摘　　要：为满足微小型复杂零部件的加工要求,设计构建出桌面型铣-3D打印复合数控机床的机械结构,采用"PC+Arduino"构架的开源式数控系统硬件体系,开发了低成本的控制系统,实现对此复合机床的运动控制。并针对铣削模块X坐标,对机床的重复定位精度进行检测与分析,挖掘误差产生的原因,为机床优化设计提供了相应的数据支撑及理论依据。In order to satisfy the manufacturing demand of minute-complex components,this paper designed a desktop milling-3 DP combined NC machine structure,and developed a low-cost control system based on the open-sourced numerical control system with＂PC＋Arduino＂structure,by which the motor control of the complex machine tool has been realized.Moreover,in this article,repeated positioning accuracy of the machine tool has been tested and analyzed on the X axis of the milling module.Hence,the reason that the errors generated has been found,which provides data support and practicable theory to the optimization of machine tools.
