    摘要: A method for controlling flow localization in machining process is disclosed. By application of a constraint of sufficient level in the deformation zone and modifying the surface boundary conditions, suppression of unsteady flow and flow instabilities is achieved. The method enhances machined component quality by ensuring a uniform deformation state on the machined surface. Machined components are produced by ensuing uniform deformation by adopting constrained-cutting process for suppressing the instabilities and unsteady flow through a pre-determined location of the constraint of the constrained machining process relative to the machining tool.

    摘要: A cut optimization system controls chatter in a machine tool during a cutting operation. A microphone is configured to capture acoustic noise emitted by the machine tool during the cutting operation and to generate an AC signal corresponding to the captured acoustic noise. A filter is configured to attenuate frequencies of the AC signal outside of a frequency band and a rectifier is configured to rectify the filtered AC signal into a DC component. A controller is configured to compare the DC component with a threshold value and, if the DC component is greater than the threshold, cyclically vary the rotational speed of a spindle in the machine tool from a commanded speed.

    摘要: Machine tool systems and methods include methods of synchronizing cutting tools with a workpiece retainer. In some embodiments, the methods and systems provide at least two cutting tools that are synchronized to machine a common surface of a workpiece in a quick and efficient manner. A controller having a single line of code for controlling both cutting tools and the workpiece retainer may be used. The cutting tools may be synchronized such that they engage substantially opposite portions of the workpiece, thereby to reduce resulting forces in the workpiece that may tend to induce workpiece deflection and/or chatter. In other embodiments, a cutting tool is synchronized with a split workpiece holder that may be controlled to induce a compression, tension, or torsion pre-load in the workpiece.

    摘要: Portioning system (10) includes a conveyor (12) for conveying work products (14) past a scanner (16). A data processor (22) receives the scanning data and generates a thickness and/or volume distribution of the work product. The processor is programmed to determine in advance how the work product may be portioned into a plurality of desired end products, and more specifically how one or more of the end products may be cut and then subsequently sliced without having to re-scan the cut portion. The processor controls a cutting device (18) for portioning the work product under the cutting strategy determined by the processor, and also controls a slicing device (20) for subsequently slicing one or more of the cut portions to achieve a desired thickness per the determined cutting strategy.

    摘要: A portioning system (10) includes a scanner (16) for scanning a passing poultry breast (14). A cutting device (18), a slicing device (20) and/or other equipment may be used to portion, trim, or otherwise process the poultry breast under the control of a computer (22). The computer also utilizes the information from the scanner to determine position and the angular orientation of the poultry breast relative to a reference line by determining directional lines corresponding to physical attributes of the poultry breast. One directional line is related to the principal axis of the poultry breast, determined from the axis of least inertia of the poultry breast when analyzing the regions of the poultry breast above a selected elevation of the poultry breast.
