Abstract: Historical in-process machining information can be used to make machining process parameter recommendations. The disclosed systems and methods enable continuous learning for machining parameter selection using aggregated in-process machining information. The systems and methods save in-process machining data in a database using a standardized format, use data augmentation outlier detection, aggregation, and clustering algorithms to make machining process parameter recommendations and expected cut time predictions based on user inputs. The system can include a front-end dashboard to facilitate visualization and interpret results.

Abstract: A vibration absorber assembly which includes a cantilever beam component having a proximal end and a distal end, wherein the cantilever beam component extends along a longitudinal axis between the proximal end and the distal end. A distal support element supports the distal end of the cantilever beam component, and an absorber mass is movable in at least a radial direction with respect to the longitudinal axis. First and second support media support the absorber mass with respect to the cantilever beam component. The first support medium contacts the cantilever beam component at a first support region of the cantilever beam component, and the second support medium contacts the cantilever beam component at a second support region of the cantilever beam component, the first and second support regions being located at different longitudinal positions along the cantilever beam component. Other variants and embodiments are broadly contemplated herein.

Abstract: A cutting tool includes a cutting insert mounted to a head attached to a collar at a first end of the cutting tool. A shank is located at a second, opposite end of the cutting tool. A central cavity extends inwardly from the first end toward the shank. An eddy current vibration absorber assembly is disposed within the central cavity. The eddy current vibration absorber assembly includes an absorber mass made of an electrically conductive material, a magnetic material proximate the absorber mass, and a support member for supporting the absorber mass within the central cavity. The eddy current vibration absorber assembly is tuned by selectively adjusting a distance between the absorber mass and the magnetic material.

Abstract: A method for directly determining model parameters for a machining process that includes the steps of providing a system having a machining tool and a workpiece, and machining the workpiece using the machining tool, where the machining induces motions in the machining tool or the workpiece. The motions are then measured and used to estimate system characteristic multipliers (eigenvalues). A set of process model parameters is obtained by relating the eigenvalues to the results of an analytical method, a theoretical model or both.

Abstract: A high frequency flexure-based dynamometer (10) for measuring vibrations to use in determining cutting forces in a tool. The dynamometer device (10) may operate within a preselected high frequency range while measuring cutting forces less than about 1 N. The dynamometer (10) may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer (10) may include a workpiece (38) mounted to one of the two flexures (12) and a one or more precision accelerometers (30) mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.

Abstract: A method for predicting a tool point response of a spindle-holder-tool assembly to be used for high-speed machining applications is provided. The method includes determining direct and cross displacement-to-force receptances of a standard holder secured in the spindle based upon measurements of displacement-to-force taken at different rotating speeds of the spindle. The method also includes determining direct receptances at a free end of the standard holder based upon the determined direct and cross displacement-to-force receptances of the standard holder. Additionally, the method includes performing an inverse receptance coupling to simulate a decomposition of the standard holder into multiple subassemblies, the subassemblies including a spindle-holder base subassembly and an extended holder subassembly. The method further includes determining spindle-holder base subassembly receptances based upon the simulated decomposition of the standard holder.

Abstract: A client system issues a request for a resource over the Internet from a resource server. In constructing the response, the resource server includes: the data requested by the client, additional instructions for the client system to perform upon arrival of the response, and a natural language identifier which describes the resource requested by the client called the taxonomy string. Upon arrival of the response, the additional instructions inserted by the server system cause the client system to send a subsequent request over the Internet to an analytics system. The analytics request may contain a natural language description of the requested resource and a unique identifier to uniquely identify the client system. The analytics system performs analysis on the natural language identifier and stores it in a taxonomy database. The analytics system also performs calculations using the data provided in the analytics request to determine resource utilization patterns.
