Fig.10 Comparison of EDM efficiency with other tool materials (Cu electrode [-], ui=120V, SV=60V, iP=11A, te/to=0.5/5µs, t=10min) Axial vibration (large) No vibration C-PCD EC-PCD SKD61 WC C-PCD EC-PCD Comparison of the EDM Efficiency with Other Tool Materials The removal efficiency in the ultrasonic vibration assisted EDM of the PCD were compared with the values obtained in the discharge machining of die steel (SKD61) and tungsten carbide (RD50).
Though strict comparisons cannot be made as far as the same discharge conditions were used for all the workpiece materials, i.e.

In order to calculate the service life as precisely and reliably as possible we need good mathematical models for describing loading, geometry, properties of materials and fracture mechanics parameters.
The basic aim of the measurements was to obtain a correlation between the micro crack length and stresses and/or how to conclude from the stress what happen in the material, when the crack occurs.
Therefore, for calculations we have developed the gear stress intensity factor K which takes into account not only the stress of homogeneous material in critical cross section but also the stress concentration due to defects occurring there.
