Optimization of High-Precision Machining Process of the Conical Product Based on the Six Sigma Method
In the face of the high quality,high efficiency and high benefit research and development needs of the new generation of aerospace products,the complex and high-precision assembly process is the key influencing factor re-stricting the batch delivery of products.In order to improve the assembly effi-ciency and quality of a conical space module,the key factors affecting assembly were determined through five stages of definition,measurement,analysis,im-provement and control based on the process optimization technology of six Sigma method,and the optimal process parameters were obtained through experimental de-sign and analysis.After the actual production application verification,the product assembly pass rate increased from 47.1%to 96.6%,which not only meets the design requirements of high-precision indicators of products,but also real-izes low-cost and high-efficiency product delivery,laying the foundation for mass production.
