| Abstract: | To solve the difficult problem of cutting engineering ceramics, the plasma arc cutting method with additional anode was offered. The rationale, forms and characteristics of the method were introduced. By means of cutting Al 2O 3 plates, the effect of each re-confined condition on plasma arc and kerf quality was studied. When the diameter of the nozzle is as 4mm and the kerf width is less than 5mm, the cutting speed may reach to 0 8~1m/min. The method is expected to become a useful technology for cutting engineering ceramics. |
| Keywords: | plasma arc cutting engineering ceramics additional anode plasma confinement |
