Machining an Elliptical Shaft on a Lathe

A method is described for machining a shaft with an elliptical cross section which requires no special cams or master patterns.

The method employs the use of a lathe as is shown in the figure. Cylindrical stock work piece 1 is clamped in the block 2, which is mounted at the angle Theta on the lathe cross side 3. On the lathe face plate 4 is mounted the riser block 5, to which is clamped the toolholder block 6 and the cutting tool 7. The cutting tool 7 cuts circumferentially about the work piece 1 as the work piece 1 is advanced in the direction of feed 8. The cutting operation results in imparting to the work piece 1 an elliptical cross section, having a major axis parallel to the plane containing the critical angle Theta.
