摘要可编程控制器是以电气控制和计算机技术为基础，以微处理器为核心，以工业自动化控制为目标，正在逐步发展的新型控制单元。它不仅能够取代继电器控制系统，而且能够使控制复杂的生产过程的工厂自动化网络得以实现。随着可编程逻辑控制(PLC)技术的发展，PLC 因其在工业领域的强大、易用、高可靠性、广泛适应性以及在自动控制过程工业中方便的过程扩展性能而变得越来越重要。它被越来越频繁地使用。可编程控制器将是工业控制的主要手段和未来最重要的基础设备之一。本次设计主要是利用 plc 对 ca6140 车床的电气部分进行改造，此次设计主要根据 i/o 点和性价比进行设计。首先要对设计有一个大概的概念，然后仔细分析车床的各种运动和车床电路图，接着分配i/o 并进行编程，最后进行仿真测试。改造后的车床要比以前使用方便。关键词：编程控制器 车床 电气控制IAbstractProgrammable controller is a new type of control unit based on electrical control and computer technology, with microprocessor as the core and industrial automation control as the goal, which is gradually developing. It can not only replace the relay control system, but also realize the factory automation network that controls the complex production process. With the development of programmable logic control (PLC) technology, PLC has become more and more important because of its strong, easy-to-use, high reliability, wide adaptability and convenient process expansion performance in the automatic control process industry. It is used more and more frequently. Programmable controllers will be the main means of industrial control and one of the most important basic equipments in the future.This design mainly uses plc to transform the electrical part of ca6140 lathe. This design is mainly based on i/o point and cost performance. First of all, we should have a general concept of the design, then carefully analyze various movements of the lathe and the circuit diagram of the lathe, then assign...
