EDM (Electro-Discharge Machine) Process Monitor

Our customer produces precision parts for engine control systems. In this processing, multiple parts are machined in tandem through an EMD process.  If there is a problem with the anode or cathode, a defective component may be released to the customer.

We designed a process method, using high speed instrumentation, to monitor the EDM waveform. This instrumentation was added to the existing EDM control and PLC, with very little interuption to the operation.

 The main machine is monitored with a Red Lion HMI/gateway communicating to industrial computers running National Instruments Labview application.  When a fault occurs, the operator is alerted to a potential problem condition.  This prevents improperly machine components from passing through the system.
