Modelling and Tool Path Generation of Complex Bezier Surface for Reverse Engineering Applications

The present work is to develop a model of three-dimensional surface for reverse engineering. A generalized surface modelling for free form surfaces has been presented in this work. Surface scanning re-modelling and tool path generation to produce the required surface are being used very frequently to develop upon an already existing product within least possible time. In this paper, complex Bezier surface patch has considered a free form surface for modelling as well as generating tool path. For Bezier surface patch, the control points have defined for the patch and using this single patch, control vertices have been created. Then within the range of Bezier parameters u and v between 0 and 1, Bezier boundary/smoothening points have been developed for these defined vertices, and by plotting these points for various rows and columns, smoothening Bezier surface patch has been generated and tool path planning is done with the help of smoothening points.
