MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202517043883 A) filed by Gleason-Pfauter Maschinenfabrik Gmbh, Ludwigsburg, Germany, on May 6, for 'method for toothing machining with subsequent chamfering.'
Inventor(s) include Brogni, Johannes; Kromer, Markus; and Schmezer, Ralf.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for toothing machining, in which, on a toothing machine controlled by a control device, a toothing system is produced or machined on a workpiece clamped on a workpiece spindle arranged at a first machine location by a toothing tool which is driven rotationally on a first tool spindle, and, in the same workpiece clamping operation or in a clamping operation of the machined toothed workpiece on a workpiece spindle arranged at a second machine location, a chamfer is subsequently produced on a tooth end edge of the tooth flank of the workpiece toothing system with synchronized rotation of the workpiece and a chamfering tool attached to the workpiece and driven rotationally by a second tool spindle, and with an advancing movement between the chamfering tool and the workpiece in a cutting manner with a cutting edge of the chamfering tool, wherein, during chamfering, the axial spacing between the rotational axes of the workpiece and the chamfering tool is not greater than half a spacing of the workpiece toothing system, the axis intersection angle between the tool rotational axis and the workpiece rotational axis and/or the axle intersection angle between the tool rotational axis and a surface perpendicular to that end surface of the workpiece which adjoins the machined tooth end differs from 90 by not more than 12, preferably not more than 8, in particular not more than 4, the predominant direction component of the advancing movement runs in the direction of the tool rotational axis, and, at any rate in its portion which forms the chamfer in the region of half a tooth height of the workpiece toothing system, the cutting edge has a greater direction component in the direction of the rotational axis of the chamfering tool than in the rotational plane which is orthogonal with respect to the latter."
The patent application was internationally filed on Nov. 06, 2023, under International application No.PCT/EP2023/080880.
