Abstract:
1. A method for grinding elongated concavities previously roughed out in one side of a part, said concavity having a section perceptibly in the shape of a portion of circle in a plane perpendicular to a rotation axis of a grinding tool, wherein the method includes the following steps: positioning the grinding tool in a resting position, loading the part to grind, displacing the grinding tool relative to the part to grind along a parallel axis that is parallel to the tool's said rotation axis, displacing the grinding tool relative to the part to grind along a perpendicular axis that is perpendicular to the tool's rotation axis, so as to bring the tool in grinding start position, and grinding the concavity by combining rotation movements of the grinding tool and rotation movements of the part around said rotation axis and said parallel axis.
