【摘要】 主要介绍丝锥槽形的改进和加工不同金属材料时丝锥槽形的设计。尤其被加工材料是特种金属时,根据丝锥所适合的前角、刃瓣、心径以及所允许容屑槽大小,运用计算机辅助设计改进丝锥槽形,使得丝锥前角、槽底圆弧以及齿背角光滑连接,切屑成流线形卷屑。生产实践表明,该方法有效地规范了丝锥槽形的设计与制造,提高了产品质量。更多还原

【Abstract】 Mainly introduce the improvement of taps’trough shapes and the design of taps’ trough shapes in processing all kinds of metallic materials.Especially in processing of the special metallic materials.According as the adaption orthogonal、tool edge、bottom diameter and scraps’ groove of taps,using computer aid design the taps’ trough shapes of taps,in order to tangency of the orthogonal、scraps’ groove and tool edge’ back angle,making the scraps into streamline rolling scraps.Manufacturing practice shows that the method specification the desige and manufacture of taps’ trough shapes effectively,enhances the quality of products更多还原
