<p>Sliding surface in mechanical system is required to move smoothly and stop. Sliding surface can move and stop by giving adequate friction force. Friction force is controlled by developing technology creating small texture on the surface with a few micrometer to a few hundred micrometer interval. If friction force is reduced by applying the technology to large area of sliding surface of airplane, generator and machine tool so on, machining effect is rapidly improved. It is necessary to develop machining technology to create texture with high precision and efficiency. On the other hand, ultrasonic vibration is used in many manufacturing fields. It is well known that surface roughness is improved and reduce stress using ultrasonic vibration. In this study, machining technology creating wear resistant texture on large area sliding surface with high precision and efficiency using ultrasonic vibration during knurling is developed. In this paper, effect of ultrasonic vibration is examined by the fundamental experiment. A horn to amplify ultrasonic vibration is designed and made. Frequency of ultrasonic vibration is measured and it is found that desired frequency is available. In the experiment making a groove on the surface with indenter using 2 dimensional table, pressing force and friction force are measured. Pressing force and friction force are reduced using ultrasonic vibration.</p>

In this paper, an approach is presented for finding an intersection curves between triangulated mesh (designed geometry) and point cloud data (acquired geometry). We use projection based Moving Least Squares (MLS) surface as the underlying surface representation for acquired point-sampled geometry. This phase can be viewed as first step towards direct Boolean operation between such meshed surface and point cloud data. Based on MLS surface definition, an algorithm is developed to find the intersection point between plane and MLS surface. We then extend this algorithm to intersect entire mesh model with point cloud. Once intersection points are known it is possible to carry out Boolean operation and generate hybrid model.

In reverse engineering, a laser scanner is commonly used to digitize dense data in short time. Multi-view measurement is often applied in order to get whole surfaces data of part. Registration is applied to unify the different data. It becomes a critical step when the accuracy is main purpose. Registration of accurate part becomes complicated when data sets have different data distribution. Some researchers have proposed some method to solve this problem. Commonly, proposed registration based on coordinate transformation, then continued by ICP method or plane-to-plane registration. Those methods have their advantages and advantages. The shortcoming of existed plane-to-plane registration for accurate part is difficulty to define a base for registration. This proposed method is based on how to matching plane of two or more different sets in the same position and orientation. In this paper, we propose new registration method based on plane-to-plane. Cube method is used to identify the point, plane and normal in the same position. The CMM measurement is used to register data sets if there is no data coincident of two or more different laser data sets. The real application is applied to test the method and result is analyzed.

In machining processes of machine tools, guideways are subjected to the various dynamic force and moment. This paper describes the influence of the force amplitude on the dynamic characteristic of a linear rolling bearing. The carriage is excited in the feed and lateral direction respectively. The excitation force and the response acceleration of the carriage are detected respectively with a force transducer and an accelerometer. The frequency response function (FRF) is calculated based on the detected signals. To investigate the influence of the force amplitude, the FRF is measured with various force amplitude. As the result, the dynamic characteristic of a linear rolling bearing is varied with the force amplitude only when the carriage is excited in the feed direction. The frequencies and damping ratios of resonance peaks which are observed on the FRF decrease when the force amplitude increases. Then the relationship between the friction force and displacement is measured for clarifying the force amplitude dependence of the dynamic characteristic of linear rolling bearing. From the relationship between the friction force and displacement, the force amplitude dependence of the dynamic characteristic of linear rolling bearing will be due to the friction force in the pre-rolling region.

Various advantages exist if it is possible to miniaturize machine tools to fit processing object. However, simply miniaturization of a machine tool ordinary decreases the rigidity of the machine tool, and it cause decreasing of the accuracy and performance. For a miniaturization of machine tools that keep their rigidity, we proposed a new structure of small milling machine that have a work space in the shell structure. Next, the difference from usual machine tools in design was considered. Moreover, a FEM analysis was executed for spherical shell models with proposed structure, and it was shown that making a proper thickness distribution is important to enhance rigidity.

