1. A method of contacting an object by an electrode with user-controlled parameters comprising:

  • (a) providing a movable electrode;

    (b) generating a speed control signal defining a rate of motion of the electrode;

    (c) generating a force control signal defining a force to be placed on the object by the electrode;

    (d) generating a position control signal defining a displacement of the electrode relative to the object;

    (e) generating a duration control signal defining a length of time the electrode contacts the object;

    (f) integrating the speed, force, position, and duration signals in a control means;

    (g) driving the electrode toward a position proximate the surface of the object by the control means at the rate of motion defined by the speed control signal; and

    thereafter(h) further driving the electrode toward the object at a rate of motion less than the rate of motion defined by the speed control signal.
