Improvements on Surface Quality of EDMed Surfaces
Surface Engineering, 2003The traditional method of producing a free form shape by Electro discharge machining (EDM) is to produce the form on the tool and plunge this tool into the workpiece. One drawback however, is the cost and wear of these tools, particularly when producing complex shapes.

Determination of Product Surface Quality
2006 IEEE 14th Signal Processing and Communications Applications, 2006Physical changes in the product surface can be determined by using digital image processing and laser scanning techniques. In this study, how to determine surface quality of the product by using both two techniques is investigated. Car bonnet is choosed as the product.

Surface quality of intraocular lenses
Journal of Cataract and Refractive Surgery, 1989We observed circular furrow-like patterns on the implanted intraocular lens surface in postoperative follow-up examination by specular microscopy. The patterns may have been deep lathe-cut marks or compression-related marks on the optics. Specular microscopy, polarized light microscopy, and scanning electron microscopy detected a similar circular mark ...

Surface Quality Prediction in Aluminum Extrusion
Key Engineering Materials, 2011The surface quality of aluminium extrusion products can be hampered by undesired surface features like die lines and pickups. In particular the presence of pickups is considered as undesirable. Surface pickups appear as intermittent torn marks on the aluminium extrusion products, often terminated with a protruding lump rising above the surface up to ...

Quality Control of Manufactured Surfaces
2010Recent literature on statistical process monitoring pointed out that the quality of products and processes can be often related to profiles, where the function relating a response to one or more location variables (in time or space) is the quality characteristic of interest.

Quality Improvement of Surface Triangulations
2006This paper presents a new procedure to improve the quality of triangular meshes defined on surfaces. The improvement is obtained by an iterative process in which each node of the mesh is moved to a new position that minimizes certain objective function.

3D surface models are often stored as indexed face sets, whereas algorithms can typically treat only a subset of the so-representable surfaces. Besides this gap between "potential" input and "allowed" input, more and more algorithms specify their input requirements at a high level of abstraction (e.g.

Objective assessment of the surface quality of coated surfaces
Insight - Non-Destructive Testing and Condition Monitoring, 2011A novel procedure has been developed for the assessment of the surface finish of in-mould gel-coated fibre-reinforced polymer matrix composites. The technique involves photographing the reflection from a coated surface on an opaque screen and analysing the image using fractal dimensions.

Visual inspection of weld surface quality
Journal of Intelligent & Fuzzy Systems, 2020Welding is an important method for modern material processing. In actual processing, due to the influence of processing accuracy and welding thermal deformation, various defects often appear in the appearance of the weld. At present, visual inspection is mainly used for the appearance inspection of welds. The detection of weld defects mainly depends on

High Quality Triangulation of Implicit Surfaces
Ninth International Conference on Computer Aided Design and Computer Graphics (CAD-CG'05), 2006We present a new high quality tessellation method for implicit surfaces in this paper. The approach can handle arbitrary implicit functions and dynamic implicit surfaces based on skeletal primitives. We first samples the implicit surface uniformly using particle fission and floating, then reconstructs a triangular mesh from the sample points using ball
