Abstract：

Calculation formulas of blank diameter for common rotation drawing parts are complicated and not easy to remember.Especially using midine size often has decimal point,which results in complicated calculation.In view of the question,convenient calculation formulas of blank diameter were worked out when using midline size and not using it.At the same time,tolerance analysis was done.It proved that formulas are correct through some examples.
