Manhart What are the factors affecting the measurement accuracy of a twisted axis CNC bending machine?

The factors affecting the measurement accuracy of a twisted axis CNC bending machine are multifaceted, mainly including the following aspects:
###1、 Equipment related factors
1. * * Equipment accuracy * *: The manufacturing accuracy, assembly accuracy, and fitting accuracy of each component of the torsion axis CNC bending machine itself will directly affect its measurement accuracy. The rationality of equipment structure design, material selection, and the advantages and disadvantages of manufacturing processes will all be reflected.
2. * * Equipment Stability * *: Equipment stability is also an important factor affecting measurement accuracy. If the equipment experiences vibration, looseness, or wear during operation, it can lead to measurement deviation.
###2、 Measure environmental factors
1. * * Temperature * *: Changes in temperature can affect the thermal expansion coefficient of the material, leading to changes in the size of the workpiece and subsequently affecting measurement accuracy. Therefore, the temperature of the measurement environment needs to be controlled within an appropriate range and maintained relatively stable.
2. * * Humidity * *: Excessive humidity may cause condensation on the surface of the equipment, affecting the performance of the measuring device; If the humidity is too low, static electricity may be generated, which can interfere with the measurement results. Therefore, it is necessary to control the humidity of the measurement environment within an appropriate range.
3. Vibration and Interference: External vibration and electromagnetic interference may have adverse effects on measuring equipment, leading to a decrease in measurement accuracy. Therefore, measures need to be taken to reduce the impact of vibration and interference.
###3、 Workpiece factors
1. * * Workpiece Material * *: The physical properties (such as elastic modulus, tensile strength, yield strength, etc.) and mechanical properties (such as plastic deformation ability, etc.) of different materials can affect the bending accuracy of the workpiece, indirectly affecting measurement accuracy.
2. * * Shape and Size of Workpiece * *: The complexity of the shape and size of the workpiece can also affect measurement accuracy. Complex shapes and sizes may require more precise measurement methods and equipment to ensure the accuracy of measurement results.
###4、 Human factors
1. Operator Skills: The operator’s skill level and familiarity with the equipment can also affect measurement accuracy. Skilled operators can more accurately set measurement parameters, operate measurement equipment, and judge measurement results.
2. * * Measurement methods and techniques * *: Different measurement methods and techniques may have different impacts on the measurement results. Therefore, it is necessary to choose appropriate measurement methods and techniques, and strictly follow the operating procedures for operation.
###5、 Other factors
1. Calibration and maintenance of measuring equipment: Measuring equipment needs to be calibrated and maintained regularly to ensure its measurement accuracy and stability. If the equipment is not calibrated and maintained in a timely manner, it may lead to deviations in measurement results.
2. * * Measurement programs and software * *: The quality and stability of measurement programs and software can also affect measurement accuracy. If there are errors in the program or software defects, it may lead to abnormal measurement results.
In summary, improving the measurement accuracy of twist axis CNC bending machines requires multiple aspects, including optimizing the equipment itself, improving the measurement environment, controlling workpiece factors, enhancing human operation level, and strengthening the calibration and maintenance of measurement equipment and programs.
