QCOS-对关键扭据操作的控制QCOS-Control of Critical Torque Operation 关键操作CRITICAL OPERATION如果某个操作被错误的执行会给车辆的安全因素造成非常有害的缺陷，那么这个操作被认为是关键操作 AN OPERATION IS CONSIDERED CRITICAL IF INCORRECT IMPLEMENTATION WOULD HAVE A DSIGNIFICANTLY DERTRIMENTAL EFFECT ON A SAFETY CHARACTERISTIC OF THE VEHICLE 焊接操作 Welding operations扭据操作 Torque operations加液操作（如刹车液） Fluid fillings(E.G…Brake Fluid)测试操作（如刹车测试）Testing operations(E.G…Brake Test)调整（如车轮定位） Adjustments(E.G…Wheel Alignment) QCOS QCOS=质量控制操作表是包括某一关键扭据操作的所有数据并在此操作的等级的基础上评价过程控制能力内容的文件是用以确保过程质量的工具QCOS=QUALITY CONTROL OPERATION SHEETIS A DOCUMENT CONTAINING ALL DATA RELATING TO ONE CRITICAL TORQUE OPERATION AND EVALUATES ITS PROCESSCONTROL ELEMENTS BASED ON THE RANKING OF THATPARTICULAR OPERATIONIT IS A TOOL DESIGNED TO ENSURE IN PROCESS QUALITY QCOS等级 QCOS RANKING 高重要操作 –点值＝12 直接与人类安全有关的HIGH IMPORTANT OPERATION-POINT VALUE=12 -DIRECTLY RELATED TO HUMAN SAFETY中等重要操作-点值＝9 非直接与人类安全有关的，可导致功能丧失或违反 政府法规MODERATE IMPORTANT IPERATION-POINT VALUE=9 -INDIRECTLY RELATED TO HUMAN SAFETY,FUNCTIONAL BRAKEDOWN CAN OCCURE OR CAN CAUSE VIOLATION OF  A GOVERNMENTAL REGULATION低重要操作-点值＝6 可导致用户强烈的抱怨LOW IMPORTANT OPERATION-POINT VALUE=6 -SERIOUS CUSTOMER COMLAINT CAN OCCURE QCOS控制方法 QCOS CONTROL RESOURCES 工具 自动检错 数据 记录 检查 (100%在线) 过程监控 过程控制 方法 制造 质保 过程责任 QCOS 控制资源表 QCOS CONTROL RESOURCES SHEET QCOS控制值计算QCOS CONTROL VALUE CACULATION QCOS控制方法 QCOS CONTROL RESOURCES 控制值计算公式:CONTROL VALUE FORMULA:控制值CONTROL VALUE= 实际总和ACHIEVED TOTAL 要求REQUIRED实际以QCOS控制资源表为参考 ACHIEVED KEEP CONTROL RESOURCES FOR REFERENCE 要求按QCOS等级确定(9点或12点) REQUIRED KEEP QCOS RANKING FOR REFERENCE QCOS控制值 QCOS CONTROL VALUE需=1 QCOS控制方法 QCOS CONTROL RESOURCES QCOS 工位的扭据控制QCOS STATION TORQUE CONT
