摘　　要：为保证火炮身管膛线数控自动加工过程的实时性,启动自动加工前,将用户选定的膛线加工数据按微直线进行粗插补,其结果按帧结构存放到主机扩展内存。动态过程中,只需从扩展内存中取数据即可。同时采用高速并行数据传递,及多级缓冲预读技术,以解决因主机在自动加工循环不确定周期过程中可能不及时分解数据的问题。To ensure the real-time in artillery rifle automation manufacturing, before starting, put the first interpolation result of the rifle selected by user into the extend memory in forms of frame. In dynamic process, only directly getting the data from extend memory is OK. Using high speed parallel bus to transmit data and adapting multiple levels buffers and pre-reading technology in order to resolve the problem that master CPU may not interpolate the data in time during the dynamic process.
