Patent number: 9687895Abstract: Processes by which bulk forms can be produced in a single continuous operation, as opposed to multi-stage deformation processes that involve a series of separate and discrete deformation operations or stages. Such processes generally entail deforming a solid body using a large-strain extrusion machining technique and deformation conditions that obtain a predetermined crystallographic texture in the continuous bulk form that differs from the crystallographic texture of the solid body.Type: GrantFiled: January 6, 2012Date of Patent: June 27, 2017Assignee: Purdue Research FoundationInventors: Srinivasan Chandrasekar, Kevin Trumble, Wilfredo Moscoso, Mert Efe, Dinakar Sagapuram, Christopher J. Saldana, James Bradley Mann, Walter Dale Compton

Patent number: 8694133Abstract: A method is provided for controlling a machining operation wherein a tool performs a machining operation on a workpiece. The method includes providing a tool holder for holding a tool, a workpiece holder for holding a work piece, and a linear slide for linearly moving a linearly moving part that is either the tool or the workpiece. The step of selecting appropriate machining parameters includes the step of selecting an appropriate feed rate for the linear slide move the linear moving part and appropriate rotational speed is selected for the rotator to rotate the rotating part. The set of appropriate machining parameters are incorporated into the digital controller. The digital controller is then used to control the operation of a linear slide, rotator and modulator to execute the machining of the workpiece by the tool in accordance with a selected appropriate set of parameters.Type: GrantFiled: September 4, 2010Date of Patent: April 8, 2014Assignee: M4 Sciences, LLCInventors: James B. Mann, Christopher J. Saldana, Wilfredo Moscoso

The method includes providing a tool holder for holding a tool, a workpiece holder for holding a work piece, and a linear slide for linearly moving a linearly moving part that is either the tool or the workpiece. A rotator is provided for rotating a rotating part that is either a tool or the work piece. A modulator is provided for modulating the movement of a modulated part that is either the tool or the workpiece. A digital controller is provided for controlling the machining of the workpiece by the tool. Appropriate machining parameters are selected for enabling the tool to perform a desired machining operation on the workpiece. The step of selecting appropriate machining parameters includes the step of selecting an appropriate feed rate for the linear slide move the linear moving part. An appropriate rotational speed is selected for the rotator to rotate the rotating part.Type: ApplicationFiled: September 4, 2010Publication date: March 17, 2011Inventors: James B.

Patent number: 7628099Abstract: A method of controllably producing chips with a desired shape and size. The method generally entails machining a body with a cutting tool while superimposing modulation on the cutting tool so as to move the cutting tool relative to the body being machined and cause instantaneous and periodic separation between the cutting tool and the body at a point of contact between the cutting tool and the body, wherein each separation between the cutting tool and the body yields a chip. In this manner, the shapes and sizes of the chips are determined at least in part by the modulation cycle, and particularly the length of time the cutting tool is engaged with the body being machined.Type: GrantFiled: May 3, 2006Date of Patent: December 8, 2009Assignee: Purdue Research FoundationInventors: James B.

Patent number: 7617750Abstract: A process by which nanostructured monolithic bodies can be produced in a single continuous operation, as opposed to multi-stage deformation processing. The process generally entails continuously producing a chip having a nanostructured microstructure by engaging a solid body with a cutting edge of a tool while the solid body and the cutting edge move relative to each other, and simultaneously extruding the chip in the immediate vicinity of the cutting edge, such as with a constraining member, as the chip is separated from the solid body by the cutting edge to continuously plastically deform the chip and produce a nanostructured monolithic body immediately downstream of the cutting edge. The shape and size of the chip can be simultaneously controlled by the extrusion process so that the nanostructured monolithic body has a predetermined geometry. The nanostructured monolithic body can be in the form of a product suitable for immediate use, or undergo further processing to yield a product.Type: GrantFiled: December 6, 2006Date of Patent: November 17, 2009Assignee: Purdue Research FoundationInventors: Wilfredo Moscoso, James B.

Publication number: 20060243107Abstract: A method for producing articles containing nanocrystalline microstructures, and particularly to a method of controllably producing nanocrystalline chips with a desired shape and size. The method generally entails machining a body with a cutting tool to produce polycrystalline chips having nanocrystalline microstructures while superimposing modulation on the cutting tool so as to move the cutting tool relative to the body being machined and cause instantaneous and periodic separation between the cutting tool and the body at a point of contact between the cutting tool and the body, wherein each separation between the cutting tool and the body yields a chip.
