前期通过对数控实训台需要满足技术要求的统计，确定基本的设计思路，再根据基本数据计算电机选型，根据需要满足的控制要求，确定控制方式是由PLC控制，根据PLC的特点和优势来整合编排需要控制的地址数量，设计好控制电路，同时也要满足学生对机器进行操作的方便和快捷，良好的人机界面设定也是相当有必要的，于是在经过大量的查阅以及经验，基本确定了PLC电路对系统的控制。
最后对复杂电路图的安排和设计，需要进行大量的资料文献查找和对比各种电路控制的优势和特点，最后进行设计和绘制

The graduation design topic FA - SV - TS - L plate type linear motor training machine electrical control system design, is based on the current university mechanical professional students of deep the understanding of the numerical control lathe, the lack of practical experience, the design of project. We the design of numerical control practice brings together the characteristics of nc machining, and some basic circuit fault characteristics. In the nc training course has not yet universal, the design results has a certain value. 源\$自,六.维/论[文;网'www.lwfree.cn
Prophase of numerical control practice need to meet the technical requirements, determine the basic design idea, according to the basic data to calculate motor selection, according to the need to meet the control requirements, determine the control mode is controlled by PLC, according to the characteristics of the PLC and advantage to integrate choreography need to control the number of addresses, good control circuit design, but also to meet the student to the machine to operate convenient and quick, good man-machine interface set is quite necessary, so after a lot of reference and experience, the basic circuit of the system determines the PLC control.
The arrangement and design of complex circuit diagram, a lot of information literature search and comparative advantages and characteristics of various circuit control, the final design and drawing
Keywords: linear motor, CNC system, training table, electrical control systems, circuit diagram, PLC,
