Experiments on High-Pressure Cooling Ultrasonic Vibration-Assisted Cutting Machining of Titanium Alloy
In order to optimise the machining performance of titanium alloy,a high-pressure cooling device is set to improve the cutting quality of titanium alloy.A suitable cutting parameter value interval is set,and it is compared with the conventional cutting method to judge the temperature and the degree of wear of the tool surface to change the situation.The results of the study show that when using ultrasonic vibration cutting mode,the tool will be separated from the workpiece,forming a higher pressure cutting fluid,optimising the flow and speed of coolant in the cutting zone to achieve a higher rate of heat transfer,causing a continuous reduction in the cutting temperature.Regularly distributed grooves were formed in the conventional cutting mode,while the ultrasonic vibratory cutting mode resulted in a periodically varying texture,with a large number of pits,bumps and some"ridges"observed.This study helps to improve the efficiency of high-pressure cooled ultrasonic vibration-assisted cutting and lays a theoretical foundation for the subsequent optimisation of machining parameters.
