Study on Micromilling Assisted Electrochemical Composite Machining of Titanium Alloy
A titanium alloy micromilling assisted electrochemical composite machining method was proposed to address the issue of titanium alloys easy to passivate in NaNO3 electrolyte,leading to interruptions in electrochemical machining.Firstly,a micromilling assisted electrochemical composite machining tool was designed,and a mathematical model for the depth profile of composite machining was established.Then,the effects of feed rate,spindle speed and machining voltage on composite machining were studied through single factor experiment.The result indicated that among these parameters,the feed rate has the greatest impact on the depth of composite machining and material removal rate,while the spindle speed has the greatest impact on the localization of the contour.Under the parameter of feed rate of 3 mm/min,processing voltage of 24 V and spindle speed of 2000 r/min,the surface quality obtained is better and the experimental curve of machining depth profile is in great agreement with the mathematical model.
