Efficient Volume-Generation During the Simulation of NC-Milling

  • Chapter
Mathematical Visualization

Abstract

This paper presents an efficient and robust algorithm for the geometric determination of swept volumes during the simulation of numerical controlled (NC-) milling. The boundary Ψ of the volume swept by a cutter Φ is represented polygonally by using instantaneous helical motions to exactly determine the line of contact between Φ and Ψ.

Applying concepts of differential geometry allows a better and more efficient approximation of tool paths. Tool paths are explicitly calculated when a design surface Γ is to be milled along prescribed curves.

We also describe how to quickly determine a polygonized representation of the truncated material during the milling process by means of “Γ-buffering”. This polygon-oriented algorithm is suitable for Boolean subtractions and error assessment.
