A study on torch path planning in laser cutting processes part 2: Cutting path optimization using simulated annealing

Journal of Manufacturing Systems, 1999
Abstract In Part 1 of this paper [beginning on page 54], the heat flow in contour laser beam cutting was calculated by using the finite difference model, and a modified analytic model was developed based on the numerical experiments. Part 2 addresses the problem of optimal torch path planning for the 2D laser cutting of a stock plate nested with ...

Optimal layout and path planning for flame cutting of sheet metals

International Journal of Computer Integrated Manufacturing, 2009
This paper presents a two-stage methodology for the optimisation of layout and path planning that can be used in flame cutting of sheet metals. The main objective of this paper is to minimise the total travel distance of the flame gun that will not only reduce the cutting time but also the heat effect. The first stage is to use a heuristic to cluster a

A study on torch path planning in laser cutting processes part 1: Calculation of heat flow in contour laser beam cutting

Journal of Manufacturing Systems, 1999
Abstract Conductive heat transfer in contour laser beam cutting is analyzed by using a transient, two-dimensional finite difference model, and the result is combined with a simple analytic model. From the calculation results, the correlation is derived between workpiece temperature and opening angles at a corner in contour cutting.

Optimum Path Planning for Multi-robot H-beam Cutting System

2011 Third International Conference on Measuring Technology and Mechatronics Automation, 2011
Optimum path planning for multi-robot H-beam cutting system is presented to improve work efficiency. According to the working and design features of the multiple robots system, the minimum time delay method is adopted to avoid collision, and collision avoidance and path planning can be abstracted to a mathematical model to be optimized.

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.
