Title: Wire-cut electric discharge machine
Inventor: SUZUKI TOSHIO
IPC: B23H7/04
Filed: 1986-11-05
Abstract: PURPOSE:To make the breaking of a wire electrode obviable without entailing any drop in an erosion rate, by detecting the continuous occurrence of discharge within the specified range, controlling a working condition, and making the feed of energy to an electrode gap so as to be reduced. CONSTITUTION:An arithmetic circuit 21 operates the absolute value of a difference between peak value of a peak value detector 19 of a discharge current and peak value in the last one time of a memory circuit 20 synchronously with a control circuit 14, comparing it with the setting reference value of a preset circuit 22, outputting the size to a count circuit 23. And, when the compared value is smaller than the reference value, count value of a counter is increased, but when it is larger than the reference value, the counter is reset. Next, when the count is increased and reached to the setting reference value of a circuit 24, there is a danger of disconnection so that a signal is fed to the control circuit 14, performing control over such a working condition as increasing downtime till impressing a voltage and so on, thus energy feed to an electrode gap is reduced. Since concentrated discharge before disconnection is interruptible and only the concentration time is controlled, an erosion rate is not almost dropped.
