| 中文摘要: |
| 介绍在普通数控车床上准确加工母线含非圆曲线的超声变幅杆的两种通用程序的编制方法及应用。方法一以等弦长划分待加工曲线决定节点,以平均曲率半径作为插补圆半径,以C语言编制出加工代码生成软件。方法二采用VB6编程,使用双圆弧法进行插补,伸缩步长法进行误差控制和决定节点,可设定并控制插补误差理论值,运行时生成的NC代码指令条数少,适应任何超声变幅杆的加工,界面友好易用。上述两程序在进行切削加工前,均可全程模拟加工过程。两软件经分别在GSK-928和G-CNC6135A(G)数控车床上应用,效果良好。而第一软件较完善。 |
| 英文摘要: |
| Two methods of designing hovel universal software for accurately machining the ultrasonic transformers with non-circular generatrices by common NC lathe ’were developed and presented. In the first method, the panel points were decided by taking equally chords of the circles, and the average radius was taken as the inserting compensation radius. C language was used to compile the software. In the second method the universal software is based on VB6. In the software, double-arc method was used toinsert compensation and flexible step method was used to decide the panel points from theoretical errors. The amount of created NC codes is small and inserting compensation theoretical errors can be set and controlled beforehand. It is suitable for machining any ultrasonic transformers, the interface of the universal software is friendly to users and easy to be used. In the two software, the dynamic imitation of the whole machining process and the forms of the finished products may be displayed on the computer screen before the transformer is machined. The two methods have been used efficiently at GSK-928 CNC and G-CNC6135A(G) lathes to machine separate the ultrasonic transformers. The second one has more advantages. |
