Patent number: 7277800Abstract: A system and method for monitoring freeplay within an actuator is provided. In accordance with various embodiments, the method includes collecting a plurality of actuator parameter data sets during a predetermined period. During the predetermined time period the actuator drive motor is commanded to extend and retract an actuator output ram operably connected to a movable component of a structural system such as a mobile platform. The method additionally includes selectively isolating various sets of the plurality of actuator parameter data sets that meet specific predetermined criterion. Furthermore, the method includes computing an amount of freeplay value within the actuator based on the isolated actuator parameter data sets.Type: GrantFiled: February 28, 2006Date of Patent: October 2, 2007Assignee: The Boeing CompanyInventors: James J. Sheahan, Jr., Jeffrey M. Roach, Kevin L. Swearingen

Patent number: 7272463Abstract: A method of determining a tool geometry and tool orientation for any prescribed path along a workpiece of a cutting tool is described. A parameter set is provided, where parameters of the parameter set include tool geometry and tool orientation relative to a surface of the workpiece. Values of the parameters in the parameter set are determined such that no local interference or global interference occurs, where local interference occurs when a portion of the tool immediately adjacent a cutting edge of the tool contacts a sidewall of a groove already cut by the cutting edge, and global interference occurs when a portion of the tool away from the cutting edge contacts a sidewall of a groove already cut by the cutting edge.Type: GrantFiled: May 24, 2005Date of Patent: September 18, 2007Assignee: General Electric CompanyInventors: Erwin Wenti Liang, Vinod Padmanabhan Kumar

Patent number: 7266420Abstract: The invention describes a method for the inspection of machining tools used in computational numerical control (CNC) machining centers. The invention will observe a machining tool immediately after use to determine if it has been damaged. The invention is based on a machine vision technology that uses one or more image sensors to acquire, locate and compare the tool to a good model. The inspection equipment is designed for implementation in the CNC automatic tool changing system and will alert the operator that tool has been damaged before the next operation. This immediate response of the invention will contain defect components and prevent damage to subsequent components. With the addition of an infrared image sensor the invention is capable of detecting worn or dull tools that may damage a component due to excessive heating.Type: GrantFiled: April 2, 2005Date of Patent: September 4, 2007Inventor: Gerald Walter Budd

Patent number: 7226337Abstract: Methods system and apparatus, including computer program products, for monitoring polishing a substrate. A polishing pad mounted on a platen is rotated at a first rotation rate, and a carrier head is rotated at a second rotation rate that is different from the first rotation rate. The carrier head carries a substrate and presses the substrate against the polishing pad. A sequence of data traces is acquired using a sensor mounted in the platen, wherein each data trace results from a separate scan with the sensor along a path across the substrate, and wherein the first and second rotation rates are such that a plurality of paths corresponding to a predetermined number of consecutive scans are substantially evenly radially distributed across the substrate.Type: GrantFiled: April 11, 2006Date of Patent: June 5, 2007Assignee: Applied Materials, Inc.Inventor: Jeffrey Drue David

Patent number: 7217071Abstract: In the method, a tool is tested for an aligning fit or an imbalance in a tool spindle. The tool spindle is set into rotation. A light beam is used to check whether the tool wobbles. The tool spindle and the light beam are moved relative to one another until the light beam impinges on the area covered by the wobbling movement and a received signal generated from the light beam has an intermittent signal path for the first time. The then prevailing relative position between the tool spindle and the light beam is evaluated in respect of a non-aligning fit of the tool or in respect of a tool imbalance.Type: GrantFiled: July 20, 2006Date of Patent: May 15, 2007Assignee: Cross Huller GmbHInventors: Thomas Bayha, Andreas Berger

Patent number: 7206657Abstract: A system and method are provided for real-time measurement of tool forces. A relationship between a motor characteristic and tool forces is determined by first directly measuring tool forces for a standard tool, work piece, and part program in a central facility. A force profile indicative of the tool forces and the standard tool, work piece, and part program are provided to a user at a user facility. The motor characteristic for a CNC machine at the user facility is then measured for the standard tool, work piece, and part program. Based on the force profile determined at the central facility, the relationship between the motor characteristic and tool forces is determined. Thereafter, the motor characteristic of the CNC machine is measured for a desired tool, work piece, and part program and converted to tool forces using the relationship between the motor characteristic and tool forces.Type: GrantFiled: January 7, 2005Date of Patent: April 17, 2007Assignee: Vulcan Craft LLCInventor: Donald M.
