Abstract
A method is provided for the material-removing machining of fillets on a workpiece by means of a tool, more particularly a milling tool, which is guided over a fillet at a contact point. The invention is characterized in that the fillet is machined by means of a tool comprising a conical-convex cutting edge on a flank of the tool, wherein the tool, with the contact point on the conical-convex cutting edge, moves along at least one contact path running in the longitudinal direction of the fillet and the tool is inclined sideways in relation to the at least one contact path on the fillet such that a substantially sickle-shaped material engagement is formed in front of the contact point in the movement direction of the tool.
Claims21
A method for material-removing machining of fillets on a workpiece by means of a tool that is guided with a constant or varying contact point of the tool on a fillet, wherein the fillet comprises a juncture of two adjoining surfaces that define a corner having an angle therebetween such that the fillet connects the two adjoining surfaces of the workpiece with a round, tangentially adjoining transition on both sides of the fillet, the fillet being machined by means of the, wherein the tool has a conical-convex cutting edge contour on a flank of the tool, wherein the contact point of the tool is positioned on the conical-convex cutting edge contour on the flank of the tool, wherein the tool is moved with the contact point on a plurality of contact paths extending in a longitudinal direction of the fillet and is inclined sideways relative to the fillet, thus causing substantially sickle-shaped material engagement in the direction of movement of the tool in front of the contact point, the material engagement being formed between the contact point and at least one of a region of a lower end of the cutting edge contour or a region of an upper end of the cutting edge contour.
