A COMPUTER ALGORITHM FOR ESTABLISHING THE SURFACE COORDINATE PARAMETRIC EQUATION AND GEOMETRIC MODEL OF THE COMPLEX SURFACE OBJECTS

Abstract

An algorithm is developed successfully in this paper to present the method for establishing the coordinate parametric equation of all points on the complex surface and automatically creating the 3 D geometric model of the objects. This model will be a base in surface analysis, tool selection, kinetics parameter calculation of tool, optimal toolpath algorithm building and this basic model will be used to compare the surface machining error with the real surface model after machining on the Coordinate Measurement Machine (CMM) so that we can find out the suitable solution in modification and optimal control whole of the machining process of the complex surface objects on CNC machine and the available CAD/CAM software in Vietnam.
