Generation of precise contact motions for freeform geometry is essential for many applications such as mechanical and manufacturing engineering and motion planning in robotics. Yet contemporary approaches construct the contact motions of geometric objects only for simple geometric objects, typically those bounded by line segments and circular arcs. In this talk, we present an efficient algorithm for constructing precise contact motions (within machine precision) to the case of general freeform planar objects bounded by B-spline curves. We then extend the algorithm to the tool path computation for the CNC machining.
