[Abstract]:An axial layered cutting method for turning large pitch thread is presented. The key process control variables are revealed through the study of cutter contact relation and cutting layer parameters. The influence of screw spiral rising angle on the working front and back angle of left and right cutting edge and the influence of cutting order on cutting efficiency are discussed. Taking cutting efficiency, surface consistency of left and right thread surface as the design objective, taking tool geometry angle, cutting parameters and cutting sequence as design variables, the design method of axial stratified cutting process for large pitch thread is proposed. Two cutting tools were designed and grinded, and a matching process design scheme was put forward. The experimental results show that the process scheme obtained by this design method is compared with that obtained by turning large pitch thread cutting technology. It can obviously improve the pitch error, surface morphology and distribution of large pitch thread, and meet the requirement of machining quality of large pitch thread.

【正文快照】： 0引言螺距大于4 mm的螺纹定义为大螺距螺纹[1],它属于非标准件,牙型槽宽且深.此类大螺距螺纹常用于大型压力机调整组件的螺杆和螺母,以及自行火炮上的端口螺纹,并且在各个装备中起着重要的作用[2-4].因此,研究大螺距螺纹的切削方式,提出大螺距螺纹的工艺设计方法对保障和提高
