基于一种改进逐点比较插补法的激光打标机控制加工算法

在激光打标系统中,逐点比较插补法是一种普遍使用的算法。这种算法在控制激光运动轨迹和对图像轨迹的拟合过程中,起到极其重要的作用。由于逐点比较插补法具有运算直观,脉冲输出均匀,调节方便等特点,所以是一种较为适合打标机系统应用的插补算法。但是传统的逐点比较插补算法存在精度低和速度慢等问题。为了改善该算法的性能,对传统逐点比较插补算法进行了改进,并进行了计算和模拟仿真。结果表明改进比较插补算法在精度和速度上都有明显提高。

Control machining algorithms of laser marking machine based on an improved point-by-point comparison method

Point-by-point comparison method is a commonly used algorithm in laser marking system.Interpolation plays an important role in controlling laser trajectory and fitting image trajectory.Because of its intuitive operation,uniform pulse output and convenient adjustment,point-by-point comparison method is a more suitable interpolation algorithm for marking machine system.But the traditional point-by-point interpolation algorithm has some problems,such as low accuracy and slow speed.In order to improve the performance of this algorithm,the traditional point-by-point comparison interpolation algorithm is improved,and the calculation and simulation are carried out.The results show that the precision and speed of the improved comparative interpolation algorithm are improved significantly.
