Electrical discharge machine with tar build-up detector |
| 摘要 |
A method and apparatus for detecting the build up of tar on the electrode or workpiece in an electric discharge machine is achieved by determining the difference between a machining gap impedance found from dielectric fluid resistivity and an electrode area and a machining gap impedance actually measured.
