MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202521101013 A) filed by Indian Institute Of Technology, Maharashtra, on Oct. 18, for 'a method for fabricating micro tools for biomedical and micromachining applications.'
Inventor(s) include Swarup Sunil Deshmukh; Mukesh Tak; Yogesh Dattatray Patil; Hrishikesh Pramod Jadhav; Rakesh Ganpat Mote; and Vinoth K B.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a method for fabricating a micro-tool for biomedical and micromachining applications using an electrochemical micromachining process. The present invention provides a non-contact machining method allowing the creation of micro-scale features, including uniformly and non-uniformly tapers with high accuracy, excellent surface finish, and minimal heat-induced material degradation. The method comprises providing an anode being a workpiece and a cathode being an insulated copper plate with a semicircular hole. The workpiece is positioned within a cathode aperture, maintaining an inter-electrode gap in a machining chamber filled with an electrolyte. While the electrolyte is circulated into a machining zone through a nozzle, the workpiece is simultaneously rotated and fed vertically, and a voltage is applied and controlled across the zones to achieve uniform material removal. The process results in a micro-scale tool with a controlled taper profile and high surface quality, suitable for dental and micromachining applications."
