摘要：轧制直柄麻花钻的几何参数影响钻头切削时的排屑和强度，而扇形轧辊的截形又决定了轧制直柄麻花钻的几何参数，因此扇形轧辊的截形参数直接影响钻头的切削性能。本文主要介绍了使用计算机辅助设计技术优化扇形轧辊截形参数的过程。

Abstract:The chip removal and strength of the twist drill are affected by the geometric parameters of the rolling straight shank twist drill during cutting，while the sectional shape of the fanshaped roller determines the geometric parameters of the straight shank twist drill，so the sectional parameters of the fanshaped roller directly affect the cutting performance of the twist drill.The computer aided design technology is introduced to optimize the section parameters of the fanshaped roller.
