摘要
真空荧光屏（VFD）由于其工作电压低、体积小、亮度高，目前在计算机、家电、汽车、仪器仪表等领域都得到了广泛的应用。但是VFD生产厂家在实际生产中提出了印制电路板打孔精度不高的问题，需要提高数控打孔机精度。根据企业要求，本文提出了电路板打孔控制系统的工作原理及基于松下GT32触摸屏的系统人机界面设计。
本系统以松下PLC为控制器，松下触摸屏GT32作为人机界面，采用伺服驱动技术、变频器无级调速技术对伺服系统与变频器进行控制。文中对数控打孔机的软硬件结构设计进行了介绍，并从数控打孔机的功能入手，介绍了数控打孔机的各道工序，给出了具体的实现过程与实现步骤，进行一系列的实验调试，
系统运行情况证明该系统能保证数控打孔机工艺的一致性与稳定性，提高了产品质量；而且系统的硬件、软件成本低；而且本系统人机界面简洁易操作，抗干扰性强，便于操作，值得推广。

Abstract
Because of its low operating voltage, small size and high brightness, Vacuum Fluorescent Displayer (VFD) has been widely used in computers, home appliances, automotive, instrumentation and other fields at present. But VFD manufacturers forwards the problem of low PCB drilling precision, they need to improve the precision of CNC drilling machine in practical production. This paper mainly introduces the working principle of PCB drilling control system and the human-machine interface design that based on Panasonic GT32 touch screen.
Panasonic PLC to the system controller, Panasonic GT32 touch screen as a human-machine interface, the use of servo drive technology, frequency converter step less speed regulation technology of servo control system and inverter. In this paper, CNC drilling machine structure design of hardware and software are introduced, and from the CNC drilling machine function, introduced a CNC drilling machine for various processes, given the realization of the specific process and implementation of steps to commissioning a series of experiments. System operation to ensure that the system can process numerical control drilling machine consistency and stability, improved product quality; and the system hardware, software and low cost; and the system simple and easy to operate human-machine interface, and strong anti-jamming , easy to operate, it is worth promoting.

Keywords：CNC drilling machine、human-machine interface、PLC、touch screen
