“…Recently, a number of papers have considered direct tool path generation from digitised point cloud data. For rough and finish machining, Lin and Liu (1998) suggested methodologies to generate a tool path from digitised point cloud data by constructing a Z-map model. Park and Chung (2003) and Chui et al (2002) also presented procedures through which three-axis tool paths could be directly generated from digitised point cloud data.…”

Laser remanufacturing has been used as an approach to refurbish or to improve the surface quality of high-priced parts. However, most of the existing systems lack measuring and modelling functions, which results in the uncertainty of the quality of end products. This paper presents a three-dimensional Laser Remanufacturing System (LRS) based on the integration of reverse engineering and laser cladding. A coaxial powder feeding system is developed to meet the requirement of three-dimensional laser cladding. Meanwhile, the geometric and mechanical properties of metal parts of layers fabricated by LRS are explored. In addition, the principle, advantages and applications of the LRS system are described.

“…Basically in order to remove large amount of volume we remove certain thickness of workpiece layer by layer with flat-end mill, which was called slice-cut and also adopted in other previous research (10) . The slice-cut is done along a rough-cut surface; its thickness of a cuttinglayer can be decided by the tool parameters.…”

In this paper we propose methodologies and algorithms of NC cutter path generation for subdivision surfaces. We select Loop surface as the subdivision surfaces. A path plan including rough cut and finish-cut is developed based on the LoD (Level of Detail) property of subdivision surface. We generate a coarse mesh that covers the limit surface to implement the rough cut. For finish-cut we use ball-end mills and offset cutter contact data to generate cutter location data. In these two steps we use a Z-map model and a collision detection/correction method is presented for the interference-free of these two steps. We implement our methods and present machining results. All of these two kinds of cutter paths are computed rapidly and automatically.

“…The first method reported is the work by Lin and Liu (Lin and Liu, 1998). Authors create a rectangular mesh, a Z-map, from the digitizing lines obtained with contact or non-contact measuring devices.…”

“…Although there are many methods for tool path finishing trajectories, a few ones address the specific case of roughing. Lin and Liu (Lin and Liu, 1998) have proposed a method based on the classical Z-level roughing method. In order to overcome, difficulties linked to the huge amount of data, and the lack of continuity their work relies on a structure of the data through a Z-map calculated from the digitizing lines.…”

International audienceThis paper deals with the feasibility of direct duplication of physical objects as regards a classical approach based on Reverse Engineering. The object surface acquisition is performed using optical devices. Algorithms for tool path generation directly from the cloud of points have been developed in 3-axis machining. A n-buffer simulation completed by the real machining emphasize that direct duplication is efficient in terms of conformity to the geometry. As the surface reconstruction step is removed, the proposed process is faster and simple to implement. The last step is concerned with the extension to discrete 5-axis machining. The main issue is related to the determination of the part set-ups and the corresponding point cloud segmentation
