摘要
为了探究不同加工轨迹及其排布对工件磨抛加工表面质量的影响,本文进行了机器人磨抛轨迹对工件表面质量影响规律的研究。基于Preston去除方程和Hertz接触理论建立了砂带磨抛加工材料去除深度模型,分析了表面残留纹理的生成机理。以曲面航空发动机叶片为试验样件,利用自行搭建的机器人磨抛系统,分别使用等距轨迹、摆线轨迹进行加工试验,分析材料去除效果及表面纹理情况。试验结果表明,采用传统直线加工的等距轨迹于搭接处产生条带状纹理;摆线因其多方向性的加工动作,均化了表面纹理,提高了加工表面一致性。
In order to explore the influence of different machining paths and their arrangement on workpiece grinding effect,the influence law of robotic grinding paths on workpiece surface quality was studied.Based on Preston removal equation and Hertz contact theory,the material removal depth model of abrasive belt grinding was established.Then the formation mechanism of surface residual texture was analyzed.Taking curved aero-engine blades as experimental objects,equidistant paths and cycloidal paths were used respectively for machining experiments on a self-built robotic grinding system.Material removal effect and surface texture were analyzed.The experimental results show that the traditional linear machining isometric path produces strip texture at the joint.Because of its multi-directional machining action,the cycloid homogenizes the surface texture and improves the consistency of machining surface.
