Cutting Force and Temperature Analysis of Incone1690 Nickel-Base Alloy Under CMQL and UEV
Low temperature micro-lubrication(CMQL)can achieve better cutting friction performance,improve tool wear resis-tance and obtain better wear reduction effect.Ultrasonic elliptic vibration(UEV)can improve the machinability of difficult-to-work alloys.On the basis of ultrasonic elliptic vibration,low temperature micro-lubrication conditions were set,and the cutting effect was analyzed by experiments The results show that when UEV and CCMQL modes are adopted,the reduction ratio of cut-ting force and feeding force is 62.3%and 75.0%respectively,which can realize lower temperature control effect in the process of low temperature micro-lubrication,and effectively prevent the thermal softening problem of workpiece.Common cutting tempera-ture is close to445℃.Lower temperature can be obtained by UEV.At the same time,the temperature decreases by 16.1%when us-ing UEVand CMQL,while the temperature decreases by 19.5%when using UEVand CCMQL.By reducing the Angle of the noz-zle,lower cutting fog drop temperature is obtained,and the stress of the tool tip is reduced to realize tool protection and promote the extension of tool life.The research is helpful to improve alloy cutting technology and provides a way to improve cutting quality.
