摘　　要：螺纹是机械零件常见的工艺特征,其加工精度和表面质量是影响螺纹性能的主要因素。以轴类零件的外螺纹和内螺纹为例,应用斯沃数控仿真软件,探究造成螺纹乱牙和导致螺纹加工扎刀的主要因素。结果表明:通过合理设置螺纹进刀段和降速段能有效避免螺纹乱牙现象,运用公式法生成螺纹加工各刀切削深度能在很大程度上消除扎刀造成的表面缺陷。Thread is a common process feature of mechanical parts,and the main factors affecting thread performance are machining accuracy and surface quality.This article takes the external and internal threads of shaft parts as examples,and analyzes the main factors that cause thread disorder and thread cutting with the help of Swansoft.The results show that by setting the thread feed section and deceleration section reasonably,the phenomenon of thread disorder can be effectively avoided,and the use of formula method to generate the cutting depth of each tool in thread processing can greatly eliminate surface defects caused by cutting.
