Research on Edge Quality Control Method of TC4 Titanium Alloy Wire EDM
In order to improve the edge quality of WEDM machining TC4 titanium alloy,com-bined with the characteristics of WEDM machining and orthogonal test,the four factors of pulse width,channel,tracking and wire speed were used to measure the edge quality defect of machining workpiece at different angles,and the main parameters affecting the workpiece defect at different cutting angles were studied.The optimal cutting parameters under the condition of minimum defect at each angle are ob-tained.The results show that when the pulse width is 9µs,the tracking value is 4,there are 5 channels,and the wire transport speed is 50m/min,the minimum angular defect area of TC4 titanium alloy is 0.032 mm2.When the pulse width is 32µs the tracking value is 2,the channel is 7,and the wire transport speed is 50 m/min,the fastest material cutting speed is 9.7 mm2/min.
