Iterative Space-Cutting Fast Marching Tree Algorithm for Obstacle-Aware Path Planning in Focused Ultrasound Robotic Systems

2025 18th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI)
Magnetic Resonance Imaging-guided High Intensity Focused Ultrasound (MRI-HIFU) requires precise acoustic path planning to ensure safety. This study proposes an Iterative Space Cutting-enhanced Fast Marching Tree algorithm (ISC-FMT*) for HIFU path ...

The cutting path and tool selection problem in computer aided process planning

Journal of Manufacturing Systems, 1989
Abstract This paper is concerned with minimizing the sum of the tool setup and volume removal times associated with metal cutting operations on a flexible machine. The problem is of interest to most repetitive manufacturers because any reduction in processing time translates directly into cost savings.

A two-step feedrate planning of polygonal path for micro laser-cutting machines

The International Journal of Advanced Manufacturing Technology, 2019
The sample machined with the polygonal path is a common feature in a micro laser-cutting machine. It brings a difficult problem in feedrate planning when the machining accuracy is limited to the scale of sub-micrometer. In this paper, the transition feedrate at the node point is determined by the dynamic capacity of a machine.

Study on Path Planning of Involute Tooth Surface Milling With General Cutting Tool

Volume 10: 2019 International Power Transmission and Gearing Conference, 2019
Abstract Milling involute tooth surface with universal cutting tool overcomes the difficult problem of customizing tool for nonstandard gear machining. It is difficult for gear manufacturers to gain an advantage in market competition because of the long cycle of customized cutting tools.

Neural network modeling for tool path planning of the rough cut in complex pocket milling

Journal of Manufacturing Systems, 1996
Abstract This paper presents a new approach to rough-cut tool path planning of pocket milling operations. The key idea is to formulate the tool path problem into a TSP (traveling salesman problem) so that the powerful neural network method can be effectively applied. Specifically, the method is composed of (1) digitization of the pocket area into a
