Reverse engineering is a way of replicating complex shapes and designs with the use of specialized hardware and software. This paper presents the methodology need- ed for obtaining the 3D virtual model starting from exist- ing models made by hand, and then editing this virtual model to manufacture molds. These are then machined using three axis CNC manufacturing equipment. The pa- per approaches some of the key challenges for reverse engineering: repairing damaged sections in the model, recreating an ordered pattern and balancing the number of points and processing time. An analysis is made to try and optimize both the scanning, processing and machin- ing processes in order to decrease the time and costs as- sociated.
