Design and Modeling of Tool Trajectory in C0 Continuity Concept by Importing the IGES Neutral File

Abstract

A common task in geometric modeling is to interpolate a sequence of points or derivatives, sampled from a curve, with a parametric polynomial or spline curve. To do this the first step is to choose parameter values corresponding to the interpolation points. In a parametric environment, user can completely define a geometric feature with some parameters. This paper has an aim to generate a smooth tool trajectory spline for machining a workpiece. With the spline technique MATLAB program has been proposed for simulation of cutter contact points in the trajectory. The author has gone through C⁰ continuity concept and at last the simulated result has been shown by MATLAB program in its output.
