A New Grooving Method Based on Steady Wear Model in EDM.

Sensing and compensation of tool wear in milling EDM

“…When machining with a tubular electrode, such a continuous down-motion of the electrode, combined with the occurring tool wear, causes a rapid stabilisation of the electrode shape. This means that a steady-state shape of the tool tip is reached [2,14], which justifies 1D wear compensation. The down-motion is determined by off-line prediction of the decrease of tool length.…”
