negative rake angle

基本解釋

This error has influenced the precision of gear, especially, when negative rake angle of gear-shaped cutter is used, the current design method has not reguired the profile precision.
這種誤差影響了齒形精度，特別是負前角插齒刀，現(xiàn)行的設計方法不能滿足齒形精度。
The maximum stress point moves to compressive stress, depended on the experimental data, when negative rake angle substituted for positive one and other cutting conditions kept fixed.

This paper also discusses bit parameter design to improve the economy of PDC bits, such as negative rake angle and side rotation angle.
本文還介紹了為提高復合片鉆頭經(jīng)濟指標的鉆頭參數(shù)設計問題，如負前角，側旋角等。
