Shot Surface Treatment Using Nondestructive Inspection Thresholds

The patent applies preliminary inspection before shot processing to evaluate whether treatment targets can achieve the desired effect. By conducting nondestructive inspection in advance and identifying targets that cannot achieve the desired effect, the system prevents unnecessary shot processing on unsuitable targets, thereby maintaining processing quality for viable targets while improving overall productivity by avoiding waste of time and resources on doomed targets.

The patent replaces destructive mechanical inspection methods with nondestructive inspection technology. This substitution enables accurate evaluation of treatment target states without physically damaging the targets, allowing for complete inspection of all targets rather than limited sampling. The nondestructive method maintains measurement precision while dramatically improving productivity by enabling total inspection of all treatment targets.

The patent applies local quality assessment by evaluating specific parameters of treatment targets individually rather than applying a blanket discard rule. The inspection system measures specific parameters and compares them against normal ranges, allowing for nuanced decision-making. Targets with parameters slightly outside the normal range but still within acceptable limits can be identified and processed with adjusted parameters, while only truly defective targets are discarded. This localized assessment maintains processing quality by focusing on actual defects while preserving productivity by salvaging marginally non-conforming targets.
