基于贝叶斯理论, 针对小批量、少样本的金柱腔生产过程, 讨论了生产质量控制模型的建立方法。利用大量历史数据和少量样本信息, 建立了金柱腔车削工序的质量控制模型, 并利用实际生产数据对该模型进行了验证。验证结果显示, 当前金柱腔车削工序的生产过程处于统计控制状态, 质量控制模型没有发出生产质量的虚警报, 建立的质量控制模型是有效的, 能够指导金柱腔车削工序的实际生产。

Turning procedure is one of the key production procedures in golden hohlraum. There are four key parameters of golden hohlraum including the diameter, the length, the rear and front laser entrances in the turning procedure whose stability and production quality determine the final quality of the golden hohlraum. It is necessary to strictly control the process of the turning procedure. In this paper, A Bayesian method for constructing production quality control model was discussed at the condition of small batch and sample. A production quality control model for turning procedure was established with large batch of history production data and small batch of current production data. The model was validated by one batch of production data. The results showed that the turning procedure was a stability production process. There was no quality alarm generated from the quality control model. It is believed that the quality control model is correct and able to supervise the actual golden hohlraum fabricating process.
