A machining system of complicated product is usually a serial-parallel multi-variation-source multi-stage manufacturing system, in which the final product variation is an accumulation or stack-up of variation from all machining stages. There are coupling relationships between variations from stages while different variations exist in a single stage. 复杂产品的加工系统往往是一个串行与并行相结合的多源多工序制造系统,最终产品质量受到制造过程中所有工序上多个偏差源的影响。
