金属激光切割机焦点控制系统的设计

Design of Focus Control System for Mental Laser Cutting Machines

焦点控制系统是金属激光切割机至关重要的组成部分,它与激光焦点与工件之间距离的准确性和稳定性直接相关,由此决定了金属工件的切割质量和效率。为此,采用高性能DSP、高精度电容传感器等设计金属激光切割机焦点控制系统,对激光焦点与工件之间的距离进行实时精确的控制并配合机床运动控制卡完成整个金属激光切割流程。首先介绍了金属激光切割机焦点控制系统的结构和工作原理,然后重点介绍了系统硬件设计,同时给出了部分核心软件设计流程。

This paper introduces the structure and principle of focus control system designed tor mental laser cutting machines,and focuses on the hardware design and presents parts of the vital software process.Practice certifies that focus control system of mental laser cutting machines can work stably and reliably.
