摘要
为了提高叶片磨削的加工质量和效率,将机器人和砂带磨削技术相结合,并应用到叶片加工领域中,介绍了该系统的特点和工作流程。比较了多种加工轨迹生成技术,确定采用等弦高误差法和等残留高度法,作为机器人磨削加工中步长和行距的计算方法。针对上述两种方法在叶片加工中存在的缺陷,对其做出了相应的改进;为了对改进后的算法进行评价,进行了手工磨抛和机器人磨抛两种加工方式的对比试验。研究结果表明,在粗糙度和表面一致性方面机器人加工明显优于手工加工,试验验证了机器人加工的可靠性和算法的有效性。
In order to improve the quality and efficiency of blade grinding,the robot and belt grinding technologies were applied to blade machining,and the characteristics and working process of the system were introduced.Through the comparison of multi-axial machining trajectory generation technologies,equal chord deviation fitting method and equal scallop height method were adopted to plan the robot trajectory.Because of their shortcomings in blade grinding,these two methods were improved.In order to evaluate the improved methods and compare effects of manual and robotic processing,a test was carried out.The experimental results show that,the blade machined by robot has much better surface quality than that by hand.The relevant experiment validates the effectiveness of robotic machining and the improved methods.
