Comparative study of tool path strategies in CNC machining for part with B-spline surfaces

CNC machines are widely used in production of various machinery components including turbine blades, impellers, rotors, propellers etc. Most of these components are built-up from free form surfaces which considered complex shapes and required proper set up for machining. This paper presents optimiza...
