Cutter Engagement Feature Extraction by Using Dexel Representation Solid Model

Abstract:

Article Preview

Computer simulation of the cutting force change in a milling process is important for realizing more stable, precise, and efficient metal cutting. In the latest cutting force simulation method, a cutter engagement feature representing a contact area between the milling cutter and the workpiece must be extracted for each small motion of the cutter. In this paper, a new algorithm is proposed for computing a cutter engagement feature based on the dexel representation of the workpiece. Most prior studies compute the feature based on the cutter removal volume of the workpiece. Differently from them, our technology to propose computes the cutter engagement feature based on the contact analysis between the cutter and dexels representing the workpiece shape. An experimental system is implemented and some computational experiments are performed. Our system can achieve the total cutter engagement feature extraction of a complex 3-axis NC milling process in a few minutes.
