通过对锯片侧角研磨机机械装置和工艺流程的研究设计了 PLC 核心控制系统、人机界面及两者间的通讯，控制系统的设计介绍了整个控制系统的硬件构造和电气连接系统的软件设计部分介绍了 PLC 关键程序和人机界面的设计文章的最后讨论了该控制系统的不足和改进方向，并对锯片侧角研磨机的前景作了展望关键词：硬质合金圆锯片；研磨机；PLC；人机界面ABSTRACTWith the increasing development of the woodworking, metal circular saw blade has been widely used, But the saw used to be grinded by professional, it. Is inefficient and low of the require precision. So saw blade grinding machine has been invented. It is a kind of machine which is used to grind the round saw blades. It is the typical product of the combination of mechanism and automation, representing the unique intellectualization of Chinese corporations. With the numerical control technology and adding the PLC which have control function to the machine, it can easily apply to the industrial process and also help the blades maintain a precise and sharp saw tooth. The point is that it can cut the waste of manual work and save more time, making the process much more efficiently.According to the angles grinded, the grinding can be categorized into three kinds: grinding the front angle, grinding the side angle and grinding the side angle. And from this, the machine can be classified into front angle grinding machine, side angle grinding machine and side angle grinding machine. This design project for graduation will focus on the side angle grinding machine.The essay will introduce the development of the round saw blade grinding machine home and abroad, analyse the working principle and technological process of the side angle grinding machine. It will design the core controlling system of the machine on the basis of studying the machinery device and technological process. After that, the essay will introduce the hardware structure and the software driving module of the whole controlling system.The essay discuss the defects of the design and the prospect of the side angle grinding machine in the end.Key words：metal circular saw blade；grinding machine；PLC；man-machine interface目 录1 绪论 ..............................................................11.1 数控技术的发展 .................................................11.1.1 数控技术的基本概念 .........................................11.1.2 数控技术的发展历史 .........................................21.1.4 我国数控技术历程和现状 ......................................41.2 锯齿研磨的现状 .................................................51.2.1 锯齿研磨的现状 .............................................51.2.2 锯齿研磨机的现状与发展前景 .................................51.3 研究内容和主要工作 .............................................52 硬质合金锯片刃磨技术和刃磨工艺流程分析 ............................72.1 硬质合金锯片刃磨技术 ...........................................72.2 锯片侧角研磨机工艺流程分析 .....................................72.2.1 总体功能概述 ...............................................72.2.2 设定功能 ...................................................92.2.3 手动功能 ...................................................92.2.4 自动功能 ..................................................103 锯片侧角研磨机硬件设计 ...........................................113.3 硬件部分总体分析、设计 .......................................113.2 控制核心 PLC 选型 .............................................113.2.1 选择 PLC 的理由 ...........................................113.2.2 控制点确定 ................................................133.2.3PLC 选型 ....................................................133.3 其它硬件的选型、设计 .........................................154 锯片侧角研磨机软件设计 ...........................................184.1 PLC 软件设计 ..................................................184.1.1 编程软件选型及介绍 ........................................184.1.2 关键工序程序设计 ..........................................194.2 人机界面软件设计 ..............................................234.2.1 软件选型及介绍 ............................................234.2.2 人机界面功能需求分析 ......................................244.2.3 人机界面详细设计 ..........................................245 锯片侧角研磨机控制系统总体调试 ...................................325.1 硬件部分调试 ..................................................325.2 软件部分调试 ..................................................325.2.1 PLC 程序调试 ..............................................325.2.2 人机界面调试 ..............................................336 总结 .............................................................356.1 系统总结 ......................................................356.2 发展前景 .....................................................35致谢 ................................................................36参考文献 ..............。
