Programmable current control system for wire electrode electrical discharge machining apparatus |
摘要 |
The system includes data input means for information relative to the material of the workpiece and the thickness of the workpiece. A read-only memory then provides information to a programmable counter so that off-time for the machining power pulses is appropriately provided for. In addition, there is manual preset means for setting the off-time to be provided during gap short circuit condition. An appropriate cut-off sensing circuit is operatively connected to the gap for sensing short circuit condition and initiating the pulse reduction but only for the duration of the gap short circuit condition.
