摘　　要：为了满足激光雕刻领域的实际需要,开发了一种基于PC和Windows操作系统打印机驱动架构的激光雕刻控制系统。该控制系统能够与多种图形、图像处理软件进行无缝连接,可以支持多种图形、图像文件格式。而且可以对图形、图像自动编程,使得用户能够像操作打印机一样操作激光雕刻机,方便了用户的使用。在此架构下,曲线轨迹被操作系统分解为连续的小线段,因此根据轮廓曲率变化对连续小线段衔接点速度进行了优化。并且对连续小线段进行插值生成三次样条曲线,从而得到光滑的曲线轨迹。实验结果表明该设计提高了进给速度,改善了机床的动态性能并且能够生成高质量的曲线轨迹。To satisfy the practical demand of laser marking machining,a laser marking control system based on PC and printer driver architecture of Windows OS is proposed.The control system is compatible with most of graphic processing software,through which it can support most of file formats.It can automatically program the image and the user can operate the machine as simply as a printer.Due to the architecture,the curve is broken into continuous short lines.Thus the feedrate of turning point is optimized based on curvature variation,and each small line is formulated into a cube spline to get a smooth contour.The experiment results show that both the efficiency and dynamic performance are improved and the high-quality contour is generated.
