ABSTRACT
Programmable controller (PLC) is widely used in nc machine tools and other industrial control. Part of CNC control can be divided into digital control and sequence control two parts.
摘要
可编程控制器 PLC 广泛应用于数控机床等工业控制中。数控机床的控制部分可分为数字 控制和顺序控制两部分。
本文描述了数控机床的基本组成、工作原理、分类及各自的特点。并且对数控机床中的 PLC 作了详细的介绍,把 PLC 在数控机床上的控制做了设计。然后以摇臂钻床 Z3040 为例, 描述了它的设计过程,包括控制系统电路的分析,Z3040 摇臂钻床原理图,用 PLC 编写程序 对机床进行控制。
This paper describes the basic CNC composition, working principle, classification and their respective characteristics. And the PLC for nc machine tools have also been introduced in detail, the PLC in the control nc machine design. Then Z3040 with radial drilling machine as an example, describes its design process, including control system circuit analysis, Z3040 radial drilling machine principle diagram, using PLC programming control of machine.
