Preventive measures to reduce the error of turning parts

- Nov 01, 2018 -

1. Measurement method. The measurement method refers to the combination of the measuring instruments and the measurement conditions used in the measurement. The measurement method should be based on the characteristics of the object to be measured to determine the best measurement method.


2, measurement accuracy. Measurement accuracy refers to the degree to which the measurement results are consistent with the true value. The accuracy of the RMS value of the measurement result is determined by the measurement accuracy.


3. Reduce the original error. Improve the geometric precision used in part processing, improve the accuracy of measuring tools, fixtures and tools themselves, control the force of the process system, deformation by heat, tool wear, deformation caused by internal stress, measurement error, etc., all directly reduce the original error.


4. Transfer the original error. The essence of this method is to shift the original error from the error-sensitive direction to the error-insensitive direction. Transfer the original error to a non-sensitive direction.


5, the original error of differentiation. In order to improve the processing accuracy of a batch of parts, it is possible to adopt a method of differentiating some original errors. For the surface of the part with high processing precision, it is also possible to adopt a method of gradually homogenizing the original error during the continuous trial cutting process.


6. Homogenize the original error. The process of continuously reducing and averaging the original error of the surface to be processed by processing. The principle of homogenization is to find out the differences between the closely related workpieces or tool surfaces by mutual comparison and inspection, and then perform mutual correction or reference processing.


7. Error compensation method. For some original errors of the process system, an error compensation method can be adopted to control its influence on the machining error of the part. This method artificially creates a new original error, which compensates or offsets the original error inherent in the original process system, and achieves the purpose of reducing machining errors and improving machining accuracy.


8. Error cancellation method. Use one of the original original errors to remove some or all of the original original error or another original error.
