注塑工藝參數(shù)全套

注塑工藝參數(shù)假如您有一間注塑廠，廠里有10個技術(shù)人員，個個牛氣沖天誰也不服誰，怎么判斷他們的工藝水平呢？取正常生產(chǎn)中的產(chǎn)品40模。找一個精度為三位數(shù)的電子秤。利用公式計算波動系數(shù)：CV=標準離差/均值根據(jù)波動系數(shù)就可以進行能力評價等級波動系數(shù)工藝評價10.01~0.1%精密成型20.1~0.32%質(zhì)量好，穩(wěn)定性高30.32~1%工藝較差，穩(wěn)定性一般4＞1%次品率高，不可接收波動系數(shù)的計算：注塑工藝波動系數(shù)序號#1#3#4序號#1#3#4重量（g）離差離差平方和重量（g）離差離差平方和199.55-0.2280.0522199.65-0.1280.016299.890.1120.0132299.790.0120.000399.54-0.2380.0572399.59-0.1880.035499.69-0.0880.0082499.890.1120.013599.980.2020.0412599.920.1420.020699.57-0.2080.0432699.68-0.0980.010799.62-0.1580.0252799.68-0.0980.01081000.2220.0492899.910.1320.017999.960.1820.0332999.940.1620.0261099.80.0220.0003099.820.0420.0021199.810.0320.0013199.850.0720.0051299.67-0.1080.0123299.57-0.2080.0431399.69-0.0880.0083399.880.1020.0101499.880.1020.0103499.920.1420.0201599.59-0.1880.0353599.890.1120.0131699.790.0120.0003699.840.0620.0041799.830.0520.0033799.930.1520.0231899.55-0.2280.0523899.59-0.1880.0351999.890.1120.0133999.59-0.1880.0352099.920.1420.0204099.960.1820.033平均值99.760.024平均值99.790.019#2平均值99.78#5方差0.021#7變異系數(shù)（%）0.146#6標準差0.145在#1紅色格子里面輸入40模產(chǎn)品重量。在#2格子里算出40個產(chǎn)品的平均重量。把每個產(chǎn)品的重量減去#2中的平均重量，得到#3的離差值。將#3的數(shù)據(jù)進行平方得到#4“離差平方和”。將“離差平方和”進行平均得到#5“方差”。將方差開根號得到“標準差”。再將“標準差”除于#2平均重量*100得到工藝的波動系數(shù)。拿著數(shù)據(jù)對照波動系數(shù)表就完成了。工藝牛不牛，數(shù)據(jù)說了算。等級波動系數(shù)工藝評價1
