A method for automatically repositioning a tool within the three-dimensional working space of a machine tool system from a current position to a target position, the method including the steps of:
(A) computing at least one retract move of the tool, based on a retract vector, from the current position to a retracted position in a retract plane by adjusting the retract vector, as necessary, such that the retract vector corresponds to movement of the tool toward the retract plane while remaining within the working space of the machine tool system;
(B) computing at least one plunge move of the tool, based on a motion vector that is an inverse of a plunge vector, from the target position to a plunge position in the retract plane by adjusting the motion vector, as necessary, such that the motion vector corresponds to movement of the tool toward the retract plane while remaining within the working space of the machine tool system; and
(C) moving the tool from the current position, to the retracted position and from the plunge position to the target position, wherein the retract plane defines a desired safe distance of the tool from a part prior to moving the tool from the plunge position to the target position.
