The efficiency of WEDM is affected by two factors. One is the current carrying capacity of the wire. The two is that the etching in the slit can not be removed in time. Its electrical conduction consumes pulse energy.

 

In view of the two main reasons that affect the machining efficiency of wire cutting, the following efforts should be made to improve the machining speed of EDM.

 

1., increase the energy of single pulse, that is, pulse amplitude and peak current. In order not to overload the current carrying capacity of molybdenum wire, the pulse interval should be enlarged correspondingly, so that the average value of current will not increase too much.

 

2. maintain the dielectric coefficient and insulation strength of the working fluid, maintain high spark explosive force and cleaning ability, and minimize the short circuit effect on the pulse.

 

3. improve the mechanical precision of wire cutting wire guide wire system, because the narrow seam always goes faster than the wide seam, and the straight seam always goes faster than the broken line seam.

 

4. increasing the wire speed properly, the water speed of the silk to the gap is quicker, the amount of water is increased, and the eroded material is more effectively discharged.

 

5. increase the enveloping of water in the gap, that is to let the water in the silk drive speed, the speed of the water to clean the clearance is strong.

 

6. improve the frequency tracking sensitivity and increase the utilization of pulse.

 

7. reduce the reversing time of the wire motor, start faster, and increase the effective processing time.

 

Through these efforts, improving cutting efficiency is effective, but it has limitations, because the way and control of high frequency power supply have not changed.
