Patent number: 11540408Abstract: Methods and structures for forming anodization layers that protect and cosmetically enhance metal surfaces are described. In some embodiments, methods involve forming an anodization layer on an underlying metal that permits an underlying metal surface to be viewable. In some embodiments, methods involve forming a first anodization layer and an adjacent second anodization layer on an angled surface, the interface between the two anodization layers being regular and uniform. Described are photomasking techniques and tools for providing sharply defined corners on anodized and texturized patterns on metal surfaces. Also described are techniques and tools for providing anodizing resistant components in the manufacture of electronic devices.Type: GrantFiled: July 22, 2016Date of Patent: December 27, 2022Assignee: APPLE INC.Inventors: Lucy Elizabeth Browning, Charles B. Woodhull, Bryan Patrick Kiple, David A. Pakula, Tang Yew Tan, Julie Hanchak-Connors, John Murray Thornton, III, Thomas Johannessen, Peter Russell-Clarke, Masashige Tatebe, Napthaneal Y. Tan

Patent number: 9663869Abstract: A metal part is surface treated using anodization and plating processes to produce different finishes on selective regions of the metal part. The different finishes can contrast in decorative appearance (such as color, shininess and texture) and structural properties (such as wear resistance).Type: GrantFiled: August 17, 2012Date of Patent: May 30, 2017Assignee: Apple Inc.Inventors: Brian P. Demers, Napthaneal Y. Tan, John M. Thornton

Patent number: 9545024Abstract: The embodiments described herein relate to methods, systems, and structures for cutting a part to form a highly reflective and smooth surface thereon. In some embodiments, the part includes substantially horizontal and vertical surfaces with edges and corners. In described embodiments, a diamond cutter is used to cut a surface of the part during a milling operation where the diamond cutter contacts the part a number of times with each rotation of the spindle of a milling machine. The diamond cutter has a cutting edge and a land. The cutting edge cuts the surface of the part and the land burnishes the surface of the part to form a highly reflective and smooth surface. Thus, the diamond cutter cuts and burnishes portions of the part, thereby eliminating a subsequent polishing step.Type: GrantFiled: September 11, 2012Date of Patent: January 10, 2017Assignee: Apple Inc.Inventors: Napthaneal Y.

Patent number: 9138814Abstract: A method for machining may include providing a workpiece with a major (e.g., top) surface and an edge at a perimeter thereof. The method may also include providing a machining tool including an outer rotary cutter and an inner rotary cutter. The workpiece may be machined in a single pass of the machining tool around the perimeter thereof. Machining the workpiece may include simultaneously machining the edge with the inner rotary cutter and machining at least a portion of the major surface with the outer rotary cutter. Accordingly, the edge and at least a portion of the major surface of the workpiece may be simultaneously machined in a single pass. The inner rotary cutter may also simultaneously machine an undercut at the edge of the workpiece. A related machining apparatus including the machining tool is provided. Further, a computer readable medium may include program code for performing the above-described operations.Type: GrantFiled: July 5, 2012Date of Patent: September 22, 2015Assignee: Apple Inc.Inventors: Piotr S. Trzaskos, Donald Q. Ross, III, William S. Masek, Brian K. Copeland, John P. Ternus, Erik D. Gillow, Napthaneal Y. Tan
