在机械加工中,由于每一工序的误差影响因素很难用分析计算的方法确定某工序的加工精度,要确定加工精度,只能通过实际生产,用统计的方法加以整理和分析,这就是加工误差的统计分析法。统计分析法可以协助找出误差发生的原因,还可以以它为基础进行全面质最管理。但由于统计分析需要进行大量的数据处理,用手工计算很繁琐。因此,统计分析法在实际生产中的应用受到限制。利用微机辅助数据处理,就可以很快得到结果。效率高,准确。
In machining, due to the error factors of each process is difficult to determine the accuracy of a process by the method of analysis and calculation, to determine the machining accuracy, only through the actual production, statistical methods to be sorted and analyzed, this is the processing Statistical analysis of errors. Statistical analysis can help identify the cause of the error, but also can it be based on the overall quality management. However, due to statistical analysis requires a lot of data processing, manual calculation is cumbersome. Therefore, the application of statistical analysis in actual production is limited. The use of computer-aided data processing, you can get results quickly. High efficiency and accuracy.
