摘要： A device for machining a work piece creates an electrical potential between an electrode and the work piece or another conducting body proximate to the work piece. The electrical potential establishes an electrical field within the work piece that is expected to repel electrons and create a region of positively charged ions which repel one another. This region is expected to be weakened and material is expected to be removable from this region of the work piece using less force and energy than when machined by traditional machining techniques.

摘要： A system for removing one or more three-dimensional workpieces manufactured in additive manufacturing environment from a substrate plate is disclosed. The system includes an adjustable support tooling apparatus, a grinder, a cut-machining device, a work tank, a wire discharge machine and coolant pump filtration system. The adjustable support tooling apparatus is supporting a three-dimensional workpiece while it is being detached from a substrate plate by cutting device. The adjustable support apparatus of the present disclosure is also easily adaptable to various weights and geometric of workpiece. The improved substrate plate preparation machine in additive manufacturing enables to complete a job at one place, wherein the job is cutting the work piece and grinding the uneven cut surface of the substrate plate, thereby the ground substrate plate can be reused.

摘要： A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

摘要： A rotating electrode tool made of polycrystalline synthetic diamonds in a metal foundation is used in the electro-erosive machining and mechanical grinding of a metal bonded, electrically non-conductive hard material such as synthetic diamonds or boron nitrides in an electrically conductive metal matrix. The tool is first used to electro-erosively machine the workpiece. When a signal is obtained from the machining current or voltage indicating that no further electroerosive removal is possible, the tool automatically mechanically grinds the workpiece to remove nonconductive particles not removed by spark erosion.

摘要： An electroerosive contouring wire-cutting apparatus using a distilled or deionized water machining medium of a specific resistivity controlled to be in a range between 10.sup.2 and 10.sup.5 ohm-cm, and having abrasive particles of TiC, TiN, B.sub.4 C, BN, SiC, Al.sub.2 O.sub.3 and/or SiO.sub.2 of for example a particle size in the order of microns for delivery by the medium to the machining gap. A high-frequency vibration of a frequency of 1 kHz to 1 MHz is imparted to the wire electrode traveling through the workpiece in a direction transverse to the wire axis to enhance the combined electroerosive and abrasive actions at the machining gap. The machining medium is delivered by a nozzle, retrieved at a collector, and separated into its liquid and solid components in a separator. After deionizing the liquid and extracting the machining products, the abrasive particles and deionized water are mixed and recirculated through the nozzle.