Recently CAD/CAM systems is familiarized, and products design including the free-form surface came into wide use. Now a lot of tool-path patterns are proposed for milling process of free-form surface. Therefore, it is necessary to select an appropriate tool-path pattern according to the form of surface. For such reason, the selection of appropriate tool-path based on the form of surface represented by NURBS is studied. In this research, three tool-path generating methods, iso-parametric method, iso-planar method and constant scallop height method, were taken for comparison. A free-form surface was machined with three methods, and then the machined surfaces were measured. The difference between Z coordinates of the measured point and that of the target surface was defined as the error margin in order to evaluate performance of tool-path pattern. The results showed that proper selection of milling method would get the good surface integrity.

In this research, an effective tool path generation for free form surface is investigated by using 8-axis robot system. Processing freeform surface using this robot is already done, and the way for processing freeform surface and tool path generation using this system is established. However, because of many problems, for example interference on tool and work, complexity of the algorism for tool path generation, and so on, it is difficult to process complex form, and processing is not inefficient. In this research, I consider improving the algorism for tool path generation, and suggest processing efficiently and processing complex form.

In the rough cutting process of sculptured surface machining, using rough cutting models, which are composed or large flat facets and have simple shape profiles, could effectively reduce the machining time and improve the machining efficiency. In this paper, a 3D rough cutting model generation algorithm for sculptured surface machining is presented. The proposed algorithm is based on offset and multi-resolution mesh. Offset guarantees that the rough cutting models always involve the input model, while multi-resolution mesh allows the simplification of a complex model into coarser approximations. This proposed algorithm could generate 3D rough cutting models with different resolutions from the input model. These models have simple geometric complexities and incremental volume changes. The experimental results indicate that the generated rough cutting models are suitable for rough cutting process in sculptured surface machining.

Multi-resolution display of highly detailed mesh models has been gaining considerable interest in recent years. However, most researches today are only focus on the geometric similarity. The mesh quality and machining acceptability are less concerned. In this paper, a multi-resolution mesh generation algorithm for sculptured surface machining is presented. The lower-resolution mesh can be used for rough-cut, and the higher-resolution mesh for finish-cut in machining. The proposed algorithm uses iterative edge collapse to simplify the input mesh. The approximation error is controlled by a local error metric VIV (Vertex Importance Value), and a global error bound. This multi-resolution mesh is capable of generating faithful approximations of the original model with high-quality mesh, and also capable of generating rough-cut models with simple geometric complexity and incremental volume, which is suitable for material removal process.

In connection with the worldwide increase of the environmental consciousness, eco-machining becomes one of the most important subjects in the mechanical production field. Consequently, MQL (Minimal Quantity Lubrication) machining process becomes the practical technology today. However, behavior of the mist particle at the tool-work interface in company with its lubrication and cooling effect in that interface has not been made clear. Indeed, although it is indicated that the mist particles floating in the surrounding are so small that the machining operator can be damaged by the particle, even the density of the mist at the arbitrary point can not be known. In this study, authors tried to develop a simple and small mist density sensing system by means of QCM (Quartz Crystal Microbalance) sensor conventionally used for the smell sensor. The developed system was evaluated by some experiments to check its sensitivity and reliability in the view point of the availability for the practical use. As a result, it was shown that the density of oil mist can be qualitatively obtained by measuring the resonance frequency of the circuit, and that this system is applicable to the actual production fields.

In Hot Wire (HW) cutting of the Polystyrene Foam (PF), one of the rapid prototyping methods, usually tool path must be offset to outside of the profile of final shape larger than the radius of wire. The aim of this process is to avoid over ablation induced by tremendous heat effect, because this effect heavily affects on the accuracy of the final shape and surface finish. Therefore it can be easily understood that to clarify the fundamental mechanism of the fohming process based on physical or chemical considerations and to know the amount of removal rate in advance are very important for the precision of the machining system. However, there is little study which discusses this point. Therefore, authors tried to make clear the basic behavior of PF in the HW cutting process by experimental work, and found that the natural convection have an important role. Furthermore, as the first step to estimate the amount of removal rate theoretically, numerical calculations with simple thermal conduction model were carried out. From comparison of the experimental and theoretical results, it can be concluded that in spite of the simple theoretical model, calculated removal width was coincided with the results obtained from experiments. As a result, possibility of the calculation to estimate the appropriate offset value in the hot wire machining was confirmed.

