ABSTRACT:
Helical races are formed in a curved work-piece using a suitable cutting tool by performing a double rotation of the tool and work-piece about orthogonal axes. The double rotation maintains the tool at a uniform attack angle relative to the work-piece as it forms each race with the result that the race has a uniform cross-section along its entire length.
