using the real-time numeric control system as the controlling object, this dissertation designs the smallest network distributed manufacturing to test the ip multicasting and long-distance inspecting 实验表明:采用ip组播技术作为网络通讯的手段时,数据传输对网络带宽资源的占用不随目标节点的增多而成倍增加。
but it is designed by a new method and a new design thinking, as well as cpld is a new half-custom asic technology that will be used wider and wider . it is very significant to improve the numeric control system performance and enhance engineer design capacity 但作为设计控制系统的一种新方法和新思路,同时fpga作为一种半定制集成电路设计技术会越来越广泛地被应用,这对提高数字硬件系统设计水平和性能具有重要意义。
in order to improve the ability of aspheric optics manufacturing, a new cnc machine named asm is developed by ciomp, and its numeric control system is presents in this dissertation . the new machine has ability to fabricate off-axis " mirrors up to lm dimension, and the accuracy can reach up to 1 / 50xrms ( a . = 632.8nm ) 此外,文中还对新研制的六轴联动“asm数控非球面加工中心”的控制系统进行了介绍,并专门介绍了加工中心在线轮廓测量单元中测量误差的补偿模型,以及与加工中心配套的控制软件asm1.0的编制情况。
