摘　　要：研究了采用CTP技术的凹印雕刻机的运动原理,通过对网线数和网穴角度等关键参数的计算分析,建立了可雕刻任意网穴角度的菱形网点的传动关联模型,设计出一种基于现场可编程门阵列(FPGA)的运动控制卡,并定制适合雕刻系统的多轴电机加减速算法,以保证高速及高精度控制的需要。最后,将该设计方案应用于8KHz的高速凹印制板电子雕刻机,实测雕刻结果的正确性验证了设计方案。The motional principle of gravure engraving machine using CTP Technology was studied.Through the calculation of key parameters of lines and cell＇s angle,three-axis transmission association model was established to engrave cells of diamond shape with any cell angle.Based on these studies,a motion control card is designed using Field-programmable gate array（FPGA）.To satisfy the requirements of high-speed and high-precision control,a rational motion control algorithm was proposed for motor＇s acceleration and deceleration.Finally,the system was applied to engrave printing gravure cylinders using high-speed（8 KHz）,and the experiments verified the design.
