Omni-directional computerized numerical control (CNC) machine tool and method of performing the same

A computer numerical control (CNC) machining apparatus, comprising:

• a first base having a top side, a bottom side, a width, and a length having a first end and an opposing second end, wherein said length spans along a Y-axis of a three-dimension (3D) Cartesian orthogonal coordinate system, wherein said three-dimension (3D) Cartesian orthogonal coordinate system further has an X-axis and a Z-axis;
• a second base vertically erected in said Z-axis and on said top side at said second end, wherein a longitudinal axis of said second base extends perpendicular to a longitudinal axis of said first base;
• a tool head support assembly that carries a tool head, wherein the tool head support assembly both pivots the tool head and linearly displaces the tool head;
• and
• a plurality of rotatable clamps, each of which is configured to independently hold, release, and move a workpiece along said Y-axis, and each of which is configured to independently rotate the workpiece 360° about said Y-axis,
• wherein each of the plurality of rotatable clamps comprises a respective four-directional square clamp that slides in or out in four directions so as to hold or to release said workpiece,
• wherein each four-directional square clamp comprises:
• two first arms for holding the workpiece, each of the two first arms having a respective longitudinal axis, wherein the longitudinal axis of one of the two first arms extends parallel to the longitudinal axis of another of the two first arms;
• two second arms for holding the workpiece, each of the two second arms having a respective longitudinal axis, wherein the longitudinal axis of one of the two second arms extends parallel to the longitudinal axis of another of the two second arms and further extends perpendicular to the respective longitudinal axis of each of the two first arms;
• a first bi-direction screw, a second bi-directional screw, a third bi-directional screw, and a fourth bi-directional screw,
• wherein the first bi-directional screw extends into and through each of the two second arms, and wherein the second bi-directional screw also extends into and through each of the two second arms and is oriented such that a longitudinal axis of the second bi-directional screw extends parallel to the longitudinal axis of the first bi-directional screw, and wherein rotation of the first and second bi-directional screws moves the two second arms toward and away from one another;
• wherein the third bi-directional screw extends into and through each of the two first arms, and wherein the fourth bi-directional screw also extends into and through each of the two first arms and is oriented such that a longitudinal axis of the fourth bi-directional screw extends parallel to the longitudinal axis of the third bi-directional screw, and wherein rotation of the third and fourth bi-directional screws moves the two first arms toward and away from one another.
