for the torsion axis CNC bending machine, specifying operating steps, precautions, and exception handling procedures. Ensure that operators strictly follow the procedures to reduce the impact of human factors on measurement results.
2. * * Training operators * *: Provide systematic training to operators to improve their operational skills, professional knowledge, and sense of responsibility. The training content should include equipment principles, operating methods, measurement skills, anomaly identification and handling, and other aspects.
###3、 Strengthen environmental control
1. Monitoring environmental factors: Monitor and control the measurement environment to ensure that environmental factors such as temperature, humidity, and vibration fluctuate within appropriate ranges. These factors may have a significant impact on the measurement results and must be strictly controlled.
2. * * Isolation of interference sources * *: Place the twisted axis CNC bending machine and its measuring equipment in a relatively isolated environment to avoid external electromagnetic interference, mechanical vibration, and other factors that may interfere with the measurement results.
###4、 Introduce quality control mechanism
1. Implement the first inspection system: Conduct a first inspection before each measurement, that is, use standard parts or samples with known accurate values for trial testing to verify the accuracy of measuring equipment and tools. If any abnormalities are found, the cause should be promptly identified and dealt with.
2. * * Use statistical methods * *: Use statistical methods to process and analyze measurement data, such as calculating statistical measures such as mean and standard deviation, to evaluate the stability and reliability of measurement results. Meanwhile, tools such as control charts can be used to monitor whether the measurement process is in a controlled state.
###5、 Pay attention to material properties and process parameters
1. * * Understand material properties * *: Familiarize oneself with the characteristics of the tested material, such as elastic modulus, yield strength, etc., in order to make reasonable adjustments and compensations during the measurement process.
2. * * Optimize process parameters * *: Based on the characteristics and processing requirements of the tested material, set the process parameters of the torsion axis CNC bending machine reasonably, such as bending angle, bending speed, bending force, etc. The optimization of these parameters helps to reduce measurement errors and the occurrence of outliers.
###6、 Record and trace
1. * * Recording measurement data * *: Detailed recording of data, time, environmental conditions, operators, and other information for each measurement, in order to facilitate subsequent analysis and traceability.
2. Establish an outlier handling mechanism: Once an outlier is detected, it should be promptly recorded and the outlier handling mechanism should be activated. This includes analyzing the causes of outliers, taking corresponding corrective measures, and verifying their effectiveness.
In summary, avoiding the occurrence of abnormal values in high-precision measurement of torsion axis CNC bending machines requires multiple aspects, including ensuring the accuracy of measuring equipment and tools, standardizing operating procedures and standards, strengthening environmental control, introducing quality control mechanisms, paying attention to material characteristics and process parameters, and recording and tracing. The implementation of these measures will help improve the accuracy and reliability of measurement results.
