基于超声振动感知的智能自动化切削刀具的设计
Design of intelligent automatic cutting tool based on ultrasonic vibration perception
摘要
Abstract
To increase the stiffness level of automated cutting tools and extend the service life of tool components,an intelligent automated cutting tool design method based on ultrasonic vibration perception is proposed.Based on the structural parameters of the tool oscillator,determine the bending vibration mode and specific vibration frequency characteristics of the beam structure,and combine the excitation effect of ultrasonic elliptical vibration to complete the analysis of the vibration characteristics of the cutting tool.On this basis,using mechanical sensors,the structural composition of the sensing segment device is studied,and then the design of intelligent automated cutting tools is achieved through hinge flexibility modeling and processing.The experimental results show that under the principle of ultrasonic vibration perception,as the diameter of the center hole increases,the stiffness level of the designed cutting tool does show a continuous increasing trend,which is in line with the practical application requirements of extending the service life of tool components.关键词
