Angle-rounding method and tool

A method of angle rounding at an intersection between two surfaces of a workpiece, the method comprising:

• machining away a minimum volume of material from an intersection of the two surfaces, thereby giving a convex rounded shape to the intersection of the two surfaces, the curved shape being located relative to the workpiece on an outside of a circular arc tangential to the two surfaces at a point where the curved shape connects with the two surfaces.

A milling, trimming tool for angle rounding at an intersection of two surfaces of a workpiece, the tool comprising:

• a body extending along an axis of rotation of the tool and including teeth regularly distributed about the axis and spaced apart from one another by flutes for receiving swarf,
• wherein each tooth includes at least one concave curved wall situated on an outside of a circular arc having its concave side facing towards the outside of the tool, and that is connected at its ends to ends of the concave curved wall.

A turning tool for angle rounding at the intersection of two surfaces of a workpiece, the tool comprising:

• a cutter plate including a concave curved cutting edge, wherein the concave curved cutting edge is situated relative to the workpiece for machining on an outside of a circular arc having its concave side facing towards the outside of the tool, and is connected at its ends to ends of the cutting edge.
