Hi to you all,
We have a production line wit each operation performing a different operation to the product. The inspection process needs to involve, not only a check on their own work, but to validate the work from the previous operation. Does anyone have experience of this process and any pit falls or things to look out for. As I understand iot it will increase the opertunity of identifying an NCR by about 60% but I am not sure about that figure. I need to prepare a presentation on the implementation of this process so I need to research as much information as I can on the subject. Any information would help.
The number of activities involved in the operation depends upon your planning and line balancing. I believe you have production stages where each operator executes a series of activities. In our case we have defined the flow chart that typically has various processing stages and at defined crucial points we have introduced the quality checks. These checks are also online and involve various inspection activities.
We strive on inculcating the following golden rules :
An operator is the best inspector of his job.
An operator will not accept defective parts to his stage.
An operator will not deliver defective parts to his next stage.
Each stage activities in the flow chart is based on the typical knowledge, skill and expertise that is available. Every stage has marked bins to place defective assemblies or parts received. Such production line needs constant supervision and we have been hitting over 98% FPY (First Pass Yield) A drop in yield is mostly a new operator issue and very soon gets back into control.
