In the small-batch production mode of multiple varieties of piezoelectric ceramics, according to the special requirements of batch sintering of the same batch of products in the sintering process, as well as the lack of quality sample data, quality status monitoring and inaccurate early warning, a combined process quality monitoring method of general control chart and CUSUM control chart was proposed. The method can effectively identify the slight deviation of quality and realize the early warning of process quality. The feasibility of this method is verified in this paper.
