【摘要】 进瓶螺杆的加工在机械加工中非常普遍，加工方法也有很多，通常使用数控车床配合宏程序加工。而大圆弧大螺距的螺杆使用数控车床有很大难度，一般使用四轴加工中心配合软件编程加工，因而加工成本较高。文章以典型的进瓶螺杆加工为例，通过对工艺流程、机床、工装、刀具和宏程序等5个方面对其加工进行优化改造，通过对不同工况条件下加工效率、设备成本、刀具消耗、加工质量和程序编写的优化，找出了保证加工质量的情况下经济效益较优的加工方法，实现了基于5参数自适应宏程序的进瓶螺杆类零件的低成本高效率数控加工，生产效率提高300%以上，加工成本降低了85%以上。更多还原

【Abstract】 The processing of bottle transporter screw is relatively common in mechanical processing, and there are many processing methods. CNC lathes are usually used to process these parts in conjunction with macro programs. It is difficult to use CNC lathes for screws with large arc and large pitch. Four-axis machining centers are used to process such screws with software programming, and the processing cost is higher. In this paper, the processing optimization of typical bottle transporter screw parts has been taken. The process has be optimized and reformed with five aspects: process flow, machine bed, tooling fixture, tool cutter and macro program. According to the research on processing efficiency, equipment cost, tool consumption, processing quality and programming under different working conditions, the processing method with better economic benefits which ensuring processing quality has been found.The low-cost and high-efficiency CNC machining of bottle transporter screw parts which based on 5-parameter adaptive macro program were realized. The production efficiency was improved by more than 300%, and the processing cost was reduced by more than 85%.更多还原
