According to the current spinning processing industry’s evaluation standard for the processing process, it means that each process is evaluated according to the process flow. However, there is no unified evaluation standard for the entire spinning process. How to evaluate the spinning process Evaluation is still a difficult point, because the process is completed by multiple processes, which involve the mutual influence between different processes, which brings difficulty to the overall reliability evaluation of spinning processing.
The current spinning processing industry not only lacks indicators in the reliability judgment of the manufacturing process, but also has no way to judge the reliability of the complicated spinning process. At present, there is no set of forming theories that can be applied to the process to be reliable. According to the reliability requirements, it is necessary to analyze and test a large number of products obtained in the spinning process to determine the overall reliability based on these results. However, this work is a long-term and single process.
In the actual production process, in order to pursue economic benefits, many spinning processing manufacturers did not pay enough attention to such testing work. They started mass production without obtaining complete reliability test results, so that the reliability analysis of the process process It has lost the meaning of guaranteeing the quality of spinning products, so the development of an effective reliability determination method is the key to promoting the reliability of spinning process.
