非接触式在机测量系统设计与应用
Design and Application of Non-Contact On-Machine Measurement System
摘要
Abstract
In order to improve the on-machine measurement efficiency in the milling process of complex curved surface parts,a non-contact on-machine measurement system based on line laser contour sensor is proposed.Firstly,the system composition,data communication mode and command coordination mode of the measurement system are designed according to the on-machine measurement requirements.Then,a mathematical model of sensor mounting pose calibration is established,and a non-contact calibration process is designed to realize the calibration of sensor mounting pose.Finally,based on the machining process of typical aircraft structural parts,the application of non-contact on-machine measurement is completed.The measurement experiment on the five-axis vertical machining center shows that the measurement error of the system is not more than±20 µm,and the experimental results verify the practicability and effectiveness of the on-machine measurement system.关键词
