在工業中,柱形螺絲梳刀被廣泛地採用來切削多头螺紋。確定螺絲軸向、法向斷面的截形是設計梳刀的重要問題。問題的分析指明:当工件螺紋在軸向断面的截形是直線時,螺絲梳刀时螺纹的截形在軸向及法向都是曲線的。当螺紋高度不大時,則可簡化,可用直線來代替曲線截形,此直線是在平均半径的圓柱和此截形的交叉點与截形相切;然而这必須考慮到螺絲梳刀螺紋的截形(軸向、法向)都
In industry, cylindrical screw combs are widely used to cut multiple threads. Determine the axial screw, the normal section of the truncated section is an important issue comb knife design. The analysis of the problem indicates that when the cross-section of the workpiece thread in the axial section is a straight line, the truncation of the thread in the thread combing is curvilinear in the axial and normal directions. When the height of the thread is not large, it can be simplified, and a straight line can be used instead of the curve truncation, which is tangent to the truncation at the intersection of the cylinder of average radius and this truncation; however, this must take into account the truncation of the thread combing thread Shape (axial, normal) are
