“…For example, Nehal et al (2012) proposed a genetic algorithm based system. Huang et al (2009) presented optimal layout and path planning for flame cutting of sheet metal. Optimization has also been used in the sheet metal forming process (Gantar et al 2002, Liu and Yang 2008, Wang et al 2008, Wang and Xie 2005.…”

Cloud computing is changing the way industries and enterprises run their businesses. Cloud manufacturing is emerging as an approach to transform the traditional manufacturing business model, while helping the manufacturer to align production efficiency with its business strategy, and creating intelligent factory networks that enable collaboration across the whole enterprise. Many production planning and control problems are essentially optimization problems, where the objective is to develop a plan that meets the demand at minimum cost or maximum profit. Because the underlying optimization problem will vary in the different business and operation phases, it is important to think about optimization in a dynamic mechanism and in a number of interlinked sub-problems at the same time.Cloud manufacturing has the potential to offer decision support as a service and medium of communication in production planning and control. To solve these problems and produce collaboration across the supply chain, this paper provides an overview of the state of the art in cloud manufacturing and presents a model of cloud-based production planning and production system for sheet metal processing.

“…The papers that consider common cuts and collisions are either complete CAM system descriptions [76][77][78][79][80], or consider an EDM application where the cutter never stops cutting [66,68], or our own work which focuses on considering simultaneously as many problem aspects as possible [6,[71][72][73][74][75]. Similarly, the papers that consider piercings and bridges are CAM system descriptions [76][77][78][79][80], our own previous work [6,73,75], and one more paper [64]. Thermal effects are only considered by three papers [50][51][52] in addition to our own previous work [74,75].…”

“…For the laser cutting path, the plate is recursively divided in strips of alternating orientation until all parts are part of a single strip. Additionally, Raggenbas and Reissner describe a set of decision rules to avoid collisions and post-optimize piercing locations Huang et al [78] deal with a cutting path problem that incorporates common cuts; however, piercing costs are negligible. They solve the problem by first determining a TSP solution between groups of contours that contain common cuts through the use of a genetic algorithm.…”

This paper presents a review of the literature on generating cutting paths for laser cutting machines. Firstly, the cutting path problem is defined including all relevant technical side constraints which exist plentifully in laser cutting. Secondly, a former classification method is updated to include all types of cutting path problems. Thirdly, a comprehensive review of solution methods and related applications is presented. Throughout the literature review, trends in research in cutting path generation and interesting areas for future research are identified.

Bridging the different parts together is considered a simple but effective strategy to reduce the number of piercing operations during laser cutting. However, fast bridging is never an easy task. In this paper, we present a near-linear bridging algorithm for the input parts with the shortest total bridge length. At first, the input part contours are discretized into a point cloud, then the point cloud is triangulated with the Delaunay standard. The shortest line segments between any two adjacent parts are found in the triangles connecting the two parts. These segments are finally extended into bridges. To solve the problem of the damages to the contour characteristics caused by the bridges, some restrictions are set on the screening of the discrete point cloud and the Delaunay triangles. This algorithm not only ensures the minimum total distance of all bridges, but also avoids the problem of generating bridge loops. Computational experiments show that the proposed bridging algorithm is much faster than that in existing commercial software. The feasibility and superiority of the algorithm are verified by actual lasering cutting experiments.
