A method for grinding a feature in a work-piece includes steps of rotating a grinding wheel 10 about a first axis 20, traversing the rotating grinding wheel 10 and a work-piece 24 relative to one another along a second axis 26 that is transverse to the first axis 20 to form a feature in the work-piece 24, oscillating the rotating grinding wheel 10 and the work-piece 24 toward and away from one another in first and second opposite directions 28,30 transverse, i.e. perpendicular, to both of the first and second axes 20, 26 during said traversing step. As a result, the rotating grinding wheel 10 and the work-piece 24 are moving relative to one another along the second axis 26 and one of the first and second opposite directions 28, 30 during the traversing step such that a "saw tooth" pattern 34 is formed in the work-piece 24 to reduce burning of the work-piece. In the preferred embodiment the speed of motion along the second axis 26 and the first and second opposite directions 28, 30 are varied. A further step includes moving the grinding wheel 10 and the work-piece 26 relative to each other through the formed feature in the opposite direction to the transverse step at a constant vertical position to minimise variation in the depth of the feature is performed. |
