摘要： Material is removed from a body of material, e.g. to create a bore hole, by plasma channel drilling. High voltage, high energy, rapid rise time electrical pulses are delivered many times per second to an electrode assembly in contact with the material body to generate therein elongate plasma channels which expand rapidly following electrical breakdown of the material causing the material to fracture and fragment.
