Paper Abstract

Sources of error associated with Single Point Diamond Turning of rotationally symmetric aspheres are examined and mathematically dissected to yield equations in the form of a superposition of errors. The equations are derived from manufacturing process considerations involving CNC machining mechanics or operator observations. The types of errors reviewed here include geometry errors, displacement errors, and dynamic errors but do not include errors associated with thermal gradients.
