[0078] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0079] Such as figure 1 As shown, the quality control method of the present invention consists of two parts: First, establish an error transfer network model based on quality characteristics to determine the key characteristics that affect the quality of processing; then establish a Bayesian-VSSI control chart for the determined key characteristics to quality the processing process monitor.
[0080] Modeling of error transfer network based on quality features, such as figure 2 Shown.
[0081] The following is a detailed description of the error transfer network modeling flowchart based on quality characteristics.
[0082] 4.1.1 Error transfer network modeling based on processing features
[0083] Determine the feature of easy out-of-tolerance in the cylinder head processing process as the target feature (for example, build an error transfer network model based on q...
