ABSTRACT:
Apparatus and method is disclosed for forming an elliptical surface in a mirror 10. The mirror blank is rotated about a given axis and the cutting tool tip 24 is pivoted about an axis C which is generally perpendicular to and spaced from the workpiece axis 16. As the cutting tip 24 moves in an arcuate path about point C the instantaneous radius R between the cutting tip and the C axis is adjusted by way of a linkage 34 which translates movement generated by a cam surface 36 and follower arm 32 into horizontal movement of the tool cutting tip 24.
