Description

When in the use of EDM, use of kerosene as dielectric fluid is very common. However, from the point of safety, kerosene has many problems since it can cause a fire. Some studies were reported on EDM with nonflammable dielectric fluid. EDM with nonflammable dielectric fluid has an advantage over EDM with kerosene that it is free from fire and its rough-machining speed is faster. On the other hand, it has drawback that its finishing machining is not satisfactory.<br>In this report, authors aim to improve the efficiency of the EDM with nonflammable dielectric fluid. Authors have found that the tar which is made in EDM process is responsible for the bad quality of finished surface. Because it is electrified, the tar adheres to the surface of the workpiece in EDM process. The adhering tar disturbs the machining stability, and degenerates the quality of EDMed surface.<br>In order to improve the machining capacity, authors develop a new machining circuit. With this machining circuit, the voltage between the electrode and the workpiece is kept about 0V, and the electrified tar does not adhere to the workpiece. The performance of finishing-machining is greatly improved.
