摘要/Abstract

摘要： 通过传统的编程方式(在线示教、离线编程)定义复杂曲面的抛光轨迹是一项复杂繁琐的工作,为了给机器人砂带抛光示教过程提供一种更加自然有效的交互方式,应用虚拟现实技术和力觉反馈技术,首先提出砂带抛光的力觉模型;然后,在此基础上,集成Phantom Desktop^力反馈设备开发了一套虚拟示教系统。用户在示教过程中能够更加自然真实地根据实时反馈力动态调整抛光力度、位姿等参数,获得理想的抛光质量。应用该系统进行的力学验证实验和工件加工表面质量评估实验表明:所提出的力觉模型能够准确模拟真实抛光过程中工件的受力情况,机器人在应用该虚拟示教系统进行示教后,所加工出的工件可获得与手工抛光相比拟的抛光质量。

Abstract: It is a complex and laborious job to define proper toolpath for belt grinding of complex part via traditional programming methods such as online robot teaching and Offline Programming(OLP).In order to provide a more natural and effective solution for robot teaching of belt grinding,a force feedback model for abrasive belt grinding is proposed by using virtual reality and haptic technology.Moreover,based the force model,a robot virtual teaching system is developed by integrating the Phantom Desktop^ force feedback device,which enable the user to adjust the grinding force,posture and other parameters dynamically in a more natural and real way to obtain a satisfactory grinding surface quality.Finally,the results of mechanical verification experiment and evaluation experiment of grinding surface quality show that the force model proposed is able to simulate the actual force accurately in belt grinding process,and moreover,after teaching process via virtual teaching system developed,the robot can obtain comparable surface grinding quality than the manual grinding via experienced work.
