Abstract: 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.
