摘        要：In this talk, I will present our most recent results on motion planning in 5-axis CNC machining, specifically, to distribute the wear of the tool as evenly as possible. Given a reference surface, a set of contact paths, and a toroidal cutting tool, our algorithm generates tool motions that are locally and globally collision-free, while balancing machining accuracy and tool wear through optimization. We first build 2D time–tilt configuration spaces along each path to identify collision-free regions, then merge them to derive a global tilt function controlling the tool orientation. This function, represented as a B-spline, is optimized to minimize machining error and distribute tool wear uniformly, remaining within the collision-free domain. Experiments on both synthetic and industrial surfaces demonstrate significant wear reduction without loss of accuracy.

报告人简介：Dr. Kinga Kruppa is a postdoctoral researcher at the Basque Center for Applied Mathematics (BCAM) in Bilbao, Spain. She works with Dr. Michael Barton on geometric modeling, specifically, motion planning in CNC machining. Her current research focuses on the mathematical and computational aspects of designing motions in computer-aided manufacturing. She obtained her PhD in Computer Science from the University of Debrecen (Hungary), where she specialized in computer aided geometric design and developed new methods for curve and surface modeling.
