The use of the following quality-control instruments in the machining of cylindrical liners at repair shops is considered: Shewhart charts (of moving-range and individual-measurement types) and histograms for analysis of the adjustment precision. A monitoring checklist has been developed for determining the losses due to all defect types. Interchangeability among groups for piston–liner assemblies completely eliminates wasted inventory.

维修企业缸套加工质量控制

考虑在修理厂加工圆柱衬套时使用以下质量控制仪器：休哈特图（移动范围和单个测量类型）和直方图，用于分析调整精度。已经开发了一个监控清单，用于确定所有缺陷类型造成的损失。活塞-衬套组件组之间的互换性完全消除了库存浪费。
