两名不同的工人在钻这6台油箱，工人为了节省时间，只修磨了一套钻头，其中一名工人钻完甲板上4个18mm孔后等待另一名工人的22mm的钻头，在等待的阶段，他先用18mm的钻头预钻了孔，待后面一名工人用完钻头后再扩孔<br>但是接近午饭时间，午饭休息后工人忘记了这个事情，接过22mm的钻头就开始向后加工，导致此问题<br>检验人员没有全部核对每个孔的直径，导致此问题没有发现<br><br>之后我会培训操作人员和检验员，增强其自检意识，做完的产品自己应首先检查是否合格，再向下流转，同时要求检验员增加对直径尺寸接近的孔的检验比列<br>以防止该问题发生

Two different workers were drilling the six oil tanks. In order to save time, the workers only polished one set of drill bits. One worker finished drilling four 18mm holes on the deck and waited for the 22mm drill bit of the other worker. In the waiting stage, he pre drilled the hole with the 18mm drill bit and reamed the hole after the latter worker finished drilling the drill bit<br>However, it was close to lunch time. After lunch break, the workers forgot this matter and began to process backward after receiving the 22mm drill bit, resulting in this problem<br>The inspector did not check the diameter of each hole, so this problem was not found<br>After that, I will train operators and inspectors to enhance their self inspection awareness. The finished products should first check whether they are qualified, and then flow down. At the same time, I will ask inspectors to increase the inspection comparison of holes with similar diameter and size<br>To prevent this problem<br>

Two different workers are drilling these six oil tanks. In order to save time, the workers only grinded a set of drill bits. One worker waited for another worker's 22mm drill bit after drilling four 18mm holes on the deck. In the waiting stage, he first pre-drilled the hole with the 18mm drill bit, and then enlarged the hole after the latter worker used up the drill bit.But near lunch time, after lunch break, the workers forgot this matter, and began to process backwards after taking over the 22mm drill bit, which led to this problem.The inspector did not check the diameter of each hole completely, which led to the problem not being found.After that, I will train the operators and inspectors to enhance their awareness of self-inspection. The finished products should first check whether they are qualified, and then flow downwards. At the same time, I will ask the inspectors to increase the inspection ratio of holes with similar diameters and sizes.To prevent this problem from occurring.
