4.3 for the chamfer:

after we check the original drawing from our customer, the chamfer on the polished side is not stated, but in 3D drawing on we can see the chamfer is 0.5mm,at last we get pieces which had the big chamfer and sent them to our customer. 对于倒角：

经核实从客户处收到的原本图纸，虽然我们从图纸中可以看到抛光面有倒角但未有尺寸标注，但从3D 图纸中可以得知倒角为0.5mm, 故我司将产品倒角做成0.5mm ，因此客户收到按此倒角要求生产的产品。完成时间 (When)

4.2 for the bigger dimension:

after we realize the tractability, we found one batch (31AM/031/14)of products produced in early September which exactly had the problem of bigger backside dimension due to wear and tear of die and we scrapped those pieces on 7th, September, and after

changed the mould in the dry press process, the problem was fixed. but for the products of 31AM/030&032/14, we double checked those pieces by random sampling method, according to the good result of samples those pieces were to normally proceed, they escaped to the customer. 对于后凸台尺寸过大：

在对产品实现可追溯性后，我们发现在9月初生产的一批(31AM/031/14)产品中确实存在因模具损耗而产生后凸台尺寸过大并于9月7日进行报废处理，但对于前后两批31AM/030/14及31AM/032/14由同一模具生产的产品我们采用抽样进行确认判定，抽样结果显示正常，故我司认为此为造成后凸台尺寸产品外流至客户处的原因。Explain with 5M1E method 鱼骨图解因法：
