Surface Modelling in Machining

This course presents the principles behind the mathematical representation of surfaces in ways that are suitable for computers, together with the application of such representations to computer-controlled machining processes. The Bezier, B-spline and NURBS representations are all covered, as are important surface properties, like curvature, shortest-distance algorithms, ray-intersection, surface sub-division, knot insertion, and degree elevation. Machining aspects covered are three-, four- and five-axis methods, anti-gouging methods and anti-interference checking.
