Abstract
To prepare an essentially toroidal surface (7) on a workpiece (1) by machining, rotation of the workpiece around a first axis of rotation (3) and at the same time a rotation of the cutting tool (8) used for this machining around a second axis of rotation (10) are provided, wherein the second axis of rotation passes through the predetermined center (4) of the circular surface of the torus, which yields the surface (7) to be machined of the workpiece (7) during the rotation of the workpiece (1) around the first axis of rotation (3).
Claims9
A method of machining an essentially toroidal surface on a work piece where the toroidal surface is formed by rotation of a circular surface around a first axis along a radius of rotation, the circular surface having a circumference of about 270 degrees and a center where the radius of rotation is defined by (1) the center and (2) the first axis of rotation which is spaced from the center of the circular surface, the work piece arranged for rotation around the first axis while being in contact with a cutting tool at a circumferentially extending surface thereof, the method comprising the steps of:
- (a) rotating the circular surface around the first axis along the radius of rotation to obtain a toms of which the toroidal surface forms a portion;
- and
- (b) rotating the cutting tool without interruption through an angle of about 270 degrees around a second axis of rotation to form the essentially toroidal surface where the second axis of rotation extends at a right angle to the first axis and passes through the center of the circular surface.
