Method and apparatus for controlled-fracture machining

A machining apparatus for use in controlled fracturing of materials exhibiting both ductile and brittle properties comprising:

• a support mechanism extending from a base section;
• a turret connected to the support mechanism for providing substantially a rotational movement of the turret about the support mechanism;
• at least one cutting tool fixedly attached below the turret;
• at least one table attached to the base section for holding a respective workpiece in a fixed position in relation to the at least one table;
• and
• wherein the at least one cutting tool and the at least one table are controlled using a controller having a microprocessor for enabling independent movement in a three-dimensional workspace for cutting the workpiece into a predetermined shape using controlled fracturing such that the yield strength and the breaking strength of material in the workpiece are exceeded simultaneously such that there is instantaneous strain with no plastic deformation.
