Abstract：

Causality of drawing rate surplus, distributive principle and calculating method are discussed. A calculating formula for determining the drawing rate in multiple-operation draw process is presented and the program is designed with the formula. This formula is simple and easy to determine the drawing rate of each operation. The calculating result meet the demands of technology design perfectly.
