Patent ID: 8257149

Claim:
A method of producing a rotationally symmetrical surface on a rotated workpiece wherein a cutting edge is brought into contact with the surface of the rotated workpiece, the method comprising: a) engaging the cutting edge with the rotating workpiece as the cutting edge is moved towards the workpiece in order to generate a new contour portion on the workpiece with the new contour portion having a width B, measured parallel to the surface; maintaining the cutting edge in the engaged position during at least one revolution of the workpiece; b) repositioning the cutting edge by means of the following sub-steps: b1) lifting the cutting edge from the workpiece as the cutting edge undergoing a movement generally perpendicularly away from the new contour portion; b2) advancing the cutting edge as the cutting edge undergoes a movement generally parallel to the new contour portion; wherein in step b) a maximum lifting path AW perpendicularly away from the new contour portion is smaller than the local oversize, LA, of the workpiece, wherein a total length of the displacement path VP of the cutting edge parallel to the new contour portion in steps a) and b) is smaller than or equal to the new contour width, B; and c) steps a) to b) repeated multiple times.
