Abstract: In this paper, we present exact analysis and representation of the swept surfaces of a cylindrical object undergoing two-parameter rational Bezier motions. Instead of using the well-known approach for analysing the point trajectory of an object motion for swept volume analysis, this paper seeks to develop a new method for swept volume analysis by studying the plane trajectory of a two-parameter rational motion. It brings together recent work in swept volume analysis, plane representation of developable surfaces, and computer aided synthesis of two-parameter freeform rational motions. The results have applications in design and approximation of freeform surfaces as well as in tool path planning for five-axis machining of freeform surfaces.

Keywords: rational motion; swept volume analysis; enveloping surfaces; cylindrical cutters; multi-axis machining; NC machining; swept surfaces; plane trajectory; freeform surfaces; tool path planning; five-axis machining.
