Excellence in Motion Control Systems

An electrical discharge machine uses electrical current to erode the part being produced to the correct size and shape. The electrical eroding current generally comes from either a wire - wire edm, or from a pre-ground precisely profiled electrode - plunge edm. In both cases a control system is required to move the part or the electrode in the required direction while maintaining the gap between the wire or electrode and the part being produced. This is usually achieved by continuously monitoring the voltage between the electrode and the part.

The closer the two parts are, the lower the voltage. In reality one of the two components continually oscillates along the desired path at high speed, attempting to keep the voltage between the two constants. Essentially the better the control system the faster the oscillation, the more stable the voltage, and the faster the erosion process.

AMC motion controllers are used together with operator control panels implemented using WinAMC to control plunge electrical discharge machines. The high performance of AMC B motion controllers results in rapid oscillation and extremely precise voltage control, very consistent current flow and higher machine productivity.