Titanium is used in many industry fields because of its high rigidity and harmlessness to human body. Titanium coloring by laser irradiation has attracted interests, however it has not been widely used in industry because it is difficult to control hue. In this research, the coloring mechanism of titanium oxide layers which is generated by pulsed Nd:YVO4 laser (wave length λ=1064nm) treatment in air was discussed. A series of colors were obtained by changing the laser irradiation parameter. By evaluating the obtained color, it is found that the brightness is related with the surface roughness. In addition, by microscope observation, it is found that the surface of the titanium and the area of titanium oxide layers after laser irradiation are affected by oscillation frequency. As the results, both the laser irradiation parameters and the surface state of titanium have to be considered for control the color.

This study is focused on the basic mechanism of the laser coloring technique to the titanium by using Nd/YVO_4 laser. Relation between laser irradiation parameters and obtained color has been carefully investigated by color evaluation and surface roughness measurement. The obtained colors changed as the input energy increase and the trend of color change matched qualitatively to the theoretical estimation assuming that the thickness of the layer becomes higher by increase of the input energy. On the other hand, as the surface became rough, the color became dark. Therefore it can be concluded that if laser parameters are suitably controlled, arbitrary value of hue and brightness can be obtained.

Color marking of titanium by titanium oxide coatings are widely used in many fields such as medical implants because they are environment friendly and safe to human body due to no dyes used. Laser irradiation is an efficient approach to obtain oxide coatings. But it has not been used widely in the industry as it is regarded difficult and not repeatable. In this research, the coloring mechanism of titanium oxide layers generated by pulsed Nd:YAG laser (3rd harmonic: λ=355nm) treatment in air was discussed. A series of colors were obtained by varying the laser irradiation pulse energy. With the assumption of formation of uniform titanium dioxide layer on titanium surface, it was confirmed that observed colors calculated by light interference theory were in good accordance with the experimental ones. For investigating hues, CIE 1931 x-y color space and Surface Profile Meter were used. In conclusion, intensity decrease according to increasing pulse energy.

Dynamic characteristics of guideways influence on not only motion accuracy of feed drives but also stability of regenerative chatter vibration which deteriorates productive efficiency of machine tools. This paper describes the influence of the frictional hysteretic behavior in pre-rolling region on dynamic characteristics of the rolling guideway which is widely used in machine tools. The numerical analysis by using the friction model is conducted. The simple friction model based on Masing rule is constructed to identify the inherent factor which affects to the dynamic characteristics of the rolling guideway. The hysteretic behavior generates the harmonic and super harmonic resonances in the frequency response, and causes the excitation force dependency of the frequency response. The tendency of this excitation force dependency varies only with the change rate of friction in the pre-rolling region. If the change rate of friction was large, the harmonic resonance frequency would be high. Also the compliance at the harmonic resonance increases monotony in accordance with increasing the excitation force amplitude. Finally, the experiment with the roller guideway is conducted to prove the validity of the numerical analysis.

The purpose of this research is making a valuation of relationship between the structural color appeared on titanium and the condition of laser irradiation. The pulsed Nd-YAG laser that wavelength is 355nm is irradiated to titanium alloy in scanning lines. Various structural colors are appeared by changing pulse energy, pulse interval time, pulse overlap rate, and scanning lines interval. These colors are caused by interference of reflected light between the surface of titanium alloy and thin film of compound that formed by laser irradiation. Therefore, the hue can be showed by thickness of thin film quantitatively. As a result of laser irradiation, thickness of compound is shown in the form of cube root of pulse energy and it is proportional to the pulse overlap rate and scanning lines interval. In addition, the roughness of surface before irradiate laser do not influence to the hue of structural color, and the composition of compound is similarly regardless of the hue. The relationship of the film thickness and pulse interval time can't be estimated.
