Wheel loading is one of the most serious problem on high efficiency grinding, creep feed grinding for difficult-to-grind material by using finer grain wheel. In this study, the grinding fluid is excited by ultrasonic oscillating effecter, which is set between fluid supplying nozzle and wheel. The performance was verified on general surface grinding machine with vitrified WA wheel. By grinding a pure titanium plate with conventional grinding fluid, severe loading caused drastic increase of grinding force, burned ground surface was obtained. On the other hand, the ultrasonic excited fluid generated good surface with uniform grinding force, and inhibit the temperature rise at the grinding point.

A method for variational modeling of individual hands from a template hand model is described. The marked individual hand is reconstructed based on image-based multi-view 3D model reconstruction technique. According to hand joint anatomical knowledge, a single axis rotation assumption is proposed for estimating the joint axes and joint centers by the positions of dot markers at the backside of the hand skin in different hand postures. On the other hand, the skin surface of the template hand model is hierarchically partitioned into segments according to the hand surface anatomy by main creases on palmar side. The segments of the template hand model are scaled according to the feature dimensions of the reconstructed individual hand model. Finally, the template hand model scaled in segment-wise way is registered to the reconstructed hand model by a rough alignment process where the gravity center of the point sets on the creases of both models are matched and a fine alignment process where the segments of both models are matched based on ICP algorithm. Compared with previous works, the method is more subject-friendly, inexpensive, and efficient.

To improve the overlay accuracy in semiconductor lithography equipments, it is required to restrain the deformation of the structure body caused by vibration. For development of the structure body with countermeasures against vibration, vibration analysis has been utilized so effectively. This report describes the simulation results which correspond to the experimental evaluation of semiconductor lithography equipments in sub-nanometer order.

Recently, development of porous metal has been becoming active to meet the requirement of machinery industry as a high strength material in spite of its low–density. To evaluate its properties and quality, material testing is conducted, however, the evaluation simulated on a computer is much more efficient. In fact, converting a large piece of porous metal into digitized mesh data is significantly difficult because of its complex inner structure. X–ray computed tomography(CT) scanning technique enables us to obtain the information of internal structure. Furthermore, reconstruction algorithm produces volume data of test object. Generally, conventional methods are utilized to generate mesh data from volume data whose drawback is generating too much elements resulting in high computational cost. We propose an approach to generate hexahedral meshes particularly designed for porous structure by modeling each pore with spheres from volume data. Data conversion is conducted through a series of processing, which are labeling, spherical approximation, shape approximation, region segmentation and meshing. The result substantiates feasibility of proposed method that generates shape–approximated and finite–element–simulation–available mesh data with fewer elements.

This paper proposes a method for reconstructing a 3D shape from a point cloud obtained by scanning an object consisting of a wire structure. When scanning a wire structure, the point cloud has many missing parts; thus, it is difficult to apply standard methods for reconstructing a surface. To solve this problem, the proposed method first extracts the topology of a wire structure as a graph and then reconstructs the scanned object as a combination of cylindrical surfaces centered along the edges of the graph. Our method uses Delaunay tetrahedralization to make the initial edges and simplifies the edges by applying iterative edge contractions to extract the graph representing the wire topology. Furthermore, an optimization technique is applied to the positions of the cylindrical surfaces in order to improve the geometrical accuracy of the final reconstructed surface.

In recent years, in conjunction with the spread and improvement of the performance of industrial X-ray CT scanners, a demand to achieve accurate surface reconstruction of measured objects is increasing. However, it is still impossible to reconstruct the shape of measured objects made of metals with high accuracy due to unsufficient transmittion rate of X-ray through objects. This paper proposes a novel method which reuses X-ray projection images (sinogram) to improve the accuracy of the reconstructed shape by correcting the CT values, which is done by fitting silhouette-lines of the mesh to the sinogram. Reusing the sinogram has potential application to improvement of the reconstructed mesh accuracy.

Metal cutting process is analyzed by PSPG (Pressure Stabilizing/Petrov-Galerkin) rigid-plastic FEM (Finite Element Method). PSPG method can treat the incompressible condition by using the same interpolation function with nodal velocity and pressure. Triangle and tetrahedral elements are used to simulate the metal cutting process. Chip formation process is analyzed by PSPG FEM, and simulation results such as chip curl is shown.

A non-rigid cutting mechanism has been developed for the machining of materials in micro/nano scale. This mechanism is proposed for the fabrication of micro-structured features, such as micro grooves, on brittle materials, specially, when such features should be fabricated on curved or inclined surfaces, due to the capability of the mechanism developed to fabricate grooves with a constant cutting depth. On the other hand, it is know that brittle materials can be machined in ductile mode (crack free) under a sufficient small depth of cut. To find the critical cutting depth on glass, some cutting experiments were performed on an inclined surface, presenting the results on this paper. At the same time, it was observed the influence of the rake face angle of the tool during the cutting process. As result of this experiment, micro-grooves with cutting depths over 3 microns were achieved on ductile mode.

Improving materials surface functions using micro-textures is of great interest in various fields. The authors have also performed to improve the photocatalytic surface functions by introducing the microcutting textures and achieved an improvement in the hydrophilicity, which is one of the photocatalytic functions, due to the increase in the real surface area. In this report, vibration assisted microcutting was conducted on a pure aluminum workpiece using an edge of the diamond indenter as the tool rake and a depth of cut of less than zero in order to fabricate finer and more complicated micro-texture. As a result, finer and more complicated microcuttting surface texture composed of numerous plastically deformed micro embossments, impressions and flat portions was successfully fabricated on the workpiece.
