摘    要：本文对GB2076-80中计算带37°30′倒角、75°主偏角、11°法后角正方形铣刀片m公称值的公式提出了修正。并就GB2081-80中规定的m值的偏差进行了探讨,论述了m偏差除受刀片周边d（或L）和a角的影响外,还受边长b,b_s′,刀片厚度S,90°角和K_γε角的影响。

Abstract: In this paper, the correction of the formula has been made for computing in GB2076-80 them normal value of the milling euttertip with 37°30′ chamferred corners, 75° cutting edge angle and 11° normal clearance. In addition, the m deflection given in GB2081-80 has been approached. It has been discussed that the m deflection is affected by the side-length b, b_s, thickness S of the tip, 90° angle and K_γε angle as well as by peripheral d （or L） and α angle.
