摘要:为解决四轴双铣刀机床无法让两把铣刀同时加工工件的问题,基于LabVIEW控制系统,采取工控机与运动控制卡,以及五台伺服电机,运用于双铣刀铣床控制系统中。开展双铣刀铣床加工机件的分析,建立组合机床五轴工作数学模型,计算出各轴间的运动关系,设计出五轴双铣刀铣床及其控制方法,在模拟仿真中对其机械设计上的可行性及生产加工效率进行分析及评价,并将此系统及机构设计运用于加工双排气塑料挤出机螺杆的实验。实验结果表明,五轴双铣刀数控铣床不仅可以同时独立分刀对该螺杆分段加工,而且在无故障前提下加工一根螺杆的完成时间由20 h缩减到10 h,操作简单。

Abstract:In order to solve the problems of the two milling cutters not working completely at the same time in the double cutter milling machine with four axises, based on LabVIEW control system, an IPC, a motion control card and five servo motors were applied to the control system of the machine. After the analysis of the double cutter milling machine processing, a mathematical model of five axis should be established while a motion relationship was figured out between shafts. A method was presented to design a double cutter milling machine with five axises and its control system. The feasibility of mechanical design and the production efficiency was analyzed and evaluated at the analog simulation of which was also applied to the experiment about processing a double exhaust plastic extruder screw. The results indicated that the five-axis CNC milling machine not only process a screw with two independent cutters by sections, but also made the achievement time be cut from 20 hours to 10 hours for each screw without faults, which was simple to use.
Key words:five-axis double cutter milling machine;LabVIEW;screw processing
