摘要
文章建立了A-B双转台五轴加工中心环形铣刀在端铣中3D刀具补偿模型,分析了奇异点对机床运动轴速度的影响和奇异点的判断依据以及优化方法;在VS2010环境下完成了针对加工文件优化处理软件的开发,利用软件对带有奇异点的加工文件进行优化,以电机跳动时产生的跟随误差作为标准在数控系统平台上进行测试,结果表明电机的跟随误差明显减小;将优化过的义齿加工文件在五轴加工平台上进行加工测试,结果表明加工表面过切点减少,表面质量得到提高。
The 3D tool compensation model of ring mill cutter of A-B double turntable five-axis machining cen- ter is set up. The influence of singular point on the machine axis speed is explained and the method of judg- ment and optimization is put forward. The development of optimization software for processing file is comple- ted in VS2010. Taking the follow error of motor as standard, the optimized processing file with singular point is tested on the NC system platform, and the result shows that the motor follow error decreases effectively. The optimized denture processing file is tested on five-axis machining center, and then more smooth surface with the reduction of the number of overcut point is gotten.
