The main purpose of Reverse engineering is reconstructing surface model from the real object. However, in the process of reconstructing surface model, surface connecting technique plays a decisive role, and it is hard to merge Free-from surface in traditional way, especially in complexity and irregular one. For the reason, made the traditional model Digitization by using Mathematics model is more exact and efficient, and comparing to traditional way, using CAD system to edit, design and analyze surface is easier and expeditious.
This research focuses on constructing constant radius blending surface of two surfaces. It investigates the need of technique and theory in the process of constructing blending surface and the relation of trimming between blending surface and original surfaces. Trimmed surface represents the surface which has been trimmed, and then analyzing the quality of blending surface from the connecting position of blending surface and original surface and the continuity of slope. Such algorithms, including surface offset and intersection curve of surfaces and it also algorithms the timing and appropriateness of using each calculation.
