  • Patent number: 12055915
    Abstract: This control system takes into account the thermomechanical aspects of materials to quickly and easily determine optimal cutting conditions and to automatically control machining to preserve the integrity of the workpiece. This system includes an acquisition module configured to acquire values of a set of input parameters relating to cutting conditions and material properties of the piece, and a microprocessor configured for determining at least one operating cutting parameter representative of a cutting signal from the machining apparatus using a set of output parameters of an integrity model previously constructed during a learning phase. The integrity model connects the set of input parameters to the set of output parameters comprising specific cutting coefficients representative of the material integrity of the piece, and establishes at least one fatigue threshold of the at least one cutting operating parameter. The fatigue threshold allows control of the progress of cutting operations.

  • Publication number: 20240201648
    Abstract: A validation method includes a series of steps of acquiring a set of input data with a set of operating parameters, carrying out a reference milling operation of a first master workpiece and measuring values of the machining forces which are applied by a milling tool, determining specific force coefficients representative of the machining forces, carrying out an orthogonal cut of a second master workpiece and measuring values of the geometric sizes, calculating a tertiary thermal flux generated during the orthogonal cut, calculating a final temperature from the tertiary thermal flux, and comparing the final temperature with a critical temperature to validate or reject the set of operating parameters, the method enabling a temperature criterion to be established in a simple, rapid and low-cost manner to validate or reject the set of operating parameters to ensure the material health of a workpiece to be machined while maximizing the productivity.
