基于DSP核心控制器的开放式五轴数控系统

为满足数控系统响应速度快、可靠性高、灵活性好等要求,构建了基于DSP核心控制器的开放式五轴数控系统.该系统由上位机、下位机和五轴数控机床等组成,上位机主要负责试样参数设置、硬件配置、图形实时显示、数据保存、报告打印等,通过高速接口与下位机通讯;下位机实时接收上位机命令,实时采集传感器数据返回给上位机显示,并做有关数据运算、伺服电机闭环控制等工作.测试结果表明,机床各轴运行流畅,满足加工要求.

Opening five axis CNC system based on core controller of DSP

In order to meet the requirements of the numerical control system such as fast res- porse, high realiability and good flexisility,the opening five axis CNC system based on core con- troller of DSP was developed. It consists of upper, lower machines and five-axis NC machine tools, etc. The upper computer is mainly responsible for the sample parameter settings,hardware configuration, graphical real-time display, data retention, report printing, etc. , and communi- cate with the lower machine through the highspeed interface, The lower machine receives real time commands from the upper computer, acquires and returns real-time sensor data to the upper computer display, performs the relevant data operation, servo motor closed-loop control,ect. Test results show that the axis machine tool ran smoothly and meet the processing repuirements.
